I was poking around the platform and think I’ve found a solution to my worries.
Under ‘Settings’ you can edit the rules for each trader by clicking on the pencil icon on the far right. This brings up the advanced setting per currency window. Under the ‘Type’ column, if I select ‘None’ for all CDF’s then I assume this will stop the positions from being opened?
I don’t want to choose traders who deal with CDF’s as it doesn’t match my money management strategy. I can choose a trader who historically has not done so but that doesn’t prevent this from happening going forward. I’m looking for a feature that will prevent the same from happening on my live account.
