FundingKilled

Does yesterday’s funding predict tomorrow’s Bitcoin move?

No link

yesterday’s funding tells you nothing about tomorrow’s move, and any edge is below costs

In plain English

Yesterday’s funding rate tells you nothing useful about tomorrow’s price direction, and even if it did, the edge is too small to cover costs.

What was claimed

Yesterday's funding rate tells you which way Bitcoin moves tomorrow.

The bar it had to clear

a real day-to-day link, and an edge above the ~6 bps cost

What the data said

no real link, and any edge (~4.8 bps) is below costs

Why it's dead

Funding rates on BTC have no usable lag-1 autocorrelation (no reliable link between one day's reading and the next). The spread also fails to clear the cost floor even if the direction were right.

The detail

BTC autocorrelation: r=−0.0599 (r measures that day-to-day link on a −1 to +1 scale; this is essentially zero, and negative), fails the r≥0.05 threshold, and the sign is wrong. SOL r≈0, p≈0.99. Estimated edge at the strongest in-sample cell (the best-looking slice of the very data it was fitted on) ~4.8 bps vs 6.0 bps round-trip cost, sub-cost at full conviction.

Kill date: 2026-04-28
Sample: BTC + SOL funding history
Method: Documented kill
Verdict: no autocorrelation + sub-cost

What it would have done to your money

You put in$10,000

You run it for200 trades

You would have

You started with$10,000

This strategy left you$8,869

Instead of not trading$10,000

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.
