Tollbooth Infrastructure

Purpose-Built from Scratch

Tollbooth doesn't run on top of any third-party trading platform. Every component is custom-engineered for covered call optimization.

Data Infrastructure

Custom servers in private data centers processing pricing data on approximately 2 million option chains twice per second.

  • Primary: Schwab Streaming API + Polygon.io
  • 10+ supplemental data sources
  • Sub-second latency for trade signals

Security & Connection

Account connection via OAuth token through Schwab's public API. No username or password is ever shared.

  • Scoped authorization — order placement only
  • Weekly token refresh on Sundays
  • No transfer or withdrawal capabilities

Order Execution

All orders placed as limit orders — never market orders. Patient, opportunistic fills that minimize market maker cost.

  • Priced slightly above the ask
  • 20–30% fill rate by design
  • Incremental step-down after 5 attempts

Deterministic Logic

No AI in trade decisions. Every order can be fully explained with a specific, auditable reason.

  • 12,000+ workflow rules and conditions
  • 3,700+ automated tests per deployment
  • Complete audit trail for compliance

Strategy Edge

Why Weekly Options Outperform

Theta decay accelerates as expiration approaches. Tollbooth's scoring engine consistently identifies weekly options as the higher-return choice.

Non-Linear Theta Decay

When comparing net credit on a 7-day option versus a 30-day option against the same underlying, the 7-day option typically shows a higher annualized return. Tollbooth consistently identifies weekly options as the higher-return choice.

vs. Static ETFs

Covered call ETFs like TLTW and NVDY sell monthly fixed-schedule calls regardless of conditions. Tollbooth's preference for weekly options is one of the largest single contributors to its 4–32% annualized outperformance over those benchmarks.
