Five indicators, one job each, and why the rest can come off your screen
Published: 17 October 2026 · Last updated: 17 October 2026 · By Spencer Li, CFTe
In 2011 I wrote a post called Avoid the Indicator Trap. My point was simple: “There are only five pieces of information we can get from charts: the open, high, low, close and volume.” Every indicator is a calculation on those five, so none of them can show you anything the price has not already shown.
That still holds. But a blank chart is not the only answer, and the reason matters for how you pick your indicators.
So what are the best indicators for swing trading? The ones that each answer one question you need answered before a trade. That comes down to five jobs: moving averages for the trend, volume for the fuel, RSI for the timing, ATR for the room a stock needs, and relative strength for which stock is strongest. If two indicators do the same job, one of them goes.
Why do most swing traders use too many indicators?
Because each one feels like extra safety. A trader adds RSI, then MACD, then stochastics, then Bollinger Bands, hoping the next line will finally make the decision for them.
What actually happens is the opposite. As I wrote back then, “one may also get conflicting signals from different indicators,” and without reading the price itself, there is no way to settle the conflict. You end up waiting for five lines to agree, which they rarely do, or picking whichever one says what you hoped.
It is like driving with a dashboard full of warning lights. One light that means “low fuel” is useful. Twelve lights blinking at once just make you stop reading any of them.
What are the best indicators for swing trading?
Here is the short list, with the job each one does and a common setting. Most charting tools offer these settings as defaults or close to it.
| Indicator | Its one job | Common setting | What it tells you |
| Moving averages | Trend | 20, 50 and 200-day EMA | Which way the stock is going, and how healthy the trend is |
| Volume | Fuel | Volume vs its 20-day average | Whether big buyers are behind the move |
| RSI | Timing | 14 periods | Whether the pullback has cooled off enough |
| ATR | Room | 14 periods | How far the stock normally moves in a day |
| Relative strength | Selection | Stock vs the S&P 500 | Whether the stock is beating the market |
How do you use moving averages for swing trading?
Use three, and give each a job. The 20-day exponential moving average, or EMA, is where pullbacks in a strong trend often find support. The 50-day catches the deeper pullbacks. The 200-day tells you whether you should be buying at all.
A simple rule many swing traders follow is to look for longs only above the 200-day EMA, ideally with the three stacked in order: 20 above 50 above 200. When they are tangled and crossing each other, the stock is going sideways, and waiting is usually the better trade.
Do note that the averages are a picture of the trend, and they lag by design. They tell you what has been happening, and that is exactly why they are good at keeping you on the right side of it. The moving average indicator goes through the maths and the main types.
Why does volume matter so much?
Because volume shows you whether the big money is involved. A price move on light volume can be a few small orders. The same move on heavy volume usually means funds are buying.
The pattern to look for is volume shrinking as the stock pulls back, then expanding as it turns back up. A breakout that happens on volume well above the stock’s 20-day average is far more believable than one that happens on a quiet day. Volume indicators for trading covers the other ways to read it.

Should you use RSI or MACD for swing trading?
A trader on a technical analysis forum asked exactly this: “rsi vs macd – which one to trust more?” It is a fair question, and the honest answer is that it matters less than you think.
Both RSI and MACD are built from closing prices. Both measure momentum. So they mostly tell you the same thing, a little differently, and using both is a bit like asking two friends who read the same newspaper for their opinion. Pick one, learn it well, and drop the other.
RSI works best as a timing tool inside a trend, rather than for calling tops and bottoms. In an uptrend, the useful read is RSI cooling off during a pullback, well short of oversold, and then turning back up. The classic “buy below 30, sell above 70” reading tends to fail in strong trends. As I warned in 2011, oscillators push traders to keep fighting a strong trend, so they end up “entering counter-trend and losing money.” The RSI indicator explains the calculation.
What is ATR used for in swing trading?
ATR, the average true range, tells you how far a stock normally moves in a day. It is the one indicator that says nothing about direction, and that is exactly why it is useful.
A stock that moves 4% on a normal day needs more room than one that moves 1%. If you ignore that and use the same stop distance on both, you will get shaken out of the jumpy one again and again, even when you were right about the direction. ATR is how you size that room, and the ATR indicator post covers how it is worked out.
How do you find the strongest stocks to swing trade?
Compare each stock with the market. Relative strength, in the sense meant here, is just the stock’s performance divided by the S&P 500’s. A rising line means the stock is beating the market.
It is an easy one to skip, and it earns its place. When the market pulls back, the stocks that hold up best are usually the ones that lead when it turns. Do note this is a different thing from RSI, despite the similar name. RSI compares a stock only with its own past.
Which indicators can you remove from your chart?
Anything that repeats a job already done. If you have RSI, you rarely need stochastics or MACD as well. If you have moving averages, you probably do not need a second set of bands around them. And anything you cannot explain in one sentence, in terms of what it tells you about buyers and sellers, is a good candidate to go.
A good test: if you deleted the indicator tomorrow, would any of your trades change? If not, it is decoration. Our post on why trading indicators fail goes deeper into their limits, and if you trade currencies, the best forex trading indicators covers that market.
One more line from 2011 is worth keeping. When I wrote Avoid the Indicator Trap, I noted that if you watch professional traders at a bank or a trading arcade, “their charts are mostly blank.” A few more lines than that is fine, as long as every one of them has a job and the price is still the main thing on the screen.
So count the lines on your chart right now. Could you say, for each one, what job it does that no other line already does? For the full set of indicator guides, see the technical trading indicators guide.
FAQ
What are the best indicators for swing trading?
Moving averages for trend, volume for conviction, RSI for timing, ATR for how much room a stock needs, and relative strength against the market for picking the strongest stocks. Use one indicator per job.
What is the best moving average for swing trading?
The 20, 50 and 200-day EMAs together. The 20-day marks pullbacks in strong trends, the 50-day marks deeper ones, and the 200-day tells you whether to look for longs at all.
Is RSI or MACD better for swing trading?
Neither is clearly better, because both measure momentum from closing prices. Pick one and learn it well. Using both mostly doubles the same signal.
What RSI setting is best for swing trading?
The standard 14 periods works well on a daily chart. In an uptrend, a pullback that cools RSI and then turns up before it reaches 30 is often more useful than waiting for 30.
How many indicators should a swing trader use?
Usually four or five at most, each with a different job. More than that tends to create conflicting signals.
