Yes, partial closes are allowed.
Note: Partial closes must not be used solely to influence the consistency score.
If a trader holds a position overnight, once any part of it is closed, the remaining portion must be fully closed within that same trading day.
Violating this rule will cause the profits from the trade to be ineligible for performance reward.
Note: Positions opened within 15 minutes of each other on the same instrument will be considered as one single position when enforcing the Partial closing rule.
