A trader in my DMs just told me his $ETH buy filled almost 3% above where he clicked. Here is what it actually means, and it is not bad luck, it is that he had no idea what order type he was even using.
This is the part nobody explains before you start trading. You open Binance, you type a number, you hit buy, and you assume the number you typed is the number you get. It is not, and the order type you pick decides that difference every single time. Most traders blow themselves up on slippage and fees before they even understand what leverage does, because they never learned this first.
Let me actually break down the three you will use every single day.
Market order is the simplest and the most dangerous if you do not respect it. You are telling the exchange, fill me right now, whatever the price is. Say $ETH is sitting around 3,200 and the order book is a little thin because it is 3am and volume is low. You slam a market buy and instead of 3,200 you get filled at 3,230. That is a 1% loss before the trade even started moving, and you paid it just for being in a hurry. Market orders are for when speed actually matters more than price, like getting out of a position fast when things are breaking down.
Limit order flips the whole thing around. You are telling the exchange, I only want this price or better, and I am willing to wait. Say ETH is at 3,200 and you actually want to buy the dip, you set a limit at 3,180 and walk away. If price comes down to 3,180 you get filled exactly there, no slippage, no surprise. If it never comes, you simply do not get filled, and that is fine too, because a trade you did not take is better than a trade you overpaid for. This is the order type for planned entries, the ones you have levels for and patience for.
Stop order is the one that protects you when you are not even watching the screen. You set a trigger price, and once the market touches it, the order activates. Say you bought ETH at 3,200 and you do not want to lose more than 3%, you set your stop around 3,100. If price drops to 3,100 your stop triggers and closes you out. The thing most people do not realize is a basic stop usually becomes a market order the second it triggers, so in a fast crash it can still fill a bit lower than your exact number. That is not the stop failing, that is just how a sudden move works, and it is still infinitely better than sitting there hoping while ETH keeps falling.
Here is the actual rule I use and it is not complicated. Market orders are for when you need out now and price is secondary. Limit orders are for entries you have actually planned, where you know your level and you can wait for it. Stop orders are for protecting a position after you are already in, especially when you cannot sit and watch every candle.
The traders who keep bleeding on fills are the ones using market orders for everything because it feels faster and easier. It is faster. It is also how you donate 1% here and 1% there until it adds up to a real number over a month of trading ETH.
So before your next trade, actually check which order type is selected before you click confirm. If you are entering, use a limit and give it a real level. If you are protecting a position, set your stop before you close the app, not after price already moved against you. This one habit alone will clean up more of your losses than any indicator ever will.
