question on ordersend error 138

[[Deleted]]

Hi Pros,

When I test the EURUSD history data, there is no error:

OrderSend(Symb,OP_BUY,0.2,Ask,2,SL,TP);

When I live trading, it always reports error 138. It still opens the order but reduce the lots from 0.2 to 0.12.

Could anybody tell me why this is happening? Should I make the slippage parameter larger to avoid this?

Thank you so much

On a 5 digit broker your slippage of 2 means 0.2 pips. EA's must adjust TP/SL, AND slippage.

//++++ These are adjusted for 5 digit brokers.
int     pips2points;    // slippage  3 pips    3=points    30=points
double  pips2dbl;       // Stoploss 15 pips    0.0015      0.00150
int     Digits.pips;    // DoubleToStr(dbl/pips2dbl, Digits.pips)
int     init(){
    if (Digits == 5 || Digits == 3){    // Adjust for five (5) digit brokers.
                pips2dbl    = Point*10; pips2points = 10;   Digits.pips = 1;
    } else {    pips2dbl    = Point;    pips2points =  1;   Digits.pips = 0; }
    // OrderSend(... Slippage.Pips * pips2points, Bid - StopLossPips * pips2dbl

Show your code otherwise we have to guess . . .

Yes I am using a 5 digit broker.

If I increase slippage to 10, it would work, right?

Thank you!

But why does the metatrader reduce my 0.2 lot to 0.12 lot, when the error 138 happens. This wierd...

Only explanation I can GUESS at is that your code is changing the lot size . . . . best I can do.
