Feature PRO
From thesis to trade in one flow.
Give Trade Builder a thesis (long AAPL, want 20% upside by Q2, willing to lose 30% of premium) and it returns a ranked list of structures with strikes solved, credit/debit calculated, and a P&L grid across spot × time — every trade fits your view AND your risk budget.
How it works
- Pick a ticker & horizon. Or open Trade Builder from a Radar hit / Options Pulse anomaly — it pre-fills.
- Describe your thesis. Direction, magnitude, timing, conviction. Or click "Auto-suggest thesis" and Erina synthesizes one from the evidence pack.
- Get structures. The suggester returns spreads, calendars, condors, butterflies, straddles — whatever matches the thesis. The strike solver picks strikes that hit your target P&L profile.
- Inspect the P&L grid. Every candidate shows P&L across spot × days-held, plus max profit, max loss, breakeven, and probability of profit.
- Save as a candidate. Layer B tracking — daily P&L snapshots, status transitions, and a close modal when you're done.
Idea sources
- Anomalies — from Options Pulse rows.
- Earnings — LLM-driven, cited context on IV term structure, historical moves, seasonality.
- Technical setups — RSI/MACD/breakout patterns.
- Portfolio-aware covered calls — from your existing long positions.
- Ask Erina chat — "give me trades for CRWD earnings" opens Trade Builder pre-loaded.
What makes it different
Every structure passes no-arbitrage credit gating and no-silent-skip guardrails — if a leg can't be priced cleanly, you see why, not a mystery empty list. The strike solver uses BS reprice with solved IV+greeks; the P&L grid uses the same math the portfolio tracker uses at settlement.
