Backtest is available on the Complete version.
The video is based on v10.3, we now have v11, but the principles are the same. For example … instead of clicking on the spanner / wrench we click on the System title and a drop down appears with one of the options being modify System (or modify backtest, done it 1000’s times so can’t remember! 🙂 )
Try it out on your Demo System … try buttons that look like they may do the same as shown in the video.
