Alpha Foundry · Separately governed research
Put the strategy’s numbers through review.
Keep gains, losses, costs and open positions visible. Inspect the supplied evidence before deciding which research deserves the next proving step.
Research and calculation only. A ledger upload does not authenticate its source, promote a strategy, establish customer eligibility or authorize capital movement.

Use a JSON ledger with closed and open positions, all costs, and chronological account-equity observations. The calculation stays in this browser. It reports the supplied numbers and their limits; it does not grant a strategy an Evidence Level.
Required inputs and calculation boundaries
- Use one currency and amounts with at most two decimal places. Costs must be zero or positive. Include fees, slippage and other costs separately.
- An open position has null closed_at and gross_pnl. Its costs are reported separately; its unrealized value belongs in total-account equity.
- Supply first and last equity observations for the complete window. Nonzero external deposits or withdrawals are refused, because this review does not adjust cash flows.
- Holdout trades must open after training ended, with a declared strategy freeze and holdout reference. Chronology alone does not independently validate OOS performance.
- Capacity, capital cap, kill rules and failure modes are preserved as supplied declarations. No promotion or capital authority is created.
Supplied input — source and origin are unverified. Editing the input clears the previous result.
