Ok here you go Shelley really a great idea

This one handels trade by ticketnumber and knows after the part closes
automatic the new ticketnumer.
It is OOTB set to manage trades with the ticket number setting is
ManageByTickeNumber=true TicketNumber here you must input your ticketnumber you wish to manage(after partclose the trademanager knows automatic the new one and will use this automatic)
Attention make sure you have set ManageAllOpenTrades to false if you want to use other management options, as ManageAllOpenTrades overwrites all other settings !!
This version is OOTB set to ManageByTicketNumber with all partcose options activ, like Shelley wanted.
You can too select new
ManageByOrderComment and give an OrderComment
CommentOfOrder
for orders you want to manage, too in this case the trademanager will know after partclose(s) what order to manage.
A attach this version to to the first post as it is thanks to Shelley more functional!!
See first post for explaining all other functions

Cheers
