If you haven't figured it out by now, you can not just blindly follow the Buy/Sell alerts. This will return moderate results.
To get the full potential out of the TradingLab indicator, you have to do a lot more than just follow the simple Buy/Sell signals. You should be incorporating price action, support/resistances, volume, divergences, risk management, etc.
If you haven't already, I would highly suggest you watch this video to get the basics on how to optimize the indicator.
We are currently in the making of creating more advanced tutorials for the indicator. So make sure to enable bell notifications for the YouTube so you get notified when a new video gets posted!
