Thanks, Steve, for the warm welcome. The turnips themselves are indeed a variety of indicators, but the various maps (long term, medium term and very short term) use special regression analysis equations, also known as "correlation transform". The place were intuition and experience comes into the equations is how to vary the coefficients as cycles advance and change from bullish, to neutral to bearish. Even with all the efforts to keep the system current, the basic facts that the market changes cause change in those equations, and with all efforts, the turnips still fail a good part of the time. Sometime the equations are really well tuned (like from the call on April 22nd to a bearish stands, once the expected rally, failed to take us above 1830, and then the support at 1770 failed), others, like last December, or even during March and April, the turnips were less than perfect. The interesting thing in the first half is that the model set up on December 29th, needed very little corrections, once the April rally failed to get under way, all had to do was to subtract from the December 29th model, the amount of the "failure" (about 300 Naz points, about what the February low was below the original Dec 29th plan) to get quite correctly the rest of the first half.
