Robinhood trading stocks

I am new to the stock market investment and tried buying few stocks on Robinhood app. I want to understand the trading aspect (Selling stock). I can see lot of options like market order, limit order, stop order, stop limit order. Which one is usually preferred and why. Also I have read that Robinhood average out the stock price while sellling. What's about that.

If you didn't get it, you shouldn't be using those. Not being rude, it's for your own good.

This. Also IMO most people should stop speculating on Robinhood entirely.
