Hide indicator display on backtest MT5

[Achmad Hidayat]

In MT4 to hide indicator during backtesting using this script inside EA :

int init() {
   HideTestIndicators(TRUE);
   return (0);
}

How to write similar code in MT5?

Thank you, but I can't apply to this EA (example is part of multi currency EA "exp_tema"). How can I apply to this EA? Full EA in here : https://www.mql5.com/en/code/450

Hi achidayat,

Did you ever read the explanation on that link https://www.mql5.com/en/docs/runtime/testing#indicatorrelease ?. It tell exactly where to put it !!!

yes. If I apply to EA single currency like this, it work :

bool   hided=true;
int    TEMA;
//+-----------------------------------+
void OnInit()
  {
   TEMA=iTEMA(NULL,0,period,0,ApPrice)

   bool hidden=IndicatorRelease(TEMA);
   if(hided) Print("IndicatorRelease() successfully completed");
   else Print("IndicatorRelease() returned false. Error code ",GetLastError());
}

But if I apply to multicurrency like this, it not work

Hi achidayat,

This TradeSignalCounter() function, where do you call it ? IMHO, the indicator handle should be called in OnInit().

Hi achidayat,

I see ... thank you for the links -  my apology I missed that link earlier, maybe you should also post your questions on that code base and this article as well "Creating an Expert Advisor, which Trades on a Number of Instruments".

Regarding hiding indicator, maybe you should get those handle OnInit(), so IndicatorRelease() can works correctly - maybe.

:D 

[Mark Flint]

If you want to hide indicators created inside an EA, then before you create the handle for an indicator that you do not want to be shown during testing you need to tell the EA to keep the indicators hidden.  In MT5 this is done with the TesterHideIndicators() function call.

Maybe use something like this in your OnInit(), or just before your indicator creation:

   if(IS_DEBUG_MODE) // debug mode 

      TesterHideIndicators(false); // allow the indicators to be shown in Debug Mode

   else

      TesterHideIndicators(true); // hide the indicators at all other times

[Seyedbehrang Mousavi]

Hi,

How can I hide indicators in "visual mode" of back test in Mt5?
