I run the Z12 system on a 3200 USD account with margin 30 and risk 10.
It has never opened any indicies. In log it says

NAS100 Skipped Margin 14 min 49
GER30 Skipped Margin 8 min 113

Broker has minimum 1 lot and 1 lot steps for indicies

Is there any way to allow these trades, but not over expose currency pairs. Account has 1:888 leverage on forex, but 1:100 on indicies
