write value to a file?

Hi:
I have two working programs, an EA and an indicator. I've been trying to merge them and the more I learn, the bigger the task seems. A local programmer has taken a stab at it, but when combined, the looping mechanism in the indicator part is not working properly.

I really only need one value from the indicator and I want to be able to use it inside the EA. The value is always either 1 or -1.

It has occured to me the simplest way to accomplish this might be to have the indicator write the value to a file, then have the EA read the value. If someone knows how to do this I would love to hear from you. Maybe someone has some sample code that does this?

Thanks,

John

What you suggesting will work, but it seems like a clunky way of doing things and depending on timing could result in wrong answers. That is if the value in the file is written and read and changed and not reread.

There is no messaging support in MQL4, so I guess that leaves you with using a global value. You should refer to MQL4.com to get an explanation and examples.

hey john..... i rewrote your indicator..... see your other thread.....h
