I use 1hr chart as price action tend to be more valid in this TF compared to the 15 mins or 5 mins...I hold position from 1 hr to 1 day. I'm trying to move up to the daily TF but i get very bored when i do this. Naturally, i like looking at my charts several times during the day, i can't help it , this is just who i'm. I'm currently fine tuning my intraday system so as to make me consistently profitable, this will take time..
