⚠️ Platform provides T-1 closing data only. No real-time quotes. Focused on long-term daily strategy backtesting.

Disclaimer & User Service Agreement

Platform Data Rules

1. All options and stock data are T-1 previous trading day's market closing data static snapshots. No real-time quotes, tick data, or intraday trade data provided.

2. The platform has no earnings database, no corporate announcement crawler, no macro event (FOMC, press conference) data. All backtesting models are based purely on daily price, volatility, and volume metrics.

3. Historical data has inherent limitations: split, dividend, and contract rollover adjustments are standardized and cannot fully replicate real trading slippage, fees, or dynamic margin changes.

4. Data is for personal academic research and long-term strategy historical statistics only. Not suitable for intraday trading decisions.

Not an Investment Advisor — Does Not Constitute Investment Advice

1. OptionEOD provides only historical data tools, a backtesting simulator, and data export API. The platform and its operators hold no financial licenses and are not registered investment advisors, brokerages, or asset managers.

2. All strategy templates, backtesting results, and charts are objective calculations of historical data. They do not represent future returns and do not constitute buy, sell, hold, or hedge recommendations.

3. Options are high-risk derivatives with the potential for total loss of principal. All live trading decisions are the sole responsibility of the user.

Historical Backtest Results Risk Warning

1. Backtesting has inherent biases: no intraday slippage, no financing costs, no dynamic margin adjustments, and cannot simulate black swan intraday events.

2. The platform does not support event-driven strategy backtesting. Volatility gap losses from earnings, policy changes, or breaking news cannot be reflected in the model.

3. Past profitability does not guarantee the same returns under identical market conditions in the future. Market structure and volatility cycles change over time.

4. Users should not rely solely on backtesting performance as the basis for large real-money trading decisions.

Platform Function Boundaries & Service Limitations

  • No real-time quotes, no intraday alerts, no 0DTE/intraday backtesting capabilities.
  • No broker API integration, no auto-trading, no live trade execution functionality.
  • No earnings, macro event, or news database.
  • No human investment analysis, strategy guidance, or stock recommendations.
  • Data updates may be delayed due to data source provider latency or server maintenance. The platform does not compensate for any losses caused by data delays.

User Responsibility

1. Users shall not use platform raw historical data, offline packages, or API data for commercial redistribution, resale, or building competing SaaS products.

2. Crawling or bulk automated API requests are prohibited. Violations will result in account restrictions and API access revocation.

3. Users are responsible for their own account credentials. Data leaks or subscription losses due to account lending or theft are the user's responsibility.

4. Persons under 18 years of age are prohibited from registering or using paid plans for financial research.

Limitation of Liability

The OptionEOD operator bears no liability for any direct or indirect financial losses arising from, including but not limited to:

  • Data delays, omissions, or adjustment biases causing distorted backtesting conclusions.
  • Server maintenance, network failures, or third-party data source interruptions causing temporary service unavailability.
  • Users executing live trades based on platform backtesting results and incurring losses.
  • Inconsistencies between third-party broker or external tool data and this platform's data.
  • Copyright or legal disputes arising from unauthorized data distribution or resale by users.
  • Other unforeseeable risks and liabilities applicable to this backtesting system that are not explicitly listed in this disclaimer.
