Master EA trying to prioritize and rotate 28 Slave EA's

xazarlx20 2021.06.12 19:02

I have had no luck with MUTEX so I thought this might work. I wrote a ''Master" ea that cycles through my 10 preferred symbols three times each before moving on to the 18 lesser symbols.

The code writes to a global variable every half a second, each time representing the next symbol in the hierarchy. When on of the "Slave" EA's has in incoming tick it checks to see if the global variable matches the symbol. If so the code is run, if not the code returns.

I know this is a system full of holes but I don't want the EA's placing more trades than the four that I want as a limit.

Here is the "Master" and "Slave" code:

Any feedback would be appreciated.

“no luck” is meaningless — just like saying no luck with the car. Doesn't start, won't go in gear, no electrical, missing the key, flat tires — meaningless.

Which part of "No Luck" is meaningless to you? Each of those words have meaning and together they also have meaning. Maybe it is the reader who is devoid of meaning?

Speaking of meaningless ... The code you pointed to, "Mutex.mqh", is meaningless to me, especially without the dependencies called for in it's header. Maybe nice code if it was complete.
