The only place to get a written definition for the various market timing rules (that I could find) is hidden behind the Portfolios tab.... PortfolioS>My Portfolio>Edit>Build a Custom Trading System>And finally to a screen that explains market timing. Should this not be front and center on the Home Page so that everyone knows what each of the systems are. I had someone from Support send me a cheat sheet (attached) showing all of the various timing signal rules. This was very helpful and should be posted on the home screen given that VV is touted as market timing software.
