Hi Justine,

As per the message you receive, some indicators are not appropriately coded and cause serious degradation of performance to cTrader. Unfortunately we cannot allow those indicators to continue running, since they serously affect the stability of the platform. You should reach out to the indicator developer to fix the issue.

Best Regards,

RE: I have the same issue with cTrader Desktop 4.1 . CancTrader tell us what criteria they have used in determining if an indicator has performance issues?

It is simply plotting a moving average line of a higher timeframe than the current chart.  This is needed when trading!

When this indicator is placed onto a XAUUSD M5 chart and set to the following parameters

Period: 272

MaType: TimeSeries

Timeframe : 15 minutes

Then run back test, that's when the issue occurs

One possible cause is below.

.

  while (bars.OpenTimes[0] > Bars.OpenTimes[0])
                    bars.LoadMoreHistory();

.

infinite loop perhaps, this will continue to load data and use all the machines resources until the platform freezes, this could be why the cTrader Sentinal removed the offending indicator.

.

I only had a quick look, but consider checking this code to see if it is causing the probem.
