Need a trade copying EA

I need a trade copier EA that will copy trades from my master account to other child accounts. The trade copier will open all orders from the master account to the child accounts. The EA will also close partial orders when partial close of orders is done from the master account. The EA will have a percentage multiplier for the child EA where when this is adjusted it will open the proper order lot size for the account size so this field needs to be changeable. If SL or TP is adjusted on master it will change these on the child accounts. So basically activiley mirroring the master account at all times.
