Understanding the types of orders is fundamental to trading intelligently. The most common are: market order, which is executed at the current price; limit order, which is executed only if a specific price is reached; and stop-limit, which is triggered when a certain trigger price is reached. For example, if you buy BTC at $65,000 and want to protect yourself from a drop, you can set a stop-limit to sell if it drops to $63,000. This helps you limit losses without having to watch the market all day.
