Method note & pre-correction baseline (reset 2026-07-26)

Post-reset research sample (unique markets, last write wins; path $ from equity series only). Pre-reset archive PDF remains for method notes.

Download pre-correction research baseline (PDF) - estimator error, correction, and pre-correction aggregates (no trade tapes)

Capacity evidence (Phases 0-4)

Parallel microstructure study (Level-2 snapshots → VWAP penetration → fill/footprint models → multi-window schedule → Path P&L under size caps). Complements 1-contract shadow Path P&L for edge discovery; does not scale that path linearly. Frozen shadow exit policies are unchanged.

Research edge discovery (1-ct shadow) → capacity evidence layer (L2 → VWAP → footprint → multi-window → liq-cap Path P&L) for buyer diligence.

Live outcomes-

Provisional: treat win rates and hybrid deltas as research evidence. Exit policies stay shadow until a dated re-eval. Freeze gate: 20 to 30 win65 first_hot unique tickers (one first_hot row per market, strictest gate).

Calibration snapshot (provisional)

High-level mid-window forecast quality on unique settled markets only. Research-only; not a claim the model is ready for live trading.

Shadow WR = entry current_exit on unique markets (not window-path +rate). Model research-post-reset. Path $ = equity-series sum (unique last-write windows). Not audited · not a solicitation to trade.

Cumulative path P&L (1-contract baseline)

Unique markets, last write wins · simulated cooldown path · anonymized window order. Closed trades from outcomes log are never included.

Max drawdown -
Longest losing streak -
Path +rate (incl. flats) -
Path +rate (active only) -

1-contract cooldown sim path. Flats (no trade) count against “incl. flats” only.

Rolling path +rate (active windows)

Share of the last N non-flat (active) windows that were positive. Flats are omitted from this series. Not Shadow WR.

Entry threshold (min predicted win probability)

Aggregate mean shadow P&L per entry when the confidence bar for an entry is raised or lowered (cooldown, 1 contract). Counts and win rates only - no individual signals.

Shadow exit comparison

Same first_hot markets under alternate exit rules only (1-ct, est. fees). Primary counter: cumulative Δ total $ for the leading policy vs current exits (lead can change as the sample grows). One row per market ticker · anonymized entry order.

Solid lines: cumulative shadow P&L by exit policy. Thick dashed line: cumulative Δ$ for the leading policy (shadow − current). Hover a line to focus it; Reset view (KPI row) restores all series. Not live trading.

Running average Δ¢ per entry for the leading policy (positive = shadow beating current so far).

Avg P&L by exit policy

Cheap-open scalp

Isolated paper path. Enter only in the first minute when a side is well below even money. Brain/model does not decide whether to go in. Hold a short time and stay only while still green. Reconstructs the pre-automation operator style. Not Shadow WR. Not live trading.

Cumulative 1-contract paper P&L in anonymized close order. Own book: does not enter first_hot Shadow WR or live calibration.

Shadow path $ -
Shadow avg -

Same 1-ct size. Shadow line is the equal-weight mean of Shadow exit comparison policies on the first N unique first_hot closes, where N is the live scalp sample. The scalp path is not in that mean. Different entry book: not the same trades. Hover a line to focus it. Reset view restores both series.

Instrument and method

Venue (context only). Kalshi is a CFTC-regulated U.S. exchange for event contracts. KXBTC15M-style markets are short-dated binaries on BTC vs a strike over a fixed interval. This page does not republish live books, quotes, or market-by-market rows.

Research process. Internally we estimate win probability and apply thresholds and risk rails. Public charts show anonymized shadow-path aggregates (cumulative P&L, rolling win rate, threshold bars, shadow exit comparison) plus closed-trade side counts - not downloadable trade tapes or window dumps.

Publication scope. Personal non-commercial research summary. Speculative risk remains; capital can be lost. Not investment advice.

Who we are

Martial Systems LLC - quantitative research on short-dated event contracts.

Investor inquiries: martialsys@gmail.com

Terms

Event contract

Exchange-listed contract that pays on a defined outcome at a fixed time (here: BTC vs strike after 15 minutes).

YES / NO

Contract sides on binary event contracts. Public stats show aggregate side counts and win rates only.

Predicted win probability (p)

Model estimate that the chosen side wins by settlement. Thresholds such as p ≥ 70% filter weaker signals.

Cooldown

Minimum wait after an entry before another entry is counted on the baseline path.

Shadow WR (entry)

Share of unique first_hot markets with positive current_exit P&L (1-ct). Not path +rate (which includes no-trade windows).

Path P&L ($)

Equity-series sum of the 1-contract cooldown sim path on unique last-write windows. Excludes trade_outcomes closes.

Live vs path

Path is simulated research only. Live P&L is closed outcomes log aggregates. No per-trade tape is shown.

Aggregate-only public feed

No tickers, strikes, settle spots, entry prices, signal counts per window, or CSV downloads on this site.

Capacity program

Phased diligence layer: L2 book snapshots → VWAP pot-ladder EV → footprint gates → multi-window capital → liquidity-capped Path P&L. Proves scale without linear 1-ct × N math. Legacy shadow exits remain frozen.

L2 (Level-2) depth

Volume available at each price tick on the bid book (Kalshi). Public site shows snapshot counts only; full ladders stay on research hosts (disk-only).
