one of the secrets of zone trading/SR is escalating unit size during volatile session. Meaning, 1st violation unit size 1, 2nd violation unit size 2, 3rd violation unit size 4, ...till breakout occurs. your using position sizing to amplify a breakout. It takes balls to follow through with it. might do a camtasia session to show it in action. The key becomes which zone your going to wage your battle in. Ideally it is at the edges of weekly ATRs.
another secret, trades should only be entered during the calculated spike in volume, such as the 1:30 pm EST USA time in ES. your increasing the chances of price seperation.
