Options Trading

Can margin be changed during the life of contract?

Yes, margin % can be changed during the life of the contract depending on the volatility in the market. It may so happen that you have taken your position and 25% margin is taken for the same. But later on due to the increased volatility in the prices, the margin % is increased to 30%. In that scenario, you will have to allocate additional funds to continue with open position. Please note - Exchange has identified option contracts in either Deep Out of The Money (OTM) or Non Deep OTM for which Exchange has stipulated separate Exposure percentage (also known as Extreme loss margin percentage). Hence accordingly for Deep OTM or Non Deep OTM option contracts Initial Margin percentage and Minimum Margin percentage would be revised accordingly.
