Hi ags,

I can just guess, but the current implementation triggers Zorro on every tick it receives, for any asset in the asset list.
This helps in receiving "real time" ticks and you do not lose any ticks in between BrokerAsset calls.
I can implement a configurable parameter were you can disable the "real time" behavior.
I don't know if the other plugin implements SET_HWND, so can not tell about it.
Keep you updated when done with the adaptation.

EDIT: The real problem here is with Zorro, as you can not stream incoming data directly. This would reduce the amount of work drastically.
