Keltner bounce from border. No repaint. V2 (by Zelibobla)

WARNING: despite of strategy doesn't use future data (not repaints) it doesn't consider broker`s commissions, which can be harmful for real life high frequency trading. Strategy will definitely fail on non-ordinary security behavior. But if new behavior will get stable, tuned params should make strategy profitable again.

This is the second version of this strategy I've added emergency stop-loss ordering, parametrized trade size and enabled to switch strategy entry mode. Now it looks good on bigger timeframes such as 5min (ES1!) on screenshot. You are welcome to bring new ideas to enhance performance.
