Executed contract number doubling

[srbdoc]

Using an ATM strategy with 1 contract. With 1 contract active I enter an additional position and the number of contracts increases to 2 - fine. But if I enter a 3rd position the number of contracts doubles to 4. How do I prevent this and add positions with only 1 contract?

Looking at it further the execution of additional contracts seems to be random. With a single contract ATM strategy adding an additional position might change the active contract number from 5 to 7 with a single click.

Hello srbdoc,

Thank you for your post.

This is due to the setting of the 'ATM strategy selection mode'. After your first trade, the ATM menu may display a lightning icon, which means that the active ATM is selected and orders when scaling in will be merged with the existing ATM orders.

You will need to re-select your ATM strategy before submitting your second entry order to resolve.

You can also set 'ATM Strategy selection mode' to 'Keep Selected ATM Strategy Template on Order Submission'. That way, you do not need to re-select your ATM strategy before submitting your second entry order. After you submitted your first entry order, 'the 'ATM Strategy' drop down menu will automatically keep your initial ATM strategy selected - it does not turn to '* Active ATM Strategy # - name'.

Please right click in the SuperDOM and select 'Properties' to configure the 'ATM Strategy selection mode' setting. More information can be found at the link below.
