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)
