Get an Indicator's signal in an Expert

New comment
 

Hi there,

I am writing an Expert that is going to open trade on Buy/Sell signals (arrows) from Hull MA indicator

This is an example of my code:

double val = iCustom(_Symbol,PERIOD_CURRENT,"hull-moving-average-arrows",34,0,2,1,5,0,0,0,0,0,1,2,233,234,1,1,1);

But it always returns the market price.

How may I know if it's a sell or a buy signal?

Example of the indicator signals:

  1. Why did you post your MT4 question in the MT5 EA section instead of the MQL4 section, (bottom of the Root page)?

    Next time, post in the correct place. The moderators will likely move this thread there soon.

  2. Your iCustom call is bogus.

  3.       SetIndexBuffer(3,arrowUp);   
      SetIndexBuffer(4,arrowDn);
    Why are you not looking at the correct buffer indexes.

Thank you William,

I didn't notice I am posting my question in a wrong place. Thanks for the heads up. I'll pay attention the next time.

Also, thank you for your advice. I just noticed that the Indicator's source code is available and I could take a look.

I was trying a few indicators and most of them don't come with the source code. I'm still not sure how to read the signals from most of them. But I guess you solved my problem with this one :)
