(2/n) Crown can be made only if the IronFly is in profit. If we have Rs 500 profit outside the buy strikes then we can convert that IronFly to crown.

(3/n) Keep shifting buy strike towards sell strike after every Rs 500 profit per lot.

(4/n) By doing this IronFly won't have loss outside buy strike. Minimum profit required outside buy leg is Rs 500 on 1 lot to convert it to crown.

(5/n) After this all you need to do is add butterfly starting from the buy strikes. How many butterfly you add or which side you add depend on your view for Nifty.

(6/n) Apart from this, there are adjustments that we can do to increase profit on low profit zones. We will try to explain them also some other time.

(7/7) Those who still don't believe or worried about brokerages and taxes can simply ignore this.
