RSI Mean Reversion Backtest in Crypto: Fees, Slippage and Break-Even Costs

RSI mean-reversion rules buy oversold dips and sell into recovery. They trade often, hold briefly and earn small amounts per trade, which makes costs decisive.

Short answer

An RSI mean-reversion strategy (for example, buy when RSI(2) or RSI(14) drops below a threshold, exit on recovery) typically produces many short trades with small average gains. Its break-even cost is its gross average return per trade: if that is +0.12% and round-trip fees plus slippage are 0.14%, it loses money. Entries happen during sell-offs when spreads widen, so slippage is higher than average. Test with next-bar fills, maker vs taker fees and a trend filter that avoids buying dips in strong downtrends.

Strategy-specific pitfalls

  • Falling knives: oversold can stay oversold in crashes; a trend filter (e.g. price above a long moving average) cuts the worst losses.
  • Entry slippage in sell-offs: model higher slippage when bar range is large.
  • Exit on RSI recovery: exits on closed bars only; intrabar RSI changes (see RSI in Crypto: Why the Value Changes Before Candle Close).

Questions readers ask

Why do RSI mean-reversion backtests fail live?

Small per-trade edges and higher real slippage during sell-offs.

What is break-even cost?

The gross average return per trade.

Does a trend filter help?

It often reduces falling-knife losses; test it out of sample.
