This is not investment advice

QuantEngines is a research and analytics site. Everything here — screeners, backtests, signals, strategy validation, congressional trading analysis — is published for information and education. None of it is a recommendation to buy or sell any security, and none of it is tailored to your circumstances.

We are not a registered investment adviser, broker-dealer, or financial planner, and no content on this site creates an advisory relationship. Before acting on anything you read here, consider speaking to a licensed professional who knows your situation.

Past performance means very little

Backtested and simulated results are hypothetical. They are computed with the benefit of hindsight, they do not account for slippage, liquidity, taxes, or the emotional reality of holding a losing position, and they are not a promise about the future. A strategy that tested well can lose money immediately and permanently.

You can lose some or all of the money you invest. Options and derivatives can lose more than you put in. Only risk what you can afford to lose entirely.

Where our data comes from, and how it can be wrong

Congressional trading data is derived from public periodic transaction reports filed with the House and Senate under the STOCK Act, published at house.gov and senate.gov. Market data is sourced from third-party providers including Polygon.

  • Filings are self-reported and are often submitted weeks after the trade. What you see here is a record of a disclosure, not a live trade feed.
  • Filed amounts are ranges, not exact figures. Any total we show from them is an estimate.
  • Filings contain errors, amendments and omissions. We reproduce what was filed; we cannot verify that a filing is accurate or complete.
  • Third-party market data may be delayed, incomplete or incorrect, and we do not guarantee it.

A disclosed trade is not evidence of wrongdoing by anyone named on this site. If you believe something here is wrong, tell us — see our Corrections Policy.

No warranty

The site and its tools are provided "as is", without warranty of any kind. We do not guarantee that the site will be available, accurate, or uninterrupted. To the fullest extent permitted by law, we accept no liability for any loss arising from your use of this site or reliance on anything published here.
