How do trades get to ATAS from another trading platform?

All trades are stored on a server that has statistics on trades from your trading account, therefore, no matter where you open them, they will be available from any platform if your account is connected to it... (at least this is how it should be). If you did not connect your account in ATAS, then you connected Ninja to ATAS. For example, you may have general Rhythmik quotes (it provides not only quotes, but also trading and statistics). But we recommend that you make all trading operations from only one platform.
