Which chart a condition reads depends on the instrument and expiry you pick in Instrument Name.
- Spot (index): select the index under NFO and leave the expiry blank.
- Futures: select the index and add an expiry month (e.g. current month).
- Option: select the option contract (strike and expiry) as the instrument.
For strike selection in the Position builder:
- The plain ATM keyword picks strikes from the futures price.
- ATM SPOT picks strikes from the spot price.
MCX and crypto have only a futures chart, so the spot/futures choice applies to NFO/BFO indices.
