FatTail App

📊 FatTail App — Platform Training

The FatTail App is a dedicated options analysis platform built from the ground up for 0DTE structural trading — and it has crossed a threshold: the full trading loop is now live, end to end.

The app follows Apple’s Human Interface Guidelines with a Liquid Glass look and feel. It’s built around one always-visible workspace in the center — the main content area where you analyze options strategies — flanked by two sidebars you show or hide as you work: a Routine sidebar on the left (in development) and a Process sidebar on the right (your Trade Log, Journal, and Reports).

The FatTail App: a central workspace flanked by the Routine and Process sidebars.

Prepare → Execute → Reflect is no longer just the routine. It’s the software. Spot convexity on the Heatmap, build the position, analyze it on the Risk Graph, submit the order to the built-in MSC Brokerage, and watch the fill land in your Trade Log automatically — realized P&L, per-leg fills, performance reports, and your Journal, all connected. No spreadsheets. No manual imports. The app closes your feedback loop for you.

This course teaches you to run that loop station by station:

• 🔥 The Convexity Heatmap — read skewed risk/reward across the whole board at a glance, and turn any tile into a live position with one click
• 📈 The Risk Graph — every bit as capable as ThinkorSwim’s Risk Analyzer, with capabilities ToS doesn’t have: probability bands with a multi-σ ladder, Market/Theoretical vol modes, dealer-positioning backdrops (GEX, Volume Profile, zero-gamma zones), and a what-if time machine
• 🧊 The 3D Surface & Price/Time views — the same pricing engine rendered across price and time, now supporting every structure including calendars and diagonals
• 🎯 Submit & Order Flow — execute the full submit → fill → close cycle against the built-in MSC Brokerage with zero capital at risk. Your training ground for reps that count
• 📒 Trade Log & Reports — your book of record: equity curve, win rate, profit factor, expectancy, drawdown, strategy and time-of-day breakdowns
• 📓 Journal & Playbook — where reps become method: session-by-session journaling with your actual fills pulled in automatically, and a playbook that turns evidence into rules
• 🔔 Alerts — most price, greek (Δ/Γ/Θ), and position alerts are live, evaluated against your positions in real time; dynamic trailing alerts and algo alerts are in active development
• 🧠 Vexy — the cognitive layer woven through it all: not a chatbot, a reasoning surface wired to your positions, your journal, and the doctrine (a work in progress)

The focus never changes: seeing where convexity exists — not being told what to trade. 👁️

The app remains in perpetual development — new capability ships regularly, and the What’s New module keeps you current with each release. What’s live today is taught as it actually works; what’s coming next lives on the roadmap, not in the lessons. ✅
