Trend Following Trading System I'm trying to find a way to show on a chart the following trading system as described in Turtle Trading: Enter on a 55-day breakout and exit on a 20-day breakout in the opposite direction from your entry. I would like to see those 2 lines charted on top of any chart. I've tried to use the SMA 20 and SMA 50, but it's not working as I think it should. Any ideas? Thanks!
