What does it do exactly?
Very simple, as its name suggests, you can perform a trade on your Ninja Trader chart and have that same trade executed on other accounts simultaneously.
What to use it for?
You can trade with your personal account and at the same time trade, for example, on a funded account. Or you can have a funded account, want to get another one, and do an evaluation without giving up trading with your regular account. In short, what you do with one account, you can repeat it on another without any problems.
Does WINBANCE allow it?
At WinBance it is only allowed to use it in evaluations, we have the Replicator for our clients free of charge when purchasing more than 4 accounts.
