EMA values MT4 vs MT5

[Davide Gribaudo]

Hello, 

I just moved from Mql4 to Mql5.

How to get MA value of the last Candle on MT4:

double  iMA(symbol,timeframe,ma_period,ma_shift,ma_method,applied_price,shift);

so I need:

double ema3 = iMA(_Symbol,_Period,3,0,MODE_EMA,PRICE_CLOSE,1);

What I need to get this exact value on a MT5 EA?

Why on MT4 is enough a line of code and on MT5 I need dozens?

That is incorrect! iMA() returns a handle in MQL5, not a value. Only in MQL4 did it return a value, but you are coding in MQL5. Please read up on the documentation and have a look at the example code.

In essence, you should obtain the handle in the OnInit() and then use CopyBuffer() in the other event handlers such as OnCalculate().

Perhaps you should read the manual, especially the examples.

They all (including iCustom) return a handle (an int). You get that in OnInit. In OnTick/OnCalculate (after the indicator has updated its buffers), you use the handle, shift and count to get the data.
