The CFTC glossary describes a scalper as a trader "who buys and sells rapidly, with small profits or losses, holding his positions for only a short time during a trading session." This simulator gives you that job on real data. Each round is a real stretch of 1-minute candles from bitcoin, ether, solana, XRP or dogecoin on a day drawn at random from 2023 to 2026: 30 minutes of history from 13:00 UTC, then two hours to trade.
When the two hours end, the simulator closes any open trade, reveals the market and the date, and lists every trade before and after costs next to the result of simply holding.
With a 0.1% fee on each side and 0.05% slippage on each market order, a trade has to move about 0.30% in your favor just to break even. That is a lot for one minute. In the 200 real two-hour windows behind this game, 24,000 minutes in all, the median 1-minute candle spanned 0.12% from high to low, and only 12.5% of minutes had a range of 0.30% or more. The median price change over five minutes was 0.13%.
| Market | Median 1-minute range | Median 5-minute move | 5-minute moves above the cost |
|---|---|---|---|
| Bitcoin | 0.073% | 0.082% | 10.5% |
| Ether | 0.115% | 0.119% | 17.6% |
| Solana | 0.143% | 0.162% | 26.7% |
| XRP | 0.135% | 0.150% | 25.2% |
| Dogecoin | 0.139% | 0.158% | 27.1% |
Imagine knowing the direction of the next five minutes every time and trading $10,000 at each minute's open. Across 23,000 such five-minute trades, only 21.5% made money after costs, and the average trade lost $9.03. With one-minute holds, perfect calls made money 4.7% of the time and lost $20.71 on average. Buying at every open and selling five minutes later lost $29.59 per trade.
So at these costs the size of a move matters as much as its direction. FINRA's investor page on frequent intraday trading notes that such traders "might attempt to profit from small price movements," and adds: "Attempting to capture profits in the short term is generally less reliable than investing long-term." The simulator lets you feel why before any real money is involved.
The result table puts your trades next to three benchmarks. The row before fees and slippage shows what the same entries and exits would have made at the raw prices. The average price move per trade sits next to the 0.30% that one round trip costs. Minutes in a trade shows how much of the two hours your money was at work, and the last row shows what one long trade held for the whole two hours would have made with the same costs. If most of your trades won before costs but the round lost after them, the costs, not your reads, decided the result.
Educational, not financial advice. The simulator replays real past prices with play money. It does not recommend scalping or any other trading.
A practice game for very short trades. You watch a real 1-minute chart move in real time, open and close trades within minutes with play money, and see the result after fees and slippage.
Yes. Every candle is a real Bybit spot 1-minute candle, downloaded with the ccxt library, from 200 windows of 13:00 to 15:30 UTC on days from 2023 to 2026. Prices are shown as an index that starts at 100; the market and the date appear when the round ends.
Costs. A round trip in this game costs about 0.30% of the trade value: a 0.1% fee on each fill plus 0.05% slippage on each market order. A trade that moved 0.2% your way still loses money after costs.
In the real windows behind the game, bitcoin moved least per minute: its five-minute moves beat the cost 10.5% of the time, against 26.7% for solana. Bigger moves also mean bigger losses when you are wrong.
The day trading simulator moves a simulated ticker. This one replays real Bybit 1-minute candles, charges a fee on every fill and shows your trades before and after costs.
