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.
If a position is held overnight, it may only be closed in two parts maximum. This rule applies to all positions on the same pair and in the same direction that are opened within 15 minutes of each other.
If a position is closed in more than two parts across different trading days, its profits will not be eligible for payout.
