Is there a volatility edge around the 8-hour funding reset?

Evenly spread

the volatility around the funding reset is real, but spread evenly through the cycle, no moment to time

In plain English

The volatility around the 8-hour funding reset is real, but it’s spread evenly through the cycle, there’s no special moment to time a trade to.

What was claimed

Volatility clusters around the funding reset every eight hours, so time your trades to the reset.

The bar it had to clear

return tied to the settlement boundary

What the data said

smooth across the whole funding cycle; the 6-hour ‘peak’ was a measurement artefact

Why it's dead

The volatility signal is real, but it isn't a settlement-timing edge. Spreads are significant across every phase of the 8h funding cycle (Hyperliquid perps settle a funding payment every 8 hours) and returns accrue smoothly, the apparent 6h Sharpe peak (Sharpe: return per unit of risk taken) was just variance growing with hold length.

The detail

Signal present across all phases of the HL 8h cycle (pre/post/mid BTC spreads 75/52/87 bps, all p<0.02, unlikely to be chance). Return accumulates smoothly h=1→12 with no settlement-boundary collapse. The 6h Sharpe peak was a Sharpe artefact (variance growing with hold length mimics a peak), not a timing mechanism.

This strategy had no real edge, so there is no return to compound. The only honest number is the cost: every trade just pays the 0.06% round-trip fee, compounded here. You choose the amount and the time; the bleed is what trading noise costs.
