What's the difference between Straddle OC and regular Option Chain?

The Straddle Option Chain (Combined OC) combines Call and Put option data for each strike into a single row, while the regular Option Chain shows them separately. Straddle OC shows combined metrics (Volume, OI, LTP) for both calls and puts together, making it easier to quickly identify high-activity strikes or analyze total market interest at each strike level. Use Regular OC when you need to compare call vs put activity side-by-side or analyze individual option contracts.
