Fees

FEES DECIDE

In short

18% of our fast, 15-minute strategies made money. Then we added fees. 4%.

The faster you trade, the more fees you pay per unit of risk. On daily candles, 59% of versions survived fees. On 15-minute candles, 4%.

Before you look for an edge, count what each trade costs.

How we measured it

Every number comes from the lab's database: 19905 strategy versions with at least 100 trades each, tested on crypto perpetual futures from 2022 to 2025 with fees, slippage and funding. One version = one strategy with one set of settings. Results are in R (the amount risked per trade).

What to do instead

Verify it yourself

  1. Write the rule exactly (below: our specification and every setting we tried).
  2. Get free data: Binance's public archive (data.binance.vision) has years of candles; OKX and most exchanges offer an API.
  3. Include costs: fees on both sides, slippage, and funding for perpetual futures.
  4. Count results in R (risk per trade), not in %, and look at the typical version, not the best one.
  5. Split your data in two and keep a part you never look at until the end.
  6. Compare with simply holding the market over the same days.
