Hi Toofuzzy, I suddenly remember that the way the percentage was calculated in the spreadsheet is not the standard way. We had this discussion a while back where I questioned the percentage calculation method.
What I was taught, for calculating a drop, was to divide the lower price by the upper price. I.e., 8.33/10=0.833 then subtract from 1 to get the percentage drop, like you did, in this case, 16.67%.
The spreadsheet is set up differently and I've never quite figured out what it does or how it does it, I've just adjusted my percentages to get where I want, 20% in actual dollars. In this case to get to an $8.00 buy price I have to use 14.85%. Mostly I just use 15% instead of 10% buy safe.
Interestingly enough Steven R. Selengut says don't buy until there is a 20% drop in price and sell when there is a 10% rise.
Best,
Allen
