MT5 Multitimeframe Backtest and Indicator draw trendline

New comment
 

I have create a very simple EA which calls 4 times the same indicator from different timeframes.

That way i can watch all 4 timeframes how they develop with the indicators on the chart.


But now i have find a problem, i have create a simple indicator which just draw a trendline from last high to current high. The problem is when i call this indicator with my EA on the backtester visual mode, it draw all 4 trendlines into the same chart, but i want him to draw every trendline in the own chart, so for example the H4 timeframe is running in the visual mode backtester then he should draw the trendline also in this H4 chart.

Does the MT5 backtester dont allow to draw objects on other timeframe charts or must i just change my indicator code?

Here is the code from my indicator "Custom5":

can the mt5 not draw trendline objects on other charts in multitimeframe backtest, maybe somebody can just answer this small question?
 

You could use a switch.

switch(Period())
{
 case PERIOD_H1:
  {
   // draw H1 trend
  }
 break;

 case PERIOD_H4:
  {
   // draw H4 trend
  }
 break;
}

If you want to draw on other charts you have to use the:

ChartID();

Thank you for your help, i did not get a notification so i did not know somebody have write me in the forum.

I have create a simple MT5 EA which use ChartID() to draw trendline objects, normaly he should draw on the H1 and D1 chart a trendline, but i see that he again draw both trendlines in the same H1 chart.

Can you please copy and paste my example EA and tell me what i have code wrong?

It's not possible currently to draw on other charts within the Strategy Tester.
 
ok thanks for the info
 
I think you must change code to draw trendline as buffer of indicator.

I think you must change code to draw trendline as buffer of indicator.

that could be possible because i did also see that indicators like moving average or rsi are display in the strategy tester charts from other timeframes. but it can be little bit to difficult to code that. easyer could be to code a period converter for MT4 which update offline charts during backtest, i did see some youtube videos where people show how it works. then you can put your template with all indicators which you want on the offline charts.
