Separate string by comma

New comment
 

Hello,

Planning on using multiple orders:

extern string TP="18,46,72";

How do I separate this into int variables?

Hoping to have room for unlimited int variables so how

can I find the number of orders and the individual int values?

THX

 

Hello,

I found an include at Forex Factory that has what I was looking for however I don't know how to call it.

#include <HandyUtilityFunctions.mqh> http://www.forexfactory.com/attachment.php?attachmentid=651955&d=1299014907

extern string TP="18,46,72"; 

//+----------------------------------------------------------------------------+
//| int StrToIntegerArray(string str, int &a[], string delim=",", int init=0)
//+----------------------------------------------------------------------------+
// Breaks down a single string into integer array 'a' (elements delimited by 'delim')
//  e.g. string is "1,2,3,4,5";  if delim is "," then the result will be
//  a[0]=1   a[1]=2   a[2]=3   a[3]=4   a[4]=5
//  Unused array elements are initialized by value in 'init' (default is 0)
//+----------------------------------------------------------------------------+
int StrToIntegerArray(string str, int &a[], string delim=",", int init=0)
{
        for (int i=0; i<ArraySize(a); i++) 
                a[i] = init;
        int z1=-1, z2=0;
        if (StringRight(str,1) != delim)  str = str + delim;
        for (i=0; i<ArraySize(a); i++)  {
                z2 = StringFind(str,delim,z1+1);
                a[i] = StrToNumber(StringSubstr(str,z1+1,z2-z1-1));
                if (z2 >= StringLen(str)-1)   break;
                z1 = z2;
        }
        return(StringFindCount(str,delim));
}

Hello,

I'm trying to get prices for trailingstop-start, takeprofit, and stoploss from modifying the integer array by multiplying it by a double point and

I don't get a double price which I would need to add or subtract from the market price.

Could I just put the array & point equation in the order?

Like: OrderSend(Symbol(),OP_BUY,1,Ask,3,SLarray[SLslv]*UsePoint-Ask,TParray[TPtpv]*UsePoint+Ask,"My order #2",16384,0,Green);

Here's my code:

   { 
   double UsePoint; if(Digits==2||Digits==3) UsePoint=0.01; else if(Digits==4||Digits==5) UsePoint=0.0001;
   //----UPDATE INPUT PARAMETERS
   //---Split strings(identify numbers from strings)
   int TSSorders = StringFindCount(TSS,",") + 1; int TPorders = StringFindCount(TP,",") + 1; int SLorders = StringFindCount(SL,",") + 1;
   //---Create Array(convert strings into arrays)
   int TSSarray[]; int TSSA = ArrayResize(TSSarray,TSSorders); int tsto = StrToIntegerArray(TSS,TSSarray); for(int tsta=0; tsta<tsto; tsta++) //Print(TSSarray[0]+" "+TSSarray[1]);
   int TParray[]; int TPA = ArrayResize(TParray,TPorders); int t = StrToIntegerArray(TP,TParray); for(int p=0; p<t; p++) //Print(TParray[0]+" "+TParray[1]+" "+TParray[2]);
