Help Needed with iMA Function Parameter Error in MQL5
Hello everyone,
I am currently developing a custom indicator in MQL5 which utilizes multiple Exponential Moving Averages (EMAs). However, I am encountering a parameter count error with the iMA function and need some assistance in resolving it.
The code is intended to calculate four EMAs (5, 10, 20, and 60 periods) and check certain conditions to generate signals. However, when I attempt to compile the script, I receive the following error:
Here is the code:
ema5[i] = iMA(NULL, 0, 5, 0, MODE_EMA, PRICE_CLOSE, i);
ema10[i] = iMA(NULL, 0, 10, 0, MODE_EMA, PRICE_CLOSE, i);
ema20[i] = iMA(NULL, 0, 20, 0, MODE_EMA, PRICE_CLOSE, i);
ema60[i] = iMA(NULL, 0, 60, 0, MODE_EMA, PRICE_CLOSE, i);
Error (All 4 EMA facing same error):
'iMA' - wrong parameters count
built-in: int iMA(const string,ENUM_TIMEFRAMES,int,int,ENUM_MA_METHOD,int)
I have tried adjusting the parameters to match the iMA function signature but the error persists. I would appreciate it if someone could help me identify what I am doing wrong or suggest how I might correctly use the iMA function to avoid this error.
Thank you in advance for the help!
ema5[i] = iMA(NULL, 0, 5, 0, MODE_EMA, PRICE_CLOSE, i); ema10[i] = iMA(NULL, 0, 10, 0, MODE_EMA, PRICE_CLOSE, i); ema20[i] = iMA(NULL, 0, 20, 0, MODE_EMA, PRICE_CLOSE, i); ema60[i] = iMA(NULL, 0, 60, 0, MODE_EMA, PRICE_CLOSE, i);Those are MT4 calls.
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.
