02 / THE WORKSPACE

Depth in the detail.
Context around it.

A question rarely stops at one view. Follow it from the business to the instrument, through the event and into the wider market.

01 COMPANY / CONTRACT

From the company
to the contract.

Company quotes, price charts, news and available fundamentals connect with option chains, contract comparisons, flow and modeled exposure.

QUOTESCHAINSFLOW
02 EARNINGS / EVENTS

The next event.
The history around it.

Earnings calendars and historical reactions sit alongside public-source event records. Dedicated engines organize event-related contract research.

03 CONTEXT / CONTINUITY

The wider market.
A continuing thread.

Brief, Markets, Macro and Bonds & Fed add context. Watchlists and saved setups keep the research available as the questions change.

Modeled exposure is descriptive, not actual dealer holdings or a price prediction.

THE APPROACH / STRATEGY RESEARCH

Ideas worth investigating.

From equity behavior to volatility pricing and the wider market. Explore the questions behind established strategy families—and the assumptions that need testing.

Compare the movement priced into options with the movement that subsequently occurs. Any strategy must account for option premiums, hedging costs and losses during large moves.

A RESEARCH LANDSCAPE, NOT A LIST OF IMPLEMENTED STRATEGIES. Our engines have not established an investment edge. Gold indicates the selected topic.

An idea. A rule.
A result to question.

Watch a mean-reversion algorithm make decisions on a synthetic price path. Every trade follows a rule. Every result includes modeled costs.

01 / THE HYPOTHESIS

A price far below its recent average might recover. The algorithm measures that distance in standard deviations using the previous 30 one-minute observations. The glowing field shows the history behind that reference.

02 / THE RULES

Buy one unit when the z-score falls below −1.5. Exit on a return to the mean, a 1% loss from entry, or 30 minutes held. Decisions fill at the next observation; any remaining position closes at session end.

03 / THE FRICTION

A falling price can keep falling. Each fill costs 0.05% of its value, representing simplified fees and slippage. Net results include open-position gains and losses. Stops can fill beyond their threshold; losses remain visible.

Simulation assumptions & trade record

391 seeded synthetic prices, starting at $100; a 30-observation warm-up; one unit maximum; no leverage or shorting. Trailing population standard deviation excludes the current observation. No new entries in the final two observations. Fills use the following price plus a 0.05% cost; the scheduled closing liquidation uses the final price. This model omits liquidity constraints, market impact and taxes. P&L is in dollars, not a portfolio return or benchmark comparison. Particles show historical observations, not orders; diamond markers show fills.

The trade record appears as the session unfolds.

An implemented educational algorithm running on synthetic data—not an MST engine, market backtest or evidence of an investment edge. Parameters are illustrative. No claim of profitability or market outperformance.
