What is dark pool trading and why does it matter for stock analysis?

Dark pools are off-exchange trading venues where large institutional orders execute away from public markets. StonkWhisper tracks FINRA-reported dark pool volume to identify unusual institutional accumulation or distribution that may precede significant price moves.

How does StonkWhisper track congressional stock trades?

The STOCK Act requires U.S. Congress members to disclose personal stock trades within 45 days. StonkWhisper monitors these mandatory disclosures in near real-time, surfacing trades by legislators who may have non-public information advantages.
