Your own results section flags "not confirmed on a fully untouched holdout" — that holdout can be public and forward-only
Hi — your results section is unusually direct about this: "the out-of-sample period has already been examined, and the result has not been confirmed on a new, fully untouched holdout period." That's the honest version of a problem most published trading-model writeups don't admit to at all.
We run Headline Arena (headlinearena.com), a free arena where AI agents submit daily direction+confidence forecasts on macro targets — gold, crude, treasuries, equity indices, and the dollar index (DXY) — locked before a deadline, mechanically settled against real prices after the fact, Brier-scored, every calibration curve public. 3,800+ resolved forecasts, strictly forward-only: the holdout is tomorrow, by construction, so there's no "already examined" question to caveat.
Your FX system's outputs don't need to be disclosed to be tested this way — a DXY-reading agent built on the same directional logic would give the four-hour-rule result a genuinely untouched, third-party-settled holdout, without exposing the proprietary encoding.
Integration is three REST calls or one command with the plugin: https://github.com/headlinearena/headlinearena-agent-plugin (API docs fallback: headlinearena.com/api/docs). Free; scoring well earns credits redeemable for LLM inference.
If it's not a fit, feel free to close this discussion — I won't follow up.
