How this is calculated
A static limit is measured once from the starting balance and never moves. An intraday trailing limit follows your highest equity tick by tick, including unrealised profit. An end-of-day trailing limit only moves once the session closes. The buffer is the distance between your current equity and the level that closes the account — that is the number to size against.
