Evidence-Based Technical Analysis by David Aronson: Summary and Key Lessons

Last updated: 3 July 2026 · By Spencer Li, CFTe

Evidence-Based Technical Analysis by David Aronson is a 2006 book that applies the scientific method and statistical inference to chart-based trading signals, arguing that most traditional technical analysis is subjective interpretation that has never been properly tested. Aronson’s core claim is simple: a pattern or indicator only earns a place in your trading if it survives a rigorous statistical test, not because it looks good on a hand-picked chart. The book teaches you how to run those tests yourself, using hypothesis testing, Monte Carlo simulation (running thousands of randomised what-if scenarios to see if a result could be luck), and Bayesian inference (updating your probability estimate as new data arrives). It is worth reading if you want to stop trading on stories and start trading on evidence. Do note that it is dense, stats-heavy, and aimed at short-term traders working mostly with stocks, so it is not a casual beach read.

Here is what the book actually argues, the ideas worth keeping, and how to apply them without a statistics degree.

Who is David Aronson?

David Aronson is a statistician and quantitative analyst who spent over twenty years in finance. He holds a PhD in statistics and has written several books on quantitative methods in markets, including this one and a follow-up on Bayesian inference in finance.

That background matters, because it tells you the lens. Aronson is not a chart guru selling you a pattern. He is a statistician asking an uncomfortable question: can you prove any of this works? Most technical analysis books never ask it. This one is built around it.

What is Evidence-Based Technical Analysis about?

The book is about using scientific methods to separate the technical analysis that works from the technical analysis that only looks like it works.

Aronson’s argument runs like this. Traditional technical analysis leans on subjective reading of charts and patterns. Two analysts look at the same chart and see two different things. That subjectivity produces inconsistent, unreliable results, and worse, it is unfalsifiable: if the pattern fails, you can always say you read it wrong rather than admit the pattern itself is useless.

His fix is to treat every trading rule as a hypothesis to be tested against data. Run the rule across a large historical sample. Measure whether its returns are genuinely better than random. If they are not, throw the rule out, no matter how convincing the chart looked. He walks through the statistical machinery to do this honestly, including how to avoid fooling yourself with data mining (testing so many rules that one looks good by pure chance).

Personally, this is the part I value most. It is not the specific tests. It is the mindset shift from “this pattern feels right” to “show me the numbers, then show me they are not luck.”

The 10 key ideas, and how to actually use each one

The book gives you ideas and a method. Most readers absorb the ideas and never apply them. So here is each core idea paired with the one practical move that turns it into something you do, not just something you nodded at.

Key idea from the bookHow to apply it
Traditional technical analysis is subjective and often unreliableStop trusting a pattern because it “looks good”; demand a tested edge before you risk money
Statistical methods raise the accuracy of your predictionsTreat every trading rule as a hypothesis and test it on data before you trade it
Use data to test your trading ideasKeep a historical sample and run your rule across all of it, not three flattering charts
Hypothesis testing and Monte Carlo simulation evaluate strategiesUse Monte Carlo (thousands of randomised runs) to check whether a result could just be luck
Indicators like moving averages and RSI are tools, not magicKnow what each indicator actually measures, then test if it adds edge in your market
Bayesian inference updates probabilities as new data arrivesAdjust your confidence in a setup as fresh results come in, do not anchor to the first read
Risk management and stop-loss orders limit lossesDefine your stop and position size before entry, every time, no exceptions
Combine technical with fundamental and news analysisUse chart signals alongside context, not as the only input
Backtesting evaluates a strategy on historical dataBacktest honestly, and reserve fresh data the rule has never seen to confirm it
Excel and software tools implement the methodsYou do not need to code; a spreadsheet is enough to start testing rules properly

The thread running through every row is the same: test before you trust.

The trap the book is really warning you about

Here is the quiet danger Aronson keeps circling, and it is the most useful thing in the book.

If you test enough rules against enough data, some of them will look profitable by pure chance. Test a thousand random rules and a handful will have a great-looking equity curve that means absolutely nothing. This is data mining, and it has wrecked more “backtested” systems than bad luck ever has.

