My EA doesn't update its information.

[Graham Pace]

In my EA I have it pulling the Ask and bid from different pairs (other than the one it is attached to) but once it pulls the information it never updates it. How do I make it so my EA always has the current bid and ask prices from other pairs?

[Christian Anton Schluessel]

I'd suggest using a timeer that reads the bid as ask every millisecond and saves it into a global variable.

for the time check here:

https://docs.mql4.com/eventfunctions/eventsetmillisecondtimer

// we're ob the DJ-chart and wnt to read eurusd bid & ask
double bid_eurusd = 0.0;
double ask_eurusd = 0.0;

int OnInit()
  {
//--- create timer
        
   // set timer between 1 and 10 milliseconds        
   EventSetMillisecondTimer(1); 
//---
   return(INIT_SUCCEEDED);
  }


void OnDeinit(const int reason)
  {
//--- destroy timer
   EventKillTimer();
  }

// gets invoked every millisecond
void OnTimer()
  {
//---
        // asuming we're on the DJ-chart lets get EURUSD bid and ask    
        bid_eurusd = MerketInfo("EURUSD", MODE_BID);
        ask_eurusd = MerketInfo("EURUSD", MODE_ASK);
   
  }
