EA must run on open application...it's not server side scripting like TP or SL it's client side.. so you must keep your MT4 open all the time to see it works ================ Forex Indicators Collection |

Imagine the following. You opened Metatrader, opened one chart and attached one EA to this chart. Then you opened the other chart and attached the other (or the same one) EA to that "other chart". And both EAs opened the orders. Then one EA wants to modify the order but does not know which one should be modified. So, magic number is just a number which every trade is having. And EA can recognize easy which one should be processed. You don't need to do anyting with this manic numbers. When you see magic numbers' settings in EA so just use different numbers for every chart in one Metatrader. That's all. |