The cure is statistical discipline. You account for how many rules you tested. You use methods like Monte Carlo to ask, “could this result have happened by random chance?” And you keep a slice of data the rule has never touched, so a strategy that only memorised the past gets caught before it costs you real money.

Most traders skip this and wonder why their amazing backtest dies in live trading. The book exists to stop that.

Where the human edge comes in

Aronson hands you the toolkit to test signals, and that toolkit gets cheaper and faster every year. A modern scanner or AI can backtest a thousand rules before you finish your coffee. That part is close to free now.

What it will not do is keep you honest. It will not stop you from running the test a hundred ways until one version looks good. It will not tell you that your beautiful backtest curve is overfit nonsense, or that you cherry-picked the sample, or that you should walk away from a system that “works” only on data it has already seen. The statistics catch the luck; the discipline to accept what the statistics say is yours. That judgment, the willingness to kill your own good-looking idea because the evidence says so, is the first of the Five Edges no machine can trade for you.

Who should read this book?

Read it if you are a short-term trader who wants to stop guessing and start testing, and you are comfortable with a book that takes statistics seriously. It includes an introductory chapter for readers new to the stats, so you do not need to arrive fluent, but you do need patience.

Skip it, or save it for later, if you want quick setups you can trade tomorrow morning. This book changes how you think, not what you trade on Monday. It is focused on short-term trading, mostly in stocks, though the testing mindset travels to any market. And it explains the statistical methods clearly without giving you step-by-step software instructions, so you bring the implementation.

Personally, I would put it on the list of any serious trader who has ever lost money on a pattern that “always works.” It is the book that explains why it did not.

FAQ

What is Evidence-Based Technical Analysis about?
It argues that most traditional technical analysis is subjective and untested, and shows how to use statistical methods, hypothesis testing, Monte Carlo simulation, and Bayesian inference, to test whether a trading signal genuinely works or only looks good on a chart.

Is Evidence-Based Technical Analysis worth reading?
Yes, if you are a short-term trader who wants to test your ideas rigorously and you are comfortable with statistics. It is dense and stats-heavy, so it is less suited to beginners wanting ready-made setups.

Who is David Aronson?
David Aronson is a statistician and quantitative analyst with over twenty years in finance and a PhD in statistics. He wrote Evidence-Based Technical Analysis and a follow-up book on Bayesian inference in finance.

Do I need to know statistics to read it?
Some basic statistics helps, but the book includes an introductory chapter for newcomers. You do not need to code; a spreadsheet is enough to start applying the methods.

What is the main lesson of the book?
Do not trust a pattern or indicator because it looks good. Treat every trading rule as a hypothesis, test it against data, and use statistical discipline (especially guarding against data mining) to make sure the result is not just luck.

What is the FOMC (Federal Open Market Committee) Meeting and How to Trade it?

Thumbnail What is the FOMC Federal Open Market Committee Meeting and How to Trade it

What is the FOMC, and Why Does It Move the Market?

Last updated: 3 July 2026 · By Spencer Li, CFTe

The FOMC (Federal Open Market Committee) is the branch of the U.S. Federal Reserve that sets monetary policy, mainly the federal funds rate (the interest rate at which banks lend to each other overnight). It meets eight times a year, about every six weeks, and after each meeting it releases a statement, economic projections, and forward guidance (its signal about where policy is headed). Markets move on these meetings because interest rates set the price of money: when the Fed raises rates, bond yields tend to rise and bond prices fall, and riskier assets like stocks often come under pressure; when it cuts, the reverse tends to happen. So when traders ask “why does the FOMC matter,” the short answer is that it is one of the few scheduled events that can re-price stocks, bonds, and currencies all at once, on a known date and time. That last part is the useful bit. You always know when it is coming.

Here is what the FOMC is, what it actually decides, and how traders read it without getting run over.

What is the FOMC and where did it come from?

The FOMC is part of the Federal Reserve System, the central bank of the United States. It was created by the Banking Act of 1935, the same act that reshaped the Fed itself. Its job is monetary policy: setting interest rates and using other tools to influence the economy.

