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.

Good day, I am not sure if the intend is to help or crush me.
I have read the manual, but my skills are at this level. I need to guide me, for now i am over charged by all your links.
If you can/want to help me more, I will be grateful.
Regards
here i am so far, and i really not know/understand why the print result is not the last fractal value.
Can someone help me please?

If you don't understand…
But i tried so many way with iFractals with no success. Even with IndicatorCreate... I really do not understand. I am not so skilled, but i am not a beginner anymore.
Here is my code. At my knowledge, all is well declared and used (?) and the expert journal give me "false" result.
#property indicator_chart_window #property indicator_plots 0 //+--- fractals int USD_ind_fractal; //+--- fractal UP int USD_fractal_UP_handle; double USD_fractal_UP_buffer[], USD_fractal_UP_copy[], USD_fractal_UP; //+--- fractal DN int USD_fractal_DN_handle; double USD_fractal_DN_buffer[], USD_fractal_DN_copy[], USD_fractal_DN; int OnInit() { USD_ind_fractal=iFractals("GBPUSD",PERIOD_M15); //+--- fractal_UP ArraySetAsSeries(USD_fractal_UP_copy,true); CopyBuffer(USD_ind_fractal,UPPER_LINE,0,1,USD_fractal_UP_copy); USD_fractal_UP=USD_fractal_UP_copy[0]; /* */ //+--- fractal_DN ArraySetAsSeries(USD_fractal_DN_copy,true); CopyBuffer(USD_ind_fractal,LOWER_LINE,0,1,USD_fractal_DN_copy); USD_fractal_DN=USD_fractal_DN_copy[0]; /* */ PrintFormat("fractal DN : "+(string)USD_fractal_DN); PrintFormat("fractal UP : "+(string)USD_fractal_UP); //+--- return(INIT_SUCCEEDED); }#property version "1.00"
int OnInit() { USD_ind_fractal=iFractals("GBPUSD",PERIOD_M15); //+--- fractal_UP ArraySetAsSeries(USD_fractal_UP_copy,true); CopyBuffer(USD_ind_fractal,UPPER_LINE,0,1,USD_fractal_UP_copy);
So i tried another way from your link but with the same wrong result. (compilation is ok)
Could it be possible that its just a bug from mt5, as i always succeed to get value with the others indicators (iMA, iMACD...etc)?
my failed attempt code.
double iFractalsGet(const int index) { double Fractals[1]; //--- reset error code ResetLastError(); ArraySetAsSeries(Fractals,true); //--- fill a part of the iFractals array with values from the indicator buffer that has 0 index if(CopyBuffer(USD_ind_fractale,0,index,1,Fractals)<0) { //--- if the copying fails, tell the error code PrintFormat("Failed to copy data from the iFractals indicator, error code %d",GetLastError()); //--- quit with zero result - it means that the indicator is considered as not calculated return(EMPTY_VALUE); } return(Fractals[0]); }
iGetArray doesn 't work in OnCalculate().

You are almost there, remove "CopyBuffer" from the OnInit() section of the code, within this section there is no candle values to copy, hence the reason you are asked to do that in the "OnCalculate/OnTick"
yes, i already tried to do it with copybuffer in OnCalculate(), but the result is always wrong.
That's why i ask if a native bug could be possible, because, with others indicators, it works fine with all the code in OnCalculate().
Nb: you re wright, thank God for everithing!
USD_sma_fast_handle=iMA(USD_paires[v],enum_ut_mt5_6_col[h],sma_fast_prd,shift,MODE_SMA,PRICE_CLOSE); ArraySetAsSeries(USD_sma_fast_copie,true); CopyBuffer(USD_sma_fast_handle,0,0,1,USD_sma_fast_copie); USD_sma_fast=USD_sma_fast_copie[0];
But does not work with iFractals and UPPER_LINE.

I am working on a personnal screener project with the fractals.
I need to know if the current price is above the last up fractal, or below the last down fractal or flat.
i have made this code, and my screener reacts with colors, but the result is totally wrong.
Can someone heavily help me please ?
