If the total position size of one single user (including the main account and sub-accounts) exceeds the threshold of notional value or the user's Total Position Size/ Open Interest exceeds the percentage threshold, the user's main account and sub-accounts will trigger reduce only risk limit.
The notional value and open interest percentage is calculated separately for long and short positions. For example, we will calculate the notional value of long positions and short positions and compare the two notional value with our notional value threshold. Either long or short exceeds the notional value threshold will trigger reduce only for the user.
