MT4 to MT5 translation problem

[tshadgett]

Hi, 

I'm getting different behaviour in MT5 when I translate the following code:

MT4:

int recentLow = iLowest(Symbol(),PERIOD_CURRENT,MODE_LOW,5,0);
double stopLossPrice = Low[recentLow]-(iATR(Symbol(),PERIOD_CURRENT,14,0)/2);

MT5:

int recentLow = iLowest(Symbol(),PERIOD_CURRENT,MODE_LOW,5,0);
double atrGap = iATR(Symbol(),PERIOD_CURRENT,14)/2;
double stopLossPrice = Low[recentLow]-atrGap;

For some reason, I do not get the same resulting value in stopLossPrice.

Could anyone please provide some pointers where I might be going wrong here?

Thanks

In MQL5, the indicator functions do not return buffer data values as you do in MQL4. They return an indicator handle (an int, not a double).

You then have to use that handle with the CopyBuffer function to obtain the buffer data values. Study the example code provided for the iATR function.

int iATR(
   string           symbol,        // symbol name
   ENUM_TIMEFRAMES  period,        // period
   int              ma_period      // averaging period 
   );

Return Value

Returns the handle of a specified technical indicator,  in case of failure returns INVALID_HANDLE. The computer memory can be freed from an indicator that is no more utilized, using the IndicatorRelease() function, to which the indicator handle is passed.

Thanks Fernando,

Appreciate you pointing me in the right direction!
