Hello Tom,

Thanks for your post and welcome to the forums.

To add to a position using NTDirect.DLL, use the place command.

In the description of the Place command, "...To apply an order to an active ATM Strategy (existing strategies Stop Loss and Profit Target orders are amended) pass in the active strategy ID value and leave the strategy name field blank."

Here is a link to the help guide: http://www.ninjatrader.com/support/h...parameters.htm I quoted from the 3rd section on that page.

Please let me know if I can be of further assistance.

thanks for your quick reply. i meant to add to an existing long/short position. e.g:

1 long @ 152.10 (stop @ 152.03 / target 152.20) <= the entry is already filled
(_ntClient.Command("PLACE", "Replay101", _symbol, "BUY", 1, "LIMIT", px, 0, "GTC", "", atX, strategyX);

now i would like to add another 3 contracts to strategyX. this works with the PLACE command but allows for multiple entries. i was looking for some way to avoid this by using an orderId like 'Entry2' or such. so that it behaves like 'Entry' (which i can fire as often as i want without placing additional orders).

Hello Tom,

Thanks for your reply.

You would need to manage the ordering with your code/logic

Something along the lines of a check to see you are long and have not yet added and the conditions are right to add, then add and set a flag to say you have added so that you only do that once. When you are flat you would reset the add flag.
