Rules first, then evidence.

What we trade

The portfolio holds a set of strategy sleeves in liquid, US-listed exchange-traded funds. Five rules-based strategies each receive a fixed share of a portfolio risk budget. The budget is expressed as value at risk (VaR): the loss that a 30-trading-day holding period would be expected to exceed only 5% of the time, estimated by historical simulation over a rolling five-year window. Positions are re-sized to that budget before every session, so the budget is applied daily but measures risk over a 30-day horizon, not a single day. Conviction does not change position size.

How a trading day runs

1. Refresh Overnight, prices and holdings data are refreshed from the data vendors.
2. Decide Each strategy computes its target for the next session from the rules alone.
3. Check Pre-trade checks cover leverage, buying power and margin. A failed check stops the session.
4. Send Orders go to the broker as market-on-open orders.
5. Reconcile Fills are reconciled against the broker's own records the same day.
6. Record A daily record of positions, orders and fills is written and kept.

Trading runs only from versioned, reviewed software releases with a recorded rollback. A change reaches trading only after review, a release, and a first live session observed end to end.

Risk discipline

• One budget, fixed shares. Risk is allocated to sleeves by rule, so no sleeve can grow because it has recently done well.
• Checks before orders. Leverage, buying power and margin are verified before anything is sent. The system prefers not trading to trading on a failed check.
• Reconcile daily. Book and broker are compared every session, so a mismatch is seen within a day rather than at month end.
• Defects are recorded. When a check fails to catch something, the record says what broke, what it affected, and what changed.

How we label results

No performance figures are published on this site at present. When results appear, they carry one of three labels wherever a figure is shown, and the labels are never mixed in a single number.

• BACKTESTResearch simulations on historical data. In-sample unless stated otherwise. A backtest shows what a rule would have done, not what an account did.
• PAPERA simulated brokerage account with real fills at real prices and no capital at risk. Paper results do not reflect the market impact of real capital or the full cost of trading.
• LIVEReal money. There is no live track. Quantcore Labs does not manage client assets.

Any published figure will carry a data cutoff, and corrections will be made in place with a visible revision note rather than silently rewritten.

What this is not

A system under construction with a short public record. Nothing here is investment advice, an offer, or a solicitation. Quantcore Labs does not manage client assets.
