#OrderTypes101 How market orders, limit orders, stop-loss, and take-profit work. This is a very important step: choosing the type of order to trade. I prefer the limit order, that is, I buy at the price I choose and sell as well... with the market order, that is, at the market price, the purchase price often makes some movement and you lose a little on this... because buying at a good price is 80% of success.
