EventChartCustom => indicator is too slow - страница 6

[Ernst Van Der Merwe]

Добрый день,

Похоже, что OnChartEvent () большую часть времени ожидает входящую галочку перед выполнением. Не тот случай с MT4.

Кто-нибудь может подтвердить это, пожалуйста. Спасибо.

Can you please rephrase your question? Write in English.

Hi Andrey,

Attached are two pairs of similar indicators for each platform.

ChartEvent opens the necessary charts with templates that send ticks back.

The MT4 version is more responsive with higher values ​​(the time difference between an incoming tick in OnCalculate () and EventChartCustom ().

From these it seems to me that OnChartEvent () in MT5 isn't firing inbetween ticks on its chart.

Here is the fix for MT5:

   if(id>CHARTEVENT_CUSTOM && btn!=NULL)
   {
      btn.SetString(OBJPROP_TEXT,StringFormat("%s %d",sparam,lparam-tickCount));
      ChartRedraw(0);
   }
