Scalping Explained: The Honest Math Behind It
Jan DreherJune 20266 min readScalping is trading by the minute: in, take a few points, out, many times a day. The idea feels reassuring, because small wins feel safer than big bets. The truth is in a calculation that almost no beginner runs before their first scalp: the fee math.
What scalping is
Scalpers trade on the smallest timeframes, usually 1- and 5-minute charts, and hold positions for seconds to minutes. The target per trade is small, often 0.2 to 0.5 percent, but there are many attempts a day. Scalping lives on repetition: the same setup, the same reaction, dozens of times.
The math that beats scalpers: fees
Every trade costs fees twice, on entry and on exit. With market orders you pay the taker fee, and at 0.055 percent that is 0.11 percent per round trip. If your target is 0.3 percent per scalp, you hand more than a third of your gross profit to the exchange, on every single trade.
In absolute numbers: 20 scalps a day at 500 USDT position size each cost 11 USDT in fees, every day. On a 1,000-USDT account that is 1.1 percent of account loss per day, from fees alone. The market first has to pay you back that 1.1 percent before you are even breakeven. That is why scalping is the strategy with the highest fee load, and the main reason it does not work for most people.
The most effective cost lever is maker orders: if you place limit orders into the book instead of taking with market orders, you pay the maker fee, at many exchanges 0.02 percent instead of 0.055. The same day then costs 4 instead of 11 USDT. The price for that is that limit orders are not always filled and you miss trades. Profitable scalpers optimize this dial first, long before they touch the setup.
What you need before scalping can work
- A fixed setup catalog: 1 to 2 patterns you have seen a hundred times, otherwise every impulse becomes a trade.
- Execution without hesitation: in scalping seconds decide, thinking mid-trade is too late.
- The fee math in your head: target and stop have to price in the 0.11 percent round-trip cost.
- Emotional neutrality after losses: 3 stops in 10 minutes are normal, revenge scalps ruin the day.
- Liquid markets: BTC and ETH, where the spread is tight. In illiquid coins the spread eats the scalp.
The scalper's opponent is not the market. It is the fee bill, and it wins on most days.
A realistic way into scalping
If you want to try it: take a single setup, for example the bounce off a clear support level on the 5-minute chart, with a fixed stop behind it and a target of at least 1.5 times the risk. Trade it 100 times in the simulator with play money and live prices, count the hit rate and honestly weigh the fees against it. After that you know whether scalping fits you, without the answer costing you money.
Frequently asked questions
How much can you make with scalping?
The honest answer: most people lose money with it, because fees and spread bite harder at high trade frequency than with any other strategy. Those who scalp profitably have a rehearsed setup, iron discipline, and count in net numbers after fees. Concrete earnings promises for scalping are a reliable sign of dishonest sources.
Which timeframe is best for scalping?
The 1- and 5-minute charts are standard, with the 15-minute chart as context for levels. For getting started, the 5-minute chart is the better start: it leaves a few more seconds for decisions and filters out some of the noise that dominates the 1-minute chart.
Which markets are suited to scalping?
Only highly liquid markets with a tight spread, which in crypto means mainly BTC and ETH perpetuals. On small altcoins the spread is often wider than a scalp's profit target, so you lose on entry already. The trading hour matters too: during high-activity phases spreads are tighter and moves are cleaner.
Is scalping suitable for beginners?
It is the most demanding strategy to start with, because it requires speed, discipline, and fee awareness all at once. The reverse path is smarter: first solidify the basics and risk management on calmer timeframes, then test scalping in the simulator with 100 practice trades. Anyone who scalps straight away with real money pays tuition by the minute.
