To create a custom strategy, navigate to the Strategy Builder section by hovering on Trade in the navigation bar on the home screen and then select Strategy Builder.

Now click on the ‘Create Strategy’ button, as indicated in the screenshot below.

On the Create Strategy page, search for the stock or index and your preferred expiry. By default, it's Nifty 50, with its most recent expiry selected.

Now click the ‘Open Option Chain’ button on the right. The Buy or Sell button will appear. Click either button to select a strategy.

If you choose to Buy a 22,700 Call, you select it, and SmartOptions populates it in the Strategy legs section in the left pane. You can analyse your strategy from here and then click on ‘Trade All’ to trade it.

You can save this strategy for future reference by clicking the Save Strategy button.
