Fear & Greed Timing: does it work?
Beyond the plain buy-fear, sell-greed rule, traders use the crypto Fear & Greed Index as a timing layer: only run momentum when sentiment is greedy, or add an override after extreme fear.
The rule we tested. Three ways to use the index as a timing input, each compared against buy-and-hold of the same coins: momentum switched on or off by the reading, a four-week momentum rule with an extreme-fear override, and simply holding while the reading is neutral or above. The contrarian version is included for reference.
- Two-week momentum only in greed, BTC in fear (18 crypto pairs (BTCUSDT, BNBUSDT, XRPUSDT, ADAUSDT, …)), 2017-08-18 to 2025-03-14, costs 0.10%–0.17% per side: +39.5 pts/yr vs buy-and-hold across 186 trades, p=0.050, q=1.000 after correction: beat buy-and-hold and was significant before correction.
- Crypto 4-week momentum plus a 90-day extreme-fear override (18 crypto pairs (BTCUSDT, BNBUSDT, XRPUSDT, ADAUSDT, …)), 2017-08-18 to 2025-03-14, costs 0.10%–0.17% per side: +40.6 pts/yr vs buy-and-hold across 1,197 trades, p=0.068, q=1.000 after correction: beat buy-and-hold on the raw number, but not significantly.
- Crypto held while Fear & Greed is 50 or above (18 crypto pairs (BTCUSDT, BNBUSDT, XRPUSDT, ADAUSDT, …)), 2017-08-18 to 2025-03-14, costs 0.10%–0.17% per side: +0.6 pts/yr vs buy-and-hold across 1,335 trades, p=0.483, q=1.000 after correction: beat buy-and-hold on the raw number, but not significantly.
- Crypto Fear & Greed Index contrarian entries (1 crypto pair (BTCUSDT)), 2017-08-18 to 2025-03-14, costs 0.10% per side: −59.6 pts/yr vs buy-and-hold across 72 trades, p=1.000, q=1.000 after correction: did not beat buy-and-hold.
Some versions finished ahead of buy-and-hold before correction: crypto pairs +39.5 pts/yr vs buy-and-hold (p=0.050, q=1.000); crypto pairs +40.6 pts/yr vs buy-and-hold (p=0.068, q=1.000); crypto pairs +0.6 pts/yr vs buy-and-hold (p=0.483, q=1.000); crypto pair −59.6 pts/yr vs buy-and-hold (p=1.000, q=1.000). None cleared Tickfloor's Benjamini-Hochberg q<0.10 bar once weighed against every other rule tested alongside it.
Stress tests on the discovery data
Same data, harder conditions. Excess is CAGR minus buy-and-hold CAGR.
- Two-week momentum only in greed, BTC in fear: +39.5 pts/yr vs buy-and-hold as tested; +32.1 pts/yr with costs doubled; NaN pts/yr with BTC, its biggest contributor, removed; +43.0 pts/yr and +52.2 pts/yr with the main lookback moved down and up by a quarter.
- Crypto 4-week momentum plus a 90-day extreme-fear override: +40.6 pts/yr vs buy-and-hold as tested; +35.6 pts/yr with costs doubled; +35.1 pts/yr with ADA, its biggest contributor, removed; +13.7 pts/yr and +37.8 pts/yr with the main lookback moved down and up by a quarter.
This is one line in a wider check: Tickfloor's research desk has run 517 strategies against buy-and-hold, and after correcting for how many were tested (Benjamini-Hochberg, 598 tests), 0 survived. A single win-rate claim like this one is exactly the kind of result that check exists to catch before anyone trades on it.

Does Fear & Greed timing work?
Some versions finished ahead of buy-and-hold before correction: crypto pairs +39.5 pts/yr vs buy-and-hold (p=0.050, q=1.000); crypto pairs +40.6 pts/yr vs buy-and-hold (p=0.068, q=1.000); crypto pairs +0.6 pts/yr vs buy-and-hold (p=0.483, q=1.000); crypto pair −59.6 pts/yr vs buy-and-hold (p=1.000, q=1.000). None cleared Tickfloor's Benjamini-Hochberg q<0.10 bar once weighed against every other rule tested alongside it.
What exact rule did Tickfloor test?
Three ways to use the index as a timing input, each compared against buy-and-hold of the same coins: momentum switched on or off by the reading, a four-week momentum rule with an extreme-fear override, and simply holding while the reading is neutral or above. The contrarian version is included for reference.
Is this the same as the Fear & Greed contrarian page?
No. The contrarian rule (buy extreme fear, sell extreme greed) has its own page, linked below. This one covers using the index as a filter or timing layer on other rules.
Did it hold up in stress tests and on later data?
Two-week momentum only in greed, BTC in fear showed +32.1 pts/yr with costs doubled; Crypto 4-week momentum plus a 90-day extreme-fear override showed +35.6 pts/yr with costs doubled. None of this is an edge: Tickfloor's correction for multiple testing left 0 survivors out of 598 tests.
Is this financial advice?
