Options are the second level of trading when you get into the stock market. You can simple sell call options on your owned stocks (some brokers allow you to sell options without having the stocks in hand thought, that way the risk is so high that you don't want to take the risk as a naive person). The selling of call option is like renting a home and hoping its value goes up (or in some case goes down and you make money on your rent.). I have found a bunch of tutuorials online, videos, texts and much much more but I liked the one below a lot. After seeing this one I put my first call option sell order and hope to cash some money.
The first one covers the basic of call option while the second one helps you to handle more sophisticated ways of dealing with options and getting to know it better.
