Can an Indicator run an EA

Anyone know if its possible to trigger an EA from an indi? (not adding or converting indicator to an EA).

eg everyone knows an indicator can paint and arrow/line/dot etc onto a chart but can it possibly make an external call to an EA or anything of that nature?

Thanks in advance..

Not directly.

Let's say an indi paints an arrow object on the chart, the EA would find that arrow, interpret the instructions inside, and then execute them. As far as direct calls, I don't think so.

EAs and indicators can easily communicate.

Here's a good thread that shows how to do this using iCustom.

It's possible to do your calculations using an indi and then use the results on your expert to execute trades. e.g You could have a library which sends the results of your calculations to your given indi.... the very same library could be used by your expert to execute your trades.

hey gman..... we would need to know just what make an external call would be required to do.....

both indicators and experts attached to other charts can set global variables which can trigger actions in other ea's....

the picture show the patience ea is setting the patience global variable.... and on another chart the tsr indicator is setting the tsrbuy global variable....

the tsrbuy will trigger a buy order in another ea..... and the patience reading of -50 or lower will trigger a sell.....

not sure if that would be a solution for your situation........h

Thanx for your responses everyone.

Basically what I mean by "make an external call" would be something like running an existing EA. Same as in cmd files running other executables etc. So when an indicator generates a signal, it also runs an existing EA.
