TradeEngine

Decide what you want to earn. The engine computes the path.

Every setup runs through thousands of simulated futures before risk is committed. Monte Carlo turns an edge into a win rate, a win rate into risk parameters, and risk parameters into an expected return you can choose — directly in the options chain.

Each tick is one trade from a 57% edge. Monte Carlo replays this thousands of times to estimate the stable win rate and equity curve before capital is committed.

II/Data processing

How the engine processes data before a trade is sized.

The Warehouse publishes volatility, drift, regime, flow structure, and win-rate priors. The Monte Carlo layer consumes those inputs, runs thousands of seeded simulations, and emits a full distribution — not a single forecast. That distribution is what sets risk parameters and prices the chain.

III · Simulation

Thousands of futures, not one forecast.

Geometric Brownian motion draws path after path from the asset's volatility and drift. The engine keeps every step — median, likely band, and tails — so you see the full shape of what could happen over the horizon, not a single price target.

IV · Distribution

Every outcome, counted.

When the simulations finish, terminal prices collapse into a probability distribution. That histogram is the object the engine reads — where mass clusters, where the tails sit, and how much of the future finishes above or below spot.

V · Risk parameters

The distribution becomes your risk parameters.

Expected price, probability of finishing up, outcome bands, downside tail, and Kelly-optimal size all fall out of the same simulated record. No round numbers, no gut feel — just statistics from the futures you already ran.

VI · Options chain

Pick how much you want to earn.

The same distribution prices every strike. Black–Scholes supplies premium and delta; Monte Carlo supplies P(ITM) and expected return. Choose the payoff you want — the engine shows the trade that targets it and the odds you are paying for.

VII/The quantitative stack

One engine, every model, one scorecard.

TradeEngine is powered by @gx/analytics — a shared Monte Carlo core surrounded by Black–Scholes, Kelly sizing, GARCH volatility, Bayesian signal fusion, and a master trade evaluation engine. The illustrations on this page run the same code path the terminal uses; what you see here is how the desk gets its numbers.

Trade evaluation

Win rate first

Historical edge and conviction replay trade by trade until a stable rate emerges — live in the hero simulation.

Risk second

The distribution sets bands, tails, and size before any order is staged.

Return last

Every strike carries modeled P(ITM) and expected return so you pick the outcome, not guess the path.