It has 12 voting members:

  • The seven members of the Board of Governors (appointed by the U.S. President, confirmed by the Senate, serving 14-year terms).
  • Five of the 12 Federal Reserve Bank presidents (chosen by their own Reserve Banks, serving one-year terms on the committee).

So it is not one person turning a dial. It is a committee, and committees disagree, which is why the dissents in a vote are worth reading.

How does the FOMC operate?

The committee meets eight times a year, roughly every six weeks, on a schedule set well in advance and published on the Federal Reserve’s website. Meetings are held in Washington, D.C., and usually run two days.

The “set well in advance” part is the trader’s gift here. Unlike most market-moving news, an FOMC meeting is on the calendar months ahead. You can plan around it.

What comes out of an FOMC meeting?

After each meeting, the FOMC publishes a statement. It covers current economic conditions, the policy decision, and anything else the committee wants on the record. It is one of the most closely read documents in finance because it shows the committee’s thinking, not just its action.

Here is what the statement and its companion releases actually contain, and why each line matters to a trader:

What is releasedWhat it tells youWhy a trader watches it
Federal funds target rangeThe current overnight interest rate bandDirect driver of bond yields and the cost of money
The vote (and any dissents)How united the committee isDissents hint at where policy could swing next
Economic projectionsExpected path of rates, GDP, unemployment, inflationShapes the outlook for stocks and riskier assets
Assessment and balance of risksThe committee’s read on the economyFrames whether the bias is toward tightening or easing
Forward guidance / language changesSignal about future policyOften moves markets more than the rate decision itself

Two more timing notes worth knowing. The data in the statement is not revised after the meeting, but the committee issues fresh projections and may tweak the statement language at every meeting. And the minutes, the detailed account of the discussion and reasoning, come out three weeks later. The statement is the headline; the minutes are the footnotes, and the footnotes sometimes move the market a second time.

How do traders and investors actually use FOMC data?

The statement and projections shape the direction of interest rates, and through rates, the value of stocks, bonds, and currencies. Most traders watch a few specific things:

  • The rate decision itself. A hike tends to push bond yields up and bond prices down; a cut tends to do the opposite. Fixed-income positions react first.
  • The economic projections. If the committee expects strong growth, traders may lean toward stocks. If it expects weakness, money often rotates toward the relative stability of bonds.
  • The forward guidance. If the Fed signals rates will stay low for a while, that can support stocks in the short term. If it signals hikes are coming, traders may tilt defensive.
  • The language changes. A few changed words on inflation or the balance of risks can tell you which way the committee is leaning before the numbers do.

Notice the pattern. None of this is about predicting the decision. It is about reading the committee’s bias and positioning for the direction of travel.

News trading on FOMC data

“News trading” means trading the reaction to a scheduled release, in this case the FOMC. A few ways traders approach it:

  • Interest rate decisions. A surprise hike can knock bond prices down as yields jump; a surprise cut can lift them. Traders adjust positions around the gap between what was expected and what was delivered.
  • Economic projections. Stronger-than-expected growth projections can support stocks; weaker ones can weigh on them.
  • Forward guidance. A shift in guidance changes expectations for future policy. A signal of near-term hikes, for instance, can pressure bond prices ahead of the actual move.
  • Statement language changes. A change in tone on inflation or risk can reset expectations for rates, GDP, unemployment, and inflation all at once.

Personally, I am cautious with trading the FOMC release itself. The first move is often a head-fake: price spikes one way on the headline, then reverses once traders finish reading the detail. The spread widens, the volatility is brutal, and the algorithms are faster than you are. For most swing traders, the better edge is not guessing the number. It is knowing a high-volatility event is on the calendar and managing risk around it, sizing down, or simply standing aside until the dust settles.

Where the human edge comes in

A news calendar will flag the FOMC date for you. A model can even forecast the rate decision. Neither will tell you to size down into the event, to ignore the first 15-minute whipsaw, or to skip the trade entirely on a day when the edge is just noise. The calendar is the easy part. Knowing when not to trade an event this volatile is judgment, the first of the Five Edges that no algorithm trades for you.

FAQ

What does FOMC stand for?
FOMC stands for the Federal Open Market Committee, the branch of the U.S. Federal Reserve that sets monetary policy, mainly the federal funds interest rate.

