Market order is for those who are in a hurry but pay dearly; you enter at the price the market gives you, and if there is low liquidity or high volume, you may end up entering much worse than you expected. Limit order is for those who have patience; you choose the price and wait for the market to come to you. It is the most strategic way to enter or exit without surprises. Stop loss is the shield of the disciplined trader; you set the limit of loss there and that’s it. If the market goes against you, you exit before it turns into a tragedy. Take profit is the button of wisdom; knowing where to exit with a profit is just as important as knowing where to enter. Many lose while winning because they don't know when to stop. There are also OCO, trailing stop, and other tools that seem advanced, but they are just upgrades of the basics.
