Printing Excersise

New comment
[Deleted]

From the Expert Adviser Wizard, I have selected custom indicator and only put this print line on it. I dropped it on a chart which has an EA running and a trade progressing opened by that EA. I got nothing printed on the chart. Is it because of the magic # or something else? Can you tell me what I can do to make it print the total number of opened and pending orders?

int start()
  {
   Print (OrdersTotal());
   return(0);
  }

Thanks,

Print doesn't print to the screen it prints to the Experts tab (Journal tab if running in the Strategy Tester) https://docs.mql4.com/common/Print if you want to "print" to the screen try Comment : https://docs.mql4.com/common/Comment or if you want to control the position use Objects : https://docs.mql4.com/objects

I have a demo account with a 5 digit broker, and been trying to print the ask and bid on the chart. When I code

Comment(Ask, " ", Bid);

I get the numbers rounded to 4 digits, but when I code

Comment(Ask + " " + Bid);

I get them rounded to 8 digits! and the last 3 digits of them are 0s.

What's the right or standard syntax in which we print stuff in mql?

Regards,

tapo

Use https://docs.mql4.com/convert/DoubleToStr

Comment("Ask: ", DoubleToStr(Ask, Digits), " Bid: ", DoubleToStr(Bid, Digits));

Print/Alert/Comment defaults to 4 digits. You must adjust for 4/5 digit brokers.
string  PriceToStr(double p){ return( DoubleToStr(p, Digits) ); }
//or
string  PriceToStr(double p){
    string pFrc = DoubleToStr(p, Digits);       if(Digits.pips==0) return(pFrc);
    string pPip = DoubleToStr(p, Digits-1);
    if (pPip+"0" == pFrc)       return(pPip);           return(pFrc);          }
//with
//++++ These are adjusted for 5 digit brokers.
int     pips2points;    // slippage  3 pips    3=points    30=points
double  pips2dbl;       // Stoploss 15 pips    0.015      0.0150
int     Digits.pips;    // DoubleToStr(dbl/pips2dbl, Digits.pips)
int     init(){
     if (Digits % 2 == 1){      // DE30=1/JPY=3/EURUSD=5 https://www.mql5.com/en/forum/135345
                pips2dbl    = Point*10; pips2points = 10;   Digits.pips = 1;
    } else {    pips2dbl    = Point;    pips2points =  1;   Digits.pips = 0; }
    // OrderSend(... Slippage.Pips * pips2points, Bid - StopLossPips * pips2dbl
//---- These are adjusted for 5 digit brokers.
    /* On ECN brokers you must open first and THEN set stops
    int ticket = OrderSend(..., 0,0,...)
    if (ticket < 0)
       Alert("OrderSend failed: ", GetLastError());
    else if (!OrderSelect(ticket, SELECT_BY_TICKET))
       Alert("OrderSelect failed: ", GetLastError());
    else if (!OrderModify(OrderTicket(), OrderOpenPrice(), SL, TP, 0)
       Alert("OrderModify failed: ", GetLastError());

Hi guys,

I added the following block of code to an EA and backtested it. I can find neither the log file nor tester\files folder!!

Can you help?

   int handle = FileOpen("Log.txt", FILE_CSV|FILE_WRITE, ';');
   if (handle > 0)
   {
      FileWrite(handle, Close[0]);
      FileClose(handle);
   }

check if there is some error

if (handle < 0) Print ("Error Opening File");

to avoid filling my Expert tab with printings, I put the following line within the if statement and got the the sentence printed on the chart all the way through the backtest

Comment("handle is greater than 0.");

that means there was no error. The strange thing is that I'm not finding the tester\files folder in the first place. It's not only the file which is missing.
