print(r.json())What is EFFECT?
When the SEC declares a registration statement effective, or qualifies a Regulation A offering statement, it posts a notice of effectiveness on EDGAR with the EFFECT form type. It is a short notice, but it marks the moment securities can be sold.
For IPO tracking, the EFFECT notice for an S-1 or F-1 is usually the day before pricing, which makes it a precise timing signal.
Issued by the SEC staff, filed under the registrant's CIK.
On the date the registration statement or offering statement becomes effective or qualified.