How often does the FOMC meet?
The FOMC meets eight times a year, about every six weeks, on a schedule published in advance on the Federal Reserve’s website. Each meeting usually runs two days in Washington, D.C.

Why does the stock market move on FOMC days?
Because the FOMC sets interest rates, which set the price of money. A rate change or a shift in forward guidance can re-price bonds, stocks, and currencies at once, so traders react fast to even small surprises.

What is the difference between the FOMC statement and the minutes?
The statement comes out right after the meeting and gives the decision and the committee’s headline thinking. The minutes come out three weeks later and give the detailed discussion and reasoning behind the decision.

Should beginners trade the FOMC announcement?
For most beginners, no. The first move after the release is often a head-fake that reverses once the detail is read, and the volatility is hard to manage. It is usually safer to size down or stand aside around the event than to trade the headline.

Weekly Market Wrap: Is this Finally a New Bull Market?

2022 09 19 21 00 30

Investors’ views on inflation, recession risk, and monetary policy were fickle throughout much of 2022.

Recently, a positive bias has emerged, reflected in the downward shift in interest rate expectations and upward move in securities prices since mid-October.

Investors appear to be interpreting economic data as evidence that a dovish pivot (Fed stopping interest rate hikes and possibly cutting them) is imminent.

Bad news (slowing job growth, dismal economic survey data, falling property values, negative real wage growth) is seen as good news when viewed through the lens of inflation and monetary policy.

But what is missing in this discussion is the real economy and what may have to happen to it for this market narrative to play out.

The dovish pivot narrative is driven by the expectation that U.S. inflation will continue to decline at a fairly rapid rate.

However, it’s also noteworthy that the Fed’s success in slowing inflation thus far has occurred while China, the world’s second-largest economy, has been hampered by pandemic-related restrictions.

The Fed is typically prone to keeping policy either too tight or too loose for too long.

Fed officials only have to look back at “the great inflation” of 1965 to 1982 to see what can happen when policy is loosened too quickly.

The market’s optimism could make it more likely that the Fed keeps tightening policy.

So, all things considered, the risk of over-tightening seems to be higher than the likelihood of a premature pivot.

What would cause the Fed to make a significant shift in policy?

Most likely a meaningful recession or market crisis – risks that aren’t being reflected in today’s earnings expectations or credit spreads.

Investors are focusing far more on what negative economic data means for interest rates than the potential implications for the real economy.

Weekly Market Wrap: Slowing Growth & Earnings in the US?

Uchisar Turkey

US nominal growth is experiencing a significant deceleration, as evidenced by declining services PMI and lower momentum of Non-Farm Payrolls, with a negative rate of change for real growth and moderating wage growth indicating negative inflationary pressures.

Inflation in the US is currently affecting services the most, which is where nearly two-thirds of consumer spending goes.

Services include housing, insurance, healthcare, education, travel and hotel bookings, subscriptions, streaming, telecommunication, haircuts and more.

Inflation in the Eurozone is increasing due to excessive printing of real-economy money and a relatively inelastic basket of goods and services.

European core inflation may lag US core inflation by 6 months but it is expected to continue to increase over the next 3-6 months, which will force the ECB to be hawkish.

The Chinese economy is experiencing a significant reopening, which is expected to boost growth and force Emerging Markets fund managers to reallocate to China and other countries.

This push from the Chinese reopening is offset by the pull of a deteriorating global growth and inflation picture.

In light of these mixed news, has the stock market bottomed, or was the recent rally a bull trap?

What is Epicureanism? (11 Practical Ways to Apply it in Your Life!)

Thumbnail What is Epicureanism

What Is Epicureanism, and How Do You Apply It in Daily Life?

Last updated: 3 July 2026 · By Spencer Li, CFTe

Epicureanism is an ancient Greek philosophy, founded by Epicurus in the 4th century BCE, that treats pleasure as the highest good but defines pleasure as the absence of pain and anxiety, not the chase for luxury. The goal is a calm, stable contentment the Greeks called ataraxia (a state of inner peace and freedom from disturbance). You reach it not by acquiring more, but by wanting less: living simply, keeping good friends close, calming your fears (especially the fear of death), and being grateful for what is already enough. To apply it day to day, you trim unnecessary desires, invest in friendship, take care of body and mind, and practise being content in the present. It is, in short, the opposite of the modern “more is better” treadmill.

