Help Adding Indicator To Expert
Just curious as to how, I can add an indicator (i-trend) to an expert and create settings that if the indicator passes certain values in I-trend , to not enter a trade.
If can help or point me in right direction.
Thank youYou may look at Brainwashing EAs (1c or 1c1 or 1d versions) as an example. Beluck added this i_Trend with changable value.
iCustom is for you!

Thank youjpsdyb,
I think the best way is iCustom function:
Read this piece of one of my articles:
There are two kinds of indicators you can use in your code (Expert advisors, Custom indicators and scripts):
Built-in indicators:The MQL4 has a number of built-in indicators which you can use them in your code directly as a function for example:
The above code calculates the moving average indicator and returns its value.
The above code calculates the average true range indicator and returns its value.
Any other indicator:To use any other indicator in your code (I-Trend for example) you have to duplicate the code of this indicator in your code (it the hell way) or you can use the iCustom function:
What's iCustom anyway?
iCustom is a MQL4 function enables you to use external indicators in your expert advisor or custom indicator code without re-writing the code from scratch.
If you didn't have the code of the external indicator you want to use in your code iCustom is the only way to use the indicator in your code because iCustom works with the already compiled indicator (.exe4 format).
great! thank you

and how can I use the iMA function, not with a price, as the media of another indicator? like for example the media of RSI...
Thank you

Hi
Thank you for all the free info, it really helps a newbie like me a lot. I will appreciate it if you can explain the I icustom-function a bit more in detail. I try to put a function together for the attached indicators but must do something wrong. You will see that these two indicators do not have the same amount of info to be use in the icustom-function which still confuse me .I am not sure in what sequence to build the function . If possible can you post the icustom- function here and explain how you get to them.

I could not get the indicators to attached.I will post them here:

Hi
Yes it is the same indicators. Is there someone who can show me what the icustom-function of these indicators must be and a short explanation how to get there?
Thank youI do not know.
I know icustom, I know MACD but it is nothing in this indicator concerning "PRICE_CLOSE, MODE_SIGNAL" and so on.
there are many custom indicators and I have not been able to learn how to get them to be used on icustom
http://sufx.core.t3-ism.net/ExpertAdvisorBuilder/index.html
I would like to add a custom indicator to an EA and don't know how to do it without engaging someone who codes. I would love to be able to do it myself with some utility tool. any suggestions? instructions how to do it? I want to add the AutoCh indicator to these two EA's. So that it won't open positions if it gets too close to a support or resistance level.
