Knowing different order types is key for smart trading. A market order executes instantly at the current price, best for quick entries/exits. A limit order lets you set the price you want; it only executes if the market hits that level. A stop-loss order protects you from huge losses by triggering a sell if price drops below a certain point. Advanced traders may use OCO (One Cancels the Other) to combine limit and stop orders. Using the right order type can help you avoid FOMO, reduce risk, and stay in control. Never trade blindly!
