I am implementing a Long Iron Condor strategy on Bank Nifty Options (Intraday) with the following strike positions on the expiry day, when the current market price is ₹51,365.70 (rounded to ₹51,400). The legs of the strategy are:

51500 CE Buy at ₹32

51700 CE Sell at ₹14.3

51100 PE Buy at ₹15.05

50900 PE Sell at ₹7.35

The required margin for this strategy is ₹31,522.

I would appreciate your assistance in understanding a few aspects:

**SPAN and EXPOSURE Margin Calculation**: How do I calculate the SPAN and EXPOSURE Margin while selling options? If there are predefined percentages or formulas available for these calculations, it would be helpful for me to understand them.

**Margin Impact with Market Movement**: If I enter the above positions at the market open (9:15 AM) and the market moves up or down by 1,000 points during the day, how would this impact the required margin for this strategy?
