Billy,

Thank you for the great responce. This really helps with my understanding.

You mentioned:

But the “most probable” 3-day target if you have the opportunity to enter at the limit entry price of 85.10 is:
85.10 – (85.10 * 2.64%* 61.67%) = 83.71

Once again, it's my age! :) but where does the 2.64% and 61.67% come from?
