# Backtesting Although Aegis begins monitoring an address only after it is added to the watchlist, any past time period can still be analyzed using our backtesting feature. Users can glimpse valuable insights into the cause and timing of past security breaches, identify overlooked vulnerabilities, and take preemptive steps to mitigate potential future risks. Please note that the time period for backtesting is limited to 24-hour intervals due to strains on Aegis infrastructure. Backtesting is not available to free-tier users. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.lossless.io/aegis/introduction/how-does-aegis-work/backtesting.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
