Metatrader EA stops trading after entering one trade?

Hi.

I am very new to EA's.

I am trialling three simple EA's (created by others) in Metatrader 4. After opening one trade, all three EA's will stop taking trades. I don't know whether this is standard Metatrader behaviour, or specific to these EA's.

I like it that Metatrader stops trading after one trade entry, but would like the option to manually reset the EA so that it will take additional trades. Is this possible? (I don't want the EA to manage any trades after entry; I will manage the trade manually.)

I also wonder about the magic number. I would like to use the same EA on multiple pairs. Do I need to enter a different magic number for the EA on each pair's chart? Does the fact that I only want the EA to enter trades, not manage them, affect the answer?

Thank you.

Your ea’s are most likely coded to open a trade if no others exist for the symbol. Yes it is possible to allow the ea to reset like you say but it would only work on whichever ea’s code was modified. If you want to use the ea on multiple pairs but only for entries and you are manually managing trades then you don’t need a magic number.

Do you own the source code of that EA? if yes, it could be changed to enter additional trades even if it finds others that are open.

Thank you for your responses, guys. I apologise for the long delay in offering my thanks; I misplaced the link to my post and have only just found it again.

Kind regards,
