The same Keltner Channel strategies that work for swing trading will also work for day trading. The only difference is that the movements will be smaller and quicker. To capture these smaller, quicker movements, you should reduce the period being measured and the EMA period. For example, a swing trader might use the 50 EMA on a daily timeframe. A day trader might instead use the 12 EMA on an hourly timeframe. The strategy works the same, but the settings highlight smaller-term trends. A scalper might further tighten their focus, perhaps with an 8 EMA on a 15-minute timeframe. Each trader needs to find the strategy that works best for them.
