Hello SC, I was wondering a couple of weeks why BackTest Speed is sometimes fast, and sometimes very (!) slow. It cannot be my PC (fast CPU), I use no Spreadsheets, I don't use a lot studies and I used the "Auto Trade System Bar Based Back Test" (fastes one as I understand). What I found was that the reason for this are two studies, each of it for itself as I tested: "Volume Value Area Lines" and "TPO Value Area Lines". Only if I remove both studies, the speed is OK. Interesting is that I don't use these studies in my Alert/BackTest Formulas. I used only a very small simple alert Formula. So code bug cannot be a reason. Even if I hide the studies, the speed gets so slow that BackTest is a big challenge Time wise and to be honest impossible to do. So I have to remove both studies as I said. But I would like to use them in my simple alert Formula. I am not specialist in Computer Calculation and what these studies need for calculations power in the background. I am aware of your documentation regarding the speed improvements for Backtesting. But I have unfortunately no clue what to do at this point Can you help? Could this be a bug? Thanks in Advance!

Not sure we can provide any further suggestions. Try using the Volume by Price study instead of the Volume Value Area Lines study: Volume By Price Study: Calculating and Displaying Developing Point of Control, Value Area High/Low, Volume Weighted Average Price Lines And we know you made reference to this already, but here is the relevant documentation: Auto Trade System Back Testing: Improving Back Test Performance Sierra Chart Support - Engineering Level Your definitive source for support.
