Does anything beat buy & hold on Sandbox?
Every setup we tested on Sandbox — ranked out-of-sample, corrected for multiple testing, and forward-tracked in public from the day this page published. The honest answer is the headline.
No setup beat simply holding once tested honestly. We say so plainly.
Its best setup only beat buy-and-hold in one window — a regime artifact, not a strategy. Buy-and-hold benchmark: -4.4% CAGR over 8.9 years (-62.8% CAGR in the out-of-sample window).

Sandbox: Nothing Beat Buy-and-Hold, and We Checked Everything
For Sandbox, we ran 561 indicator configurations through the same pipeline we apply to every asset, and none cleared the bar. This is a common outcome in crypto, where simply holding SAND produced a buy-and-hold CAGR of -4.4%% — alongside a maximum drawdown of -85.8%%, which is the price of admission. When the baseline compounds that hard, a timing rule has to be genuinely predictive, not just lucky during one bull run, to add anything. In a market that trades around the clock and moves violently, most rules here simply stepped out of moves that holding captured for free.
The best-looking candidate was Order-Flow Reversion on the daily timeframe, posting an out-of-sample Sharpe of 0.77 against a multiple-testing hurdle of 2.17. That hurdle exists because picking the top result from 561 attempts manufactures apparent skill by construction. Only 98.5%% of setups beat holding at all, and the leader's edge did not hold up across 2.7 years of unseen data. Read this as evidence, not prophecy: crypto market structure shifts quickly, past performance does not predict future results, and a verdict of nothing today is a finding about history, not a forecast.
Every figure above is computed from our own backtests — nothing is estimated or invented. Hypothetical results; not investment advice.
The least-bad setups — shown with their failure numbers
Nothing here earned a verdict — these are the best of a losing field, published so you can see exactly how "best" still failed.
Order-Flow Reversion
What it is: An order-flow / liquidity model: it reads signed volume to judge whether buyers or sellers are actually being absorbed. Long/flat only — no leverage, no shorting. The parameters we tested are not published.
How it was tested: signals evaluated at daily-bar close, the position changes on the NEXT bar, 0.08% cost per side. Same engine, same cost model, same out-of-sample split as every other number on this site.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.77 · alpha +86.1% · 13 trades over 2.7 yrs.
Bollinger Mean-Reversion
What it is: A mean-reversion rule: it fades stretched moves and exits as price reverts toward its average. Long/flat only — no leverage, no shorting. The parameters we tested are not published.
How it was tested: signals evaluated at daily-bar close, the position changes on the NEXT bar, 0.08% cost per side. Same engine, same cost model, same out-of-sample split as every other number on this site.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.7 · alpha +84.2% · 15 trades over 2.7 yrs.
Fibonacci Bands
What it is: A channel / envelope rule: it measures how far price has travelled from a moving reference and acts at the extremes. Long/flat only — no leverage, no shorting. The parameters we tested are not published.
How it was tested: signals evaluated at daily-bar close, the position changes on the NEXT bar, 0.08% cost per side. Same engine, same cost model, same out-of-sample split as every other number on this site.
Out-of-sample (last ~30% of the window, never used to pick this setup): Sharpe 0.7 · alpha +84.2% · 15 trades over 2.7 yrs.
Since publication — including if it loses
The setup is ahead so far — over a window this short that is mostly noise. Marked to market nightly from real prices, rules frozen at publication, as of 2026-10-27. Currently FLAT.
We tested 561 setups (indicator × parameters × timeframe) on Sandbox. Only setups with ≥30 trades qualify (336 did). Setups are ranked by out-of-sample Sharpe — the last ~30% of history, which standard-parameter rules never saw during selection. Because picking the best of 561 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 2.17 (√(2 ln N)/√T) AND positive alpha in both windows. Of the eligible setups, 98.5% had positive out-of-sample alpha (median OOS Sharpe -0.82) — the table below is truncated, but this summary covers all of them. How we test: methodology. The scoring contract is published in full; the parameters of each individual setup are not.
