One of the simple yet powerful techniques I use to allow me to quickly identify trading opportunities with minimal time and effort (typically 15 minutes a day), is to use this Excel table which combines price action with multiple timeframes.
To create this table, I observe the daily and weekly charts of various products (forex, stocks, cryptocurrencies, commodities, etc), and list down whether I think it is bullish or bearish on each timeframe. For the weekly chart, I only need to update it once a week, and for the daily chart, this takes me a few minutes a day.
Here are some chart examples:
This is the daily chart of the EUR/USD, and you can see that it just completed a pullback and is looking bullish. So under EUR, I mark it as bullish. For most products, I always benchmark them against the USD for easy comparison.
This is the weekly chart of the EUR/USD, and you can see that it is also very bullish, and rebounding off a large trendline. With the alignment of both the daily and weekly trends, this make the EUR/USD a very good long trade to be in. And since the GBP is also weak, going long on the EUR/GBP is also a good idea.
For the S&P 500, the long-term trend is bullish, but the short-term trend is bearish. In such a scenario, we will pass and wait for more price action. The goal is to take the best trades, not take as many trades as possible. Quality over quantity.
