Renko123,
a) The current version of my Trade Copier copies only positions from one account to another in same instance or multiple instances of Sierra.
b) Copying of the trailing stops and targets orders is under development pending for some enhancements in ACSIL functions. Request you put in your support for the requested changes in the thread - https://www.sierrachart.com/SupportBoard.php?ThreadID=68241

Does this tool also adjust the trailing stops and targets of the follower accounts during an open trade when the leader account is adjusted?

Yes. It also converts futures trades to long Retirement Trades, supporting inverse ETFs.

Hi, can anyone who has a sierra chart trade copier please contact me because I can not send PMs as long as it can solve this issue:

I need one which copies between two or more instances. There should be a sender and multiple receiver, i.e. via a tag.

Also when I enter an order with multiple OCO groups, e.g. 2 groups, both TP/SL orders should be synced to the receivers and updated when changed on the sender.

Thanks!
