Put the condition below in the Strike Fx of the Position Builder to select the ATM strike from the index spot price using the Get Strike keyword:
Simpler option: ATM SPOT
You can also use the ATM SPOT keyword directly in Strike Fx:
- ATM SPOT uses the index spot chart and works for any expiry.
- ATM uses the monthly futures chart, so it can differ from the spot-based ATM.
- On MCX, there is no spot chart. Use ATM, not ATM SPOT.
