Certain Currency pairs display values to 5 decimal places (EURUSD), others 4 and so on. I wrote the code below to return the integer value of the decimal places minus one. This function just takes into consideration a few pairs. I would like to expand it to cater for all pairs. How can I find the number of decimal places for each Symbol() price?
int decimalPlacesForPairs() {
if ((_Symbol == "XAUUSD") || (_Symbol == "USOIL")) {
return 1;
}
else if (_Symbol == "CADJPY") {
return 2;
}
else return 3;
}

In MQL4 you have access to a predefined variable
int Digits
. This function returns the number of digits after the decimal point.
The example given is:
Print(DoubleToStr(Close[0], Digits));
Another way, and perhaps a better way in your case is to use
MarketInfo
. Here you can return the number of decimals places per symbol by inserting the symbol as a string variable.
The example given:
int vdigits = (int)MarketInfo("EURUSD",MODE_DIGITS);
In your case you could have a function like the below:
int decimalPlacesForPairs(string sPair) {
return MarketInfo(sPair),MODE_DIGITS);
}
And to call from your
Main(){}
:
void Main()
{
decimalPlacesForPairs(Symbol());
//or
//decimalPlacesForPairs("EURUSD");
}

Place your Digits or Pips in the global area.
double pips;
double ticksize = MarketInfo(NULL,MODE_DIGITS);
if(ticksize==2||ticksize==3||ticksize==4||ticksize==5)
pips=ticksize*10;
else pips =ticksize;

The only ones that aren't 5 decimals are yen pairs right? Just do a string search to see if it contains yen.
string pair="USDJPY";
if(StringFind(pair,"JPY",0)>0)
{
//Do stuff with 3 decimals
}
else
{
//Do stuff with 5 decimals
}
Or this will do it for you
string pair="USDJPY";
double onePip = MarketInfo(pair,MODE_POINT)*10;
double fourPips = MarketInfo(pair,MODE_POINT)*40;
note: the last integer in the function is how many pips you want in points (which are 1/10th of a pip)
