Theta Workbench

The problem

Options position management often happens across too many disconnected surfaces: broker position tables, market-data pages, handwritten notes, screenshots, spreadsheets, and AI conversations. That makes it difficult to keep the full structure of a position in view while also understanding what changed in the underlying stock, how much extrinsic value remains in each leg, and what context should be exported for further review.

The harder problem is not calculating payoff. It's maintaining a coherent decision workspace during active adjustment cycles. Without a dedicated tool, the operator has to manually reconstruct option legs, quote context, trendlines, moving averages, and prior analysis each time a position is reviewed. State scatters. Analytical context is lost between sessions. The working notes — which legs were entered when, which trendlines were drawn where, which projection scenarios were considered — exist nowhere durable.

The system

Theta Workbench is a ticker-centered analytical workspace. The operator loads an underlying, defines or imports option legs, inspects payoff behavior, reviews stock-history context, and prepares structured diagnostic or AI-review exports. State and analytical layers are per-ticker; switching tickers preserves each ticker's individual leg structure, trendline set, and overlay configuration.

Major working surfaces:

• Position and leg workspace — multi-leg option structures with entry context, role-aware leg analytics, intrinsic and extrinsic values, and leg-health summaries
• Payoff and history views — payoff visualization plus historical price charts with moving averages, user-drawn trendlines, Fibonacci overlays, and chart annotations
• Volatility and roll context — adjacent expiry and strike views, implied-move context, and roll-support information for adjustment review
• Diagnostics and exports — structured JSON diagnostic exports and AI-review prompt exports for downstream analysis
• Workspace persistence — encrypted .twb workspace backup as the durable save mechanism; browser session restoration for refresh-resilient working state

Before / After

Before: option review depended on broker screens, screenshots, manual notes, scattered AI prompts, and analytical state that was always slightly stale. After: position structure, chart context, leg analytics, and review exports are organized in one ticker-centered workbench, with the durable working set preserved in an encrypted local backup.

Technical context

theta.scvdata.com serves the live browser application, not a historical reconstruction. Visitors can review the workflow through representative or user-entered structures, while user analytical state remains client-side. Theta Workbench is a single-file HTML application with a small serverless function backing upstream quote retrieval. User analytical state — option legs, trendlines, Fibonacci levels, annotations — is processed client-side; SCVdata does not store or proxy user analytical state. Quote data is retrieved via the serverless function, which proxies read-only market data from upstream providers. Workspace state can be exported as an encrypted .twb file for durable local backup, using passphrase-derived key derivation. A separate JSON diagnostic export is available for state inspection — diagnostic only, not a backup format.
