Search for the underlying, such as SENSEX, from your Watchlist, then pick the exact contract tagged BSE FO from the results and tap + to add it — the same way you'd add any Futures & Options (F&O) contract on Rupeezy.
How to add a BSE F&O contract to your Watchlist

1. Tap the + icon next to "My Watchlist", or the search icon at the top of the Watchlist screen.
2. Type the underlying's name — for example, SENSEX. The results list shows the cash-market index/stock first, tagged BSE, followed by every futures and options contract on it, each tagged BSE FO. Futures show just their expiry date; options also show the strike and CE/PE. Use the Option or Future filter tab above the results to narrow a long list down to just one type.
3. Tap the + next to the exact contract you want. It turns into a checkmark, and a bar appears at the bottom showing how many you've selected. You can tap + on more than one contract before adding them together.
4. Tap Done on that bar. You're taken back to your Watchlist, an "Added to watchlist" confirmation appears, and the contract shows up in your list tagged BSE_FO with its expiry (and strike/type, for options).
Things to keep in mind
- The + only adds the contract to your Watchlist for tracking. It doesn't place an order. Tap the contract itself (not the +) to open its detail screen and trade it.
- Each expiry and strike is a separate contract with its own row in search, so make sure you're adding the one you actually meant to track.
- Want to see every strike for an expiry at once before picking one? Use the Futures Chain or Option Chain instead.
