Transition

From WhenToTrade to Cycles IQ

The Cycle Tools, the analyzer web app and the Cycle Analysis API that WhenToTrade built since 2019 continue as Cycles IQ. Same owner, same methods, same API keys. The whentotrade.com pages the app used to link to have been retired; this page tells you where each of them went.

Membership and pricing

The old "Cycle Tools" memberships and the trial versions are no longer sold. The analyzer and the scanner pages are now part of the Cycles IQ Membership, by invitation. The Cycles IQ API, the former Cycle Analysis API, is booked separately, pay as you go, once it opens after the invitation phase. Members of the Foundation for the Study of Cycles keep signing in on app.cycles.org with their cycles.org login.

For long-time WhenToTrade users: Cycles IQ brings the whole stack into one membership, with the advanced analyzer and the scanner pages, full API and MCP access, the Cycles AI skills, the Knowledge Graph as it is built, and sessions with Lars. Request an introduction or read what membership includes.

What is open without membership: Other ways in on the home page.
