Realistic Fill Backtesting Engine for Options
A SaaS backtesting and alert validation platform that defaults to realistic bid/ask fill assumptions instead of mid-price, allowing options traders and alert service operators to measure true strategy performance. Includes historical spread analysis by strike and moneyness, real-time spread monitoring, and auto-filtering of untradeable setups.
Warum das wichtig ist
You run an options alert service or actively backtest strategies, and your numbers look fantastic on paper — 90% win rates, +20% average returns. But when you actually trade your own signals, buying at the ask and selling at the bid, the spread devours your edge and you are left at breakeven. The far-OTM plays that looked brilliant in backtesting are the worst culprits: market makers widen those spreads to absurd levels during moves, making them untradeable despite correct directional calls. You have started manually logging spreads and filtering to near-the-money strikes, but you have no automated way to validate whether your alerts are actually tradeable at realistic fills before publishing them to subscribers.
- · Entwickelt für Semi-professional options traders and options alert service operators who need credible, fill-realistic performance metrics for their strategies and subscriber-facing reports.
- · Wahrscheinlichste Monetarisierung: SaaS subscription with tiered pricing based on alert volume and number of strategies backtested.

- Design simple web dashboard showing mid-price vs. realistic-fill performance comparison
- Build API endpoint to ingest strategy parameters and return fill-realistic backtest results
- Add historical spread database with filtering by underlying, strike, DTE, and moneyness
- Implement auto-filtering that flags and removes untradeable far-OTM setups from backtest results
- Create alert grading report that operators can share with subscribers showing realistic fill metrics
- Build comparison view showing strategy performance across strike zones (far-OTM vs. near-ATM vs. ITM)
- Add real-time spread monitor that checks current spread conditions before a signal is published
Differenzierung
Warum dies scheitern könnte
Selbstwiderlegung — das wichtigste Vertrauenssignal
- 1Premium options data feed costs ($500-2000/month) may make pricing prohibitive for individual traders, squeezing margins before reaching scale
- 2Established backtesting platforms like Thinkorswim, TradeStation, or OptionAlpha could add realistic-fill features relatively quickly, neutralizing the differentiation
- 3Options data licensing restrictions may prevent redistributing spread analytics to subscribers, limiting the alert-service-operator use case that has the highest willingness to pay
Evidenzzusammenfassung
Wie KI diese Erkenntnis synthetisiert hat — keine wörtlichen Zitate
Approximately 8 commenters described the core problem: strategies and alerts that look excellent at mid-price become breakeven or negative at realistic bid/ask fills. Multiple users confirmed they manually track spreads alongside signals and filter to near-the-money strikes to preserve tradeable win rates. Several noted that far-OTM contracts are the worst offenders, with market makers widening spreads dramatically during moves. The discussion revealed that no automated solution exists for validating alerts at realistic fills — users are doing this manually with spreadsheets and ad-hoc logging.
