Link: Indicator and EA

New comment
 

Hi,


I would like to know how it's possible to link indicator and EA: what is the code in the EA ?


Shoud the indicator has to run on the chart where the EA is running or it s not necessary ?


One indicator can run or be called by two different EA ?


Many thanks

Not necessary.

1. See iCustom() function.

2. The indicator is accessed directly by the EA with the iCustom() function. The only thing you need is the actual indicator in (ex4) your experts/indicators folder.

3. Going with logic and referring to #2, yes.. An indicator can be called by a gazillion EA's if you have a powerful enough PC. It's not a shared resource but rather executed when requested.

OK, so i can have some computational capacity constraint on this.

please anybody can help
i tried to use (at_Itp4_Env indicator) for EA, what parameters in ICUSTOM i have to write to send order to upper line and other order to lower line?

at_itp4_env.mq4  4 kb
 

SetIndexBuffer (0, UperBuffer);
SetIndexBuffer (1, ci);
SetIndexBuffer (2, DownBuffer);

.

Those are the buffers.. If you want the value of the upper line, specify index 0. If you want the value of the lower line, specify index 2 in iCustom().
