The timeframe I use is the 5 minute timeframe.
I’ve tried the 1 minute, but I found it to be too short. It just goes by too fast and there is too much noise. Plus, the earnings per trade on the 1 minute were too low with respect to the commissions that I was being charged.
The 3 minute is also too short for me.
Therefore, I like to use the 5 minute as I feel it is just right. Not too long (I can’t sit through 15 minute candles at a time), and not too short such that everything just happens too quickly.
I’m very happy with the 5 minute timeframe.
