It gets addicting fast, you basically bet on if a stock will rise or fall. You purchase a call(rise) or put(fall) and the in order for best profits sell 30 minutes after market opens. Try to find a stock broker app in your country, use stuff like robinhood which is no commission for small funds around 1K-10K, but if you want to go above that you need to look for a trading app that has more extensive tools. I highly recommend people to look into it as there can be some serious money to be made.
