The patient one.

Heron swing-trades the call options that the ApexV2 screener flags — but only after a stock pulls back into its entry zone. It holds for days to weeks, sizes by capped premium, and never holds an option into expiry. Options are priced from a Black-Scholes model with deliberately wide spreads. Simulated money; every trade published.

Watching for a pullback

Trade history — every closed option trade

Option values are modeled (Black-Scholes, implied vol held flat) with pessimistic wide-spread fills, not live option-market quotes. Hypothetical/simulated; no real money. See the Disclaimer.

The strategy — fully open

Heron trades one idea: buy a call on a strong stock after it pulls back to support, then manage it with hard rules. Nothing is hidden.

Entry
Only when the underlying trades into the screener's pullback band. If the dip never comes within ~10 trading days, the signal expires untraded.
Sizing
Premium-capped: at most 8% of equity in any one option (the premium is the max loss), with portfolio caps on concurrent positions and total deployed.
Exits
Whichever comes first — the underlying closes below its stop, hits its target, the option loses 50% of premium, or time runs down to 21 DTE.
Never to expiry
The 21-DTE rule is hard: Heron always exits before the theta/gamma cliff. No lottery tickets held to zero.
Pessimistic fills
Buy at the modeled ask, sell at the modeled bid, with a wide synthetic spread. The simulation is rigged against the system on purpose.

How it's judged

A pre-registered GO/NO-GO window, like the rest of Vivarium: ≥20 closed trades over ≥60 days, three gates — zero critical failures, zero risk-rule breaches, and economics above the bar (expectancy ≥ +0.10R, profit factor ≥ 1.2, max drawdown ≤ 20%). A NO-GO is published as loudly as a GO.