So no, Epicureanism is not about indulgence, even though the word “epicure” now means a lover of fine food. Epicurus himself lived on bread, water, and the occasional pot of cheese. Let me explain what he actually taught, and how you can use it.

What is Epicureanism?

Epicureanism is the philosophy that the point of life is to pursue pleasure and avoid pain, but with a careful definition of what pleasure means. For Epicurus, the highest pleasure is not a thrill or a feast. It is ataraxia: a steady, untroubled peace of mind.

The path to it has a few clear pillars:

  • Live simply. Want less, and most of your anxiety about getting and keeping things disappears.
  • Calm your fears. Especially the big two, the fear of the gods and the fear of death, which Epicurus argued are both unfounded.
  • Keep good friends. Epicurus rated friendship above almost everything else for a happy life.
  • Use reason. Understand how the world actually works, and irrational dread loses its grip.

Personally, I find the core move underrated. Epicurus did not say “get more so you feel less anxious.” He said “want less, and the anxiety has nothing to feed on.” That is a different operating system from the one most of us run.

Where did Epicureanism come from?

Epicureanism was founded by Epicurus, born on the island of Samos and later settled in Athens, where he set up a school in a garden on the edge of the city. The school took its nickname from the place: “The Garden.”

He built on two earlier ideas. From Democritus he took atomism, the view that everything is made of tiny, indestructible particles (atoms) moving through empty space, and that natural events can be explained by those atoms rather than by the whims of gods. From the Cyrenaics he took the idea that pleasure is the goal of life, then corrected it: true pleasure, he argued, is found in inner peace, not in sensual indulgence.

The Garden was unusual for its time. It welcomed women and even enslaved people as students, which was rare. Epicurean communities, also called Gardens, spread across the Greek and Roman world, and the philosophy stayed influential well into the Roman period.

What does Epicureanism actually teach? (the common misreadings)

The biggest trap with Epicureanism is the modern word “epicurean,” which suggests a person devoted to luxury and rich food. That is almost the reverse of what Epicurus meant. Here is the gap between the popular version and the original, side by side.

Common misreadingWhat Epicurus actually taught
Chase as much pleasure as possibleChase the absence of pain and anxiety (ataraxia); a calm mind beats an excited one
Indulgence and luxurySimplicity and moderation; bread and water, friends, a quiet life
Pleasure means sensual thrillsThe highest pleasure is mental tranquillity, not bodily excitement
Fear death and the afterlifeDeath is nothing to us; while we exist it is not here, and when it comes we do not
More possessions equal more happinessMost desires are unnecessary; contentment comes from wanting less
Friends are optionalFriendship is one of the surest sources of a happy life

Do note that, this is why classifying Epicurus as a hedonist is misleading. He was a hedonist only in the technical sense that pleasure is the goal. In practice, his prescription looks closer to a minimalist monk than a party host.

What are the benefits of Epicureanism?

Adopting Epicurean principles tends to deliver a handful of practical benefits:

  • A simpler, calmer life. Cutting back on excess removes a large source of stress and craving.
  • Inner peace (ataraxia). Wisdom and self-control, applied steadily, produce a stable contentment that does not depend on the next acquisition.
  • Stronger relationships. Treating friendship as essential, not optional, builds a support network that carries you through hard times.
  • Less fear. Reasoning through your fears, including the fear of death, removes a lot of background dread.
  • Clearer thinking. Reason and logic, applied to your own life, replace superstition and panic with understanding.
  • A more ethical life. Living virtuously, with kindness and fairness, is treated not as a chore but as part of the good life.

How do you apply Epicureanism in daily life?

You apply Epicureanism by deliberately wanting less, investing in people, calming your fears, and practising contentment in the present. Here are the practical moves, drawn straight from the philosophy.

Live simply and moderately. Avoid excess. Focus on the essentials. A simple daily habit: set aside a few minutes for reflection, and practise gratitude for what you already have.

