The hedged margin is the funds which are required to open and support an open locked (hedged) position. They are open positions on the same instrument in different directions.
The calculation of the margin hedge has several steps:
For uncovered volume
For covered volume (if the hedged margin size is specified)
The resulting margin value is calculated as the sum of the margins calculated at each step.
The size of the hedged margin for locked positions can be found on our site and our trading platform in the contract specifications for each instrument.
