Hello All,

I am still hoping someone here has much knowledge of MQL4 and can please help me program this idea.

If you place for example an MACD oscillator on an MT4 chart, you can then apply another indicator (example: Moving Average- purple) to the MACD. You can then apply another indicator (example: CCI - yellow) to the Moving Average of the MACD.

I know you must use arrays etc. to program this in an EA, but I have'nt been able to do this successfully.

Maybe someone could please help me.

Please see the attached picture of what I'm trying to do.

I would like to use the final indicator (the CCI indicator in the example above) to open buy/sell positions in an EA

Thanks for your time,

Andre

Hi!

This should do it.

If you need modifications or help just give me a call

Hi there Parmenides,

I also sent you email, as per below....


Thanks again for your help on the MQL Forum regarding the indicator below.

Just two questions:

- Can I use Weighted MA rather than SMA ?

- How do I use the final signal of this indicator, i.e. the "CCI" signal in an Expert Advisor? How would I BUY if the CCI signal goes from below zero (negative) to above zero (positive)? And also the other way round, how do I SELL when the final CCI signal goes from postive to negative?
.....or How do I call this indicator in and EA and use the CCI signal for BUY and SELL orders

Your help is much appreciated,

Best Regards,
Andre
