Have a look at SuperBands, with Linear Regression Analysis on that page. That's the most profitable limit order script ever written on WL, and it uses bollinger bands, not the way John Bollinger uses them, but as a shortcut to calculating what standard deviation away from the mean the current low bar is and simply selling on the open the next day.
Realistically, that's the only system based on bollinger bands that has been shown to be long term profitable. I guarantee you'll have a nice robust backtest on the NAZ100 with that script at 1% of equity.
This is the backtest I have currently on all the data.
