iCustom
Hello everyone.
For a while now, I have been trying to learn how to use iCustom. I have limited sources and I get stuck quite often.
I really need a workaround on how to let my EA know when a buffer plots an arrow, or detect the colour change.
A sample code will be highly appreciated.

It's simple. An example based on the Two Rivers Alert custom indicator. The indicator has two buffers ("Up" and "Down") - when an signal appears in the buffer, an arrow appears. How to check: is there a signal or not? Very simple:
- if there is a signal "arrow" - then the price is in the indicator buffer
- if there is no signal, then the value “0.0” is in the indicator buffer. The value "0.0" is used in this indicator, for this you need to look
at the indicator code:
for(int i=limit; i<rates_total; i++) { //Если есть сигнал к покупке(Свеча пересекла полностью) - поставим синюю стрелку вверх if(open[i]<=iMALowBuffer[i] && close[i]>iMAHighBuffer[i] && close[i]>open[i]) { UpBuffer[i]=high[i];//запомним цену синей стрелки if(prev_calculated!=0) { if(time[i]!=m_last_notifications) { m_last_notifications=time[i]; Alert("Up Alert"); } } } else UpBuffer[i]=0.0; //Если есть сигнал к продаже - поставим красную стрелку вниз if(open[i]>=iMAHighBuffer[i] && close[i]<iMALowBuffer[i] && close[i]<open[i]) { DownBuffer[i]=low[i];//запомним цену красной стрелки if(prev_calculated!=0) { if(time[i]!=m_last_notifications) { m_last_notifications=time[i]; Alert("Down Alert"); } } } else DownBuffer[i]=0.0; } //--- return value of prev_calculated for next call return(rates_total); }

Advisor example:
For Indicators I don't have source code for
I like to open my MT terminal ctrl+D for data window then check how many buffers I am dealing with then identify my budget of interest.
Then I look at the input parameters for the indicator, and I note all the parameter settings and their values, then I write my iCustom function
NB: Will post Code Here I'm using Mobile and can't insert it using the Code tool.
MT4
double indicatorValue = iCustom(m_symbol, timeframe, path,/* [Parameters noted above separate by comma (,) ]*/,buffer_number,shift);
MT5
Oninit
Int IndiHandle = iCustom(m_symbol,timeframe,path,/* [Parameters noted above separate by comma (,) ]*/);
OnTick
int copy = CopyBuffer( IndiHandle ,buffer_number,0,count, indicatorValueArray);
Though I hv never worked with MT5 lol

Thank you. I work with mt5 only. I found a work around for working with iCustom, thanks to Vlamidir Kaputov. Been practicing with different Indicators and using comments to figure out the output of each buffer. I'm learning great!

Thanks a lot, i really appreciate. i used the above example of iCustom EA to call my custom indicator but its failing to execute trades. May i kindly have solution in execution if possible thanks

You are testing against zero. Does the indicator use zero for empty instead of EMPTY_VALUE?
