MQL5: Expert Advisor not active after adding to chart via service-script

New comment
 

I use a service to open a chart and apply an expert advisor to it, but the EA stays inactive.

#property service
#include <fxsaber\Expert.mqh>

void OnStart()
  {

   MqlParam Params[1];
   string sec = "BTCUSD";
   int period = PERIOD_H1;
   Params[0].string_value = "Experts\\Advisors\\EA Studio Bitcoin H1 45207771.ex5";
   EXPERT::Run(ChartOpen(sec, period), Params);

  }

Automated trading is activated on all levels and works well if I drop the EA on the chart manually.

The service has the checkmark for "algo-trading"

If I go into the properties of the EA that got bound to the chart by my script, I can activate the "allow trading"-switch manually.

Who knows how that´s done via script?

cheers
