Yes. The EA have to run non-stop.
Another test with GBP/USD
The same here Michael. Your settings are very high risky. If you test at beginning of the year 2018 your account crashed several times.
Another question, if we use the EA with different pairs at the same time, do we have to use different magic numbers for each EA and pair?
...for different? No.
I just read your code, well, it's interesting, but still, I do not understand the logic of your EA.
Can you explain me in a few lines ?
thank in advance
