Hello MQL4 community,

Four digit broker: "3" is equivalent to 3.

Five digit broker: "30" is equivalent to 3.

Please confirm that the above two statements are correct.

Thank you.

Hello MQL4 community,

Four digit broker: "3" is equivalent to 3. //3 Point == 3 Pip

Five digit broker: "30" is equivalent to 3. //30 Point == 3 Pip

Please confirm that the above two statements are correct. // it is never 30 is 3 do you change 30 dollar for 3 dollar ??

Thank you.

"it is never 30 is 3 do you change 30 dollar for 3 dollar ??"

No. :)


When coding a SL in an EA for a five digit broker, "30*Point" is equivalent to 3 points.

When coding a SL in an EA for a four digit broker, "30*Point" is equivalent to 30 points.

Please state otherwise if this is incorrect.

Thank you.

Adjust for points/pips on stops AND slippage

//++++ 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(){                                             OptInitialization();
     if (Digits % 2 == 1){      // DE30=1/JPY=3/EURUSD=5 forum.mql4.com/43064#515262
                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());

@WHRoeder:

If what I wrote is correct, then all the code in "SRC" can be simplified.

Example:

int  TP=50;
int  SL=50;
int  slip=3;
bool 4digit;
bool 5digit;

if(4digit)

  {TP*1; SL*1; slippage*1;}

if(5digit)
 
  {TP*10; SL*10; slippage*10;}

Thank you.

Your code will not work . . . what does this do ?

{TP*10; SL*10; slippage*10;}
 

int TP = 50.

50*10 = 500.

500 = 50 for a 5 digit broker. The multiplication of 10 to the number will add a zero to the end of the number.

I believe that it would work. Why would it not?

Maybe this would make more sense...

{TP=TP*10; SL=SL*10; slip=slip*10;}

Thanks Simon.

Yes it would and it would compile and change the values. Alternatively you could just spend some time to understand WHRoeder's code and use that . . .


If you use your code you need to be careful that it isn't executed more than once at ant time including when changing chart timeframes . . . . . otherwise slip goes from slip to slip*10 to slip*100 to slip*1000, etc
 

I will spend time to understand WHRoeder's code.

Thank you.
