Vortex Windows & Vortex Excel give identical trading results. In regards to interest accumulation Vortex Windows gives a $ 3 higher interest total for the full period @ 2% annual interest rate as input parameter. This is due to a slightly higher annual interest base rate to calculate the actual amount of interest earned each time a new date is registered.
Vortex Windows appears not to use the time averaged (ROTAI) Yield Equation at this time, although ROTAI was used as a basic yield representation indication in the development of Vortex Windows as it is the equivalence of the Internal Rate of Return which gives a much more realistic investment yield figure for time variable investments.
Per April 21-2012 we have removed some minor errors that were encountered.
