NormalizeDouble problem

New comment
 

Hi everyone,

why in the name of god do


a=NormalizeDouble(Point,Digits);

Alert(a);


returns 0 ??? It should return Point value for that instrument i.e. EURAUD = 0.00001 etc.


Yeah I know I can use DoubleToStr .. actually that DOES returns the right value but I can't work with string, right? What I'm actually up to is set T/P to High+80*Point


Any suggestions?

 

a should be a double

 
it is ofc
 

string a= DoubleToStr(Point,Digits);

Alert(a);

OrderModify(OrderTicket(),OrderOpenPrice(),OrderStopLoss(),OrderOpenPrice()+80*Point,CLR_NONE);

As I keep telling people . . read the Documentation, Alert()

"Data of double type output with 4 decimal digits after point." so what do you get when you take the first 4 decimal digits of 0.0000 1 well . . . 0.0000 . . . it's a display issue.

Please get rid of the NormalizeDouble . . . you don't need it in this case.

 
  1. Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 forum
  2. Can price != price ? - MQL4 forum
  3. Use DoubleToStr in Alert or
    string  PriceToStr(double p){   return( DoubleToStr(p, Digits) );              }






 
deVries:

string a= DoubleToStr(Point,Digits);

Alert(a);


OrderModify(OrderTicket(),OrderOpenPrice(),OrderStopLoss(),OrderOpenPrice()+80*Point,CLR_NONE);


I don't know why.. but it actually works now with your suggested OrderModify.

To compare, my OrderModify for long pos. looked like this:

OrderModify(OrderTicket(),OrderOpenPrice(),OrderStopLoss(),a+b*point,CLR_NONE);

where:

a = NormalizeDouble(iHigh(Symbol_Of_Order,0,0),Digits);

b = MarketInfo(Symbol_Of_Order,MODE_STOPLEVEL);


Again, IDK why my solution didn't work but thank you anyway it's ok now.


EDIT 2 hrs later: No it's not working :-) EURAUD open price was 1.21286 and it changed T/P to 2.01286 even though I used above deVriese's OrderModify.

So basically it adds 0.8 (instead of 0.00080 that it should) to the openprice.


Well 

OrderOpenPrice()+80*Point

doesn't work either, does it?

Since somehow it replaced Point value with 0.1

how come?

Then try it this way

OrderModify(OrderTicket(),OrderOpenPrice(),OrderStopLoss(),OrderOpenPrice()+(80*point),CLR_NONE);
but remember if you do this ordermodify for a 5 digits symbol (EURAUD) on a 3 digit chart (like EURJPY)

then it will be pointvalue 3digit chart = 0.001 and 5 digit chart point is 0.00001

So if you modify a trade this way on a chart with other pointvalue it will go wrong

use then also.....

double point =MarketInfo(Symbol_Of_Order,MODE_POINT);   //point now used in ordermodify instead of Point

to get right pointvalue

to avoid the possibillity to count up 1.21489 + 80 * Point = 81.21489 * Point

I set it now to

OrderOpenPrice()+(80*point)
