What is Bull put spread strategy?

Bull Put Spread

Bull put spreads can be executed by selling a higher strike price in-the-money put option and buying a lower strike price out-of-the-money put option. Both the puts have the same underlying stock and the same expiration date as shown in the graph below.

We buy out-the-money long put which is 15000 and the premium paid is 199.25. We have to sell an in-the-money short put which is 15100 and the premium received is 233.3.
