error: event handling function not found

I would like to include this expert advisor into an other one, which is why I don't use the OnTick() function there. But what else am I supposed to use? Why can't this just be the definition of a function, that I would only call in an other expert advisor?

Thanks

It is just the definition of a function. As such it is not an EA.

Put the code in an EA and call your function in an event handling function. Or make that file an include file and include it in your EA.

Thank you, I did not know about the Include file format.
