Option close prices of 5 min candles in multiple of 500 strikes

Suppose Banknifty spot price is 51311, I wants close prices of 5 minute candles of strike multipes 500. i.e. of 51000 CE , 50500 CE,…

try with round keyword.

Get the strikes with Round to base 500, then step by 500.

Strikes

• Nearest 500 strike: Round(LTP(NIFTY BANK), '500'). Round goes to the nearest multiple, so 51311 gives 51500.
• The 500 strike at or below spot: Round(Math Operation(LTP(NIFTY BANK), Number(250), '-'), '500') → 51061 rounds to 51000.
• Further strikes: subtract 500, 1000 and so on with Math Operation.

5-minute close of each option

For each strike, build the option instrument (NIFTY BANK, expiry, that strike, CE) and read the last closed candle:
Position(CLOSE(Symbol(<that option>, '5m')), -1)

Check on the live option chain that each strike exists for your expiry. Test in Live Offline and see the values in the Notification Log. Keyword reference: Keyword Documentation — Tradetron
