Hi v.kredov,

Your indicator throws an exception here

ResultClose.Count is 1 and you are trying to access index -1. You should fix this before we can proceed.

This line can be commented out, it is not critical. In the real chart, it does not swear, in backtest mode, execution does not reach this. Or we can use this filter

if(ResultClose.Count > 2 && Bars.ClosePrices.Count > 1)
                    Chart.DrawTrendLine("Point" + (Bars.ClosePrices.Count - 1).ToString(), Bars.ClosePrices.Count - 2, ResultClose[ResultClose.Count -2], Bars.ClosePrices.Count - 1, ResultClose[ResultClose.Count - 1], "Blue", 2);

On the live chart, this error often appears when adding an indicator. When the number of indicator values ​​is not equal to the number of tool candles, despite the fact that this behavior always occurs when loading the history of the tool by scrolling the chart back.
