Selected work

Evidence, assumptions, and limits — shown together.

These examples demonstrate how we move from strategy design to out-of-sample evidence and risk interpretation. They are research studies, not live track records.

Case 01 · NQ CALL / PUT

CALL–PUT walk-forward research

How stable are strategy candidates when market chronology is preserved and results are judged outside the training window?

250valid candidates
125 / 125CALL / PUT candidates
10,000paths per candidate
US$100,000initial simulated capital
METHOD

Rolling studies separate parameter discovery from monthly out-of-sample evaluation. Selected candidates are replayed, compared by side, and subjected to Monte Carlo stress analysis.

EVIDENCE

The paired NQ overviews show the CALL and PUT candidate pools. Candidate ranks combine loss probability, drawdown-tail estimates, downside terminal value, and original net result.

LIMITS / The figures are hypothetical simulations using historical data and stated research assumptions. They do not represent live trading or guarantee future outcomes.

Case 02 · QQQ / MNQ

Dynamic exposure with an execution bridge

Can a long-horizon QQQ signal express variable exposure through MNQ while keeping execution costs, margin, and residual notional visible?

METHOD

The model combines EMA defence, all-time-high state logic, and percentile-based overheat controls. MNQ carries the primary notional while QQQ shares fill the residual exposure.

EVIDENCE

The reporting layer records target versus actual exposure, contract and share counts, costs, margin use, overheat states, and the largest drawdown episodes.

LIMITS / Results depend on historical prices, modelled commissions and slippage, and simplified execution assumptions. They are not live performance.

Case 03 · Strategy 1

Bad-regime risk gate

Can recent market structure identify environments in which a strategy is more likely to suffer, without becoming another entry signal?

03BAD REGIMEScore
04ON · REDUCED · OFFRisk state
METHOD

Out-of-sample closed trades provide the loss labels. Recent regime features are compared with a trailing baseline, ranked by loss lift, and combined into a BadRegimeScore.

EVIDENCE

The output is a transparent risk state — ON, REDUCED, or OFF — evaluated through avoided loss, missed profit, net gate effect, drawdown, and threshold stability.

LIMITS / A gate is accepted only when multiple diagnostics agree. If missed profit exceeds avoided loss, the report states that directly.
