Code profiler is not working in build 646. Editior build 934.
Why after build 646 I can't run Custom indicator see the picture
I've an indicator that require some minutes of calculation in order to draw first time bars (not all chart bars, but only some hundred).
After initial calculation it adds only a single bar at time (obviously) with low processor time consumption.
But for the initial time that is required to draw initial bars, MT4 is hanged up.
It seems that MT4 don't start a new thread when a new chart is created (and expert or indicator are added to that thread), it seems instead that all MetaTrader task are stopped until the indicator exits from the OnCalculation function.
Not a good thing, this limits MetaTrader indicators to only simple, low CPU consumption algorithms.

It is not a new feature with the build 646. Indicators share a thread, while the experts and scripts rather have a dedicated thread. The documentation displays this information correctly. I think the logic for this design is quite appropriate.
Yes, I know that it's not a "new feature", it's an old limit that should be removed.
From my point of view, also in the actual MT4 version (that is miles away from ancient builds < 600) there are very little things "quite appropriate".

Horse lovers have also criticized the introduction of the automobile.
Lol, I would not call the 646 a horse. It is definitively a car, though still running on iron tires.
