By rolling the 415/420 Bear Call Spread to the 16 Jun 23 expiration date, we were able to get a net credit of $0.36. With this credit, we were able to increase our max profit by $36 and reduce our max loss by $36. So if we had initially sold the Bear Call Spread for $1.50, that would mean our initial max profit was $150 and our max loss was $350.
