$Tiger Brokers(TIGR)$ To be honest ,if you're a beginner in options trading ,I will suggest that you only sell put and sell call for premium..

 When you sell a put below the stock price ,you can acquire the shares at a lower price which is below your strike price yet you're paid with premium with or without hitting the strike price .Example stock price 10 , you sell a put at 9.5 strike ,you will not be assigned if the stock price is above 9.5.

when you sell a call that will be , shares would be assigned out if it goes above your strike price and premium is also paid with or without hitting strike price .Example stock price 10 , you sell a call at 10.5 ,your shares will not be assigned out if it is less than 10.5

In other words , selling put or selling call gives you an extra edge even the stock price didnt move much but you will be able to generate consistent premium by selling them . That's the edge for selling put and call options ..Good luck to all! Stay safe .
