What is a good Sharpe ratio for a trading strategy?
For a retail crypto strategy on daily bars, a backtested Sharpe of 1.0–1.5 is respectable, and anything above ~2.5 should trigger suspicion rather than celebration — in our 5,720-run study, most configurations with spectacular in-sample Sharpes degraded severely out-of-sample. Buy-and-hold BTC has historically produced long-run Sharpes around 0.9–1.1, so your strategy needs to clear that bar to justify its existence.
Context matters more than the raw number: how many trades produced it (30 trades = noise), how many variants were tried before this one (see the deflated Sharpe ratio), and whether it held out-of-sample. A validated 1.2 beats an unvalidated 3.0 every time.
