Does anything beat buy & hold on EUR/CAD?
Every setup we tested on EUR/CAD — 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's out-of-sample profit factor (0.6) is below 1 — it lost money per trade on unseen data. Buy-and-hold benchmark: +0.1% CAGR over 23.2 years (+1.4% CAGR in the out-of-sample window).

EUR/CAD: 693 Indicators Tested, None Earned Their Keep
Currency pairs like EUR/CAD should be fertile ground for indicators. There's almost no long-run drift to compete against — EURCAD's buy-and-hold CAGR of +0.1%% is a low bar — and mean reversion is the textbook behavior of macro-anchored exchange rates. Yet across 693 tested setups, none cleared that bar honestly. The patterns that looked tradeable in-sample fell apart on data they hadn't seen. When an asset barely trends and timing signals still can't add value, the plainest explanation is that the apparent edges were noise dressed up as structure.
The best performer here, Fisher Transform on the daily timeframe, posted an out-of-sample Sharpe of 1.34 against a required hurdle of 1.37 — a hurdle that exists because picking the winner from 693 attempts is data-mining by construction. Its out-of-sample alpha of +5.2%% across 570 trades over 7.0 years tells you what the in-sample fit concealed. Only 3.3%% of setups beat holding at all, before any statistical correction. Read this as a snapshot, not a verdict on the future: regimes shift, and past results describe what happened, not what will.
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.
Fisher Transform
What it is: An oscillator rule: it reads a bounded momentum gauge and takes exposure when it turns from an extreme. 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 1.34 · alpha +5.2% · 166 trades over 7.0 yrs.
Parabolic SAR (fast)
What it is: A trend-following rule: it holds while a smoothed trend reference is pointing up and goes flat when it turns. 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 0.89 · alpha +2.9% · 138 trades over 7.0 yrs.
DeMarker (7)
What it is: A momentum rule: it holds while rate-of-change stays positive and steps aside when it rolls over. 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 0.8 · alpha +2.5% · 131 trades over 7.0 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 2026-09-11. Currently LONG.
We tested 693 setups (indicator × parameters × timeframe) on EUR/CAD. Only setups with ≥30 trades qualify (577 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 693 tries mines even the holdout, the VALIDATED verdict additionally requires the top setup’s OOS Sharpe to clear a selection hurdle of 1.37 (√(2 ln N)/√T) AND positive alpha in both windows. Of the eligible setups, 3.3% had positive out-of-sample alpha (median OOS Sharpe -0.3) — 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.
