Hi Tom 0 Safe and Sell/Buy settings of 9.09 & 11.11 These are from Don Carlson's 'Magic Formula'! I searched the board for the context of the conversation around these, but didn't find it. Maybe it was on the old board. These 2 above effect a 10% Price Move either side. Divide each by 2 for Split Safe/Minimum approaches. I dug out my old spreadsheet for the actual formulas. I think reciprocals are involved. (The PM% defines Price Movement) Buy Side =(1/(1-PM%))-1 Sell Side =1-(1/(1+PM%))