Invest in friendship and community. Spend real time with friends and loved ones. Build a supportive circle around you, whether through a club, a shared interest, or community work.

Practise self-control and wisdom. Use a daily practice, meditation or quiet study, to strengthen self-control and keep learning about the world and yourself.

Mind your thoughts and emotions. Journaling and mindfulness help you notice negative thought patterns and replace them with steadier ones.

Live virtuously. Kindness and fairness are part of the package. Small, repeated acts (helping someone, volunteering, watching how your actions land on others) compound.

Cultivate gratitude. Keep a gratitude journal, thank the people who matter, and take time to appreciate the everyday and the natural world.

Protect body and mind. Exercise, eat well, sleep enough, and seek help when you are struggling. Epicurus put avoidance of pain at the centre, and your health is the foundation of that.

Find balance. Pursue pleasures, but do not become a slave to any one of them. Set limits, and keep variety in your life.

Be content with what you have. Set realistic expectations, and notice what actually brings you contentment rather than what you are told should.

Live in the present. Stop replaying the past and pre-living the future. Focus on the task in front of you and the moment you are in.

Aim at ataraxia. The thread through all of the above is inner peace. Understand your place in the world, control your desires, and the calm follows.

Hence, the practical heart of Epicureanism is not a single dramatic change. It is a steady trimming of what you crave, paired with a steady investment in what reliably makes life good.

Who are famous examples of Epicureans?

Several historical figures lived by, or were shaped by, Epicurean ideas. Do note that, some applied the principles loosely rather than strictly, filtered through their own time and beliefs.

  • Lucretius: Roman poet and philosopher, and the great popularizer of Epicureanism in Rome. His poem De Rerum Natura (On the Nature of Things) lays out the whole system. He urged people to focus on the present and to stop fearing death, which he saw as a natural part of the cycle of life.
  • Horace: Roman poet and a contemporary of Lucretius, who wrote often about Epicurean themes. His refrain was to live simply, avoid excess, focus on the essentials, and be content with what you have.
  • Epictetus: A Greek Stoic philosopher who began life enslaved. Primarily a Stoic, he shared the Epicurean stress on controlling your desires and accepting what you cannot change, and on building inner strength rather than chasing possessions.
  • Seneca: Roman philosopher, statesman, and playwright. Also primarily a Stoic, he drew on Epicurus too, quoting him approvingly on living virtuously, simply, and free from fear.

Concluding thoughts

Epicureanism offers a different answer to the question of how to live well. Instead of chasing fleeting pleasures and possessions, it asks you to focus on the essentials, live simply, keep good friends, calm your fears, and find contentment in the present.

I think its central insight holds up remarkably well after two thousand years. We spend a lot of energy trying to add things to our lives to feel at peace. Epicurus quietly suggests the opposite: subtract the unnecessary, and the peace was available all along.

Now that you have the gist of what Epicureanism is and how to apply it, do you think it is a philosophy you would want to adopt? And if you already live by some of it, what other practical ways have you put it to work? Let me know in the comments.

FAQ

Is Epicureanism about indulgence and luxury?
No. The modern word “epicure” suggests a lover of luxury, but Epicurus taught simplicity and moderation. He defined pleasure as the absence of pain and anxiety (ataraxia), and lived on bread, water, and the company of friends.

What is ataraxia?
Ataraxia is the Epicurean goal: a state of inner peace and freedom from disturbance. You reach it through wisdom, self-control, simple living, and by calming your fears rather than feeding your desires.

Is Epicureanism the same as Stoicism?
No, but they overlap. Both prize self-control, reason, and freedom from fear. Stoicism centres on virtue and accepting what you cannot change; Epicureanism centres on pleasure (defined as tranquillity) and on simplicity and friendship.

What did Epicurus say about death?
Epicurus argued that death is “nothing to us”: while we are alive, death is not present, and once death comes, we no longer exist to experience it. The point was to remove the fear of death as a source of anxiety.

How do I start applying Epicureanism today?
Start small. Trim one or two unnecessary wants, invest real time in a friendship, take care of your sleep and health, and spend a few minutes each day on gratitude and reflection. The philosophy is built from steady habits, not grand gestures.
