Terms like "market order", "limit order", "trailing stop loss", and "bracket order" may sound complicated but in reality, they are simple concepts that you can understand with just a little bit of work. It's best to think of them as tools in your stock trading arsenal. For instance, if you want to put in an order that will keep following a stock price as it rises so you don't lose any upside, but sells your stake if the market starts to crash, you can do that. If you want to buy shares and put in an order at a predetermined amount below a specific price so you limit your losses, you can do that, too.
