Could you please share your code using the "Attach Backtest" funcionality so that we can help further?

Thank u. here is the code

While we run this algorith, we can read in the Console:
Exceeded maximum points per chart, data skipped.Graphic cards / js browsers can only handle so many points and so much RAM before they choke and crash. We've experimented and found roughly 4000 is a good mid-ground which survives on the majority of browsers. There is no sufficient data-store for high resolution charting so everything is done in ram.
Therefore we set a maximum points per chart limit of 4000 points.
