I think I see what the problem might be, and it's probably a basic flaw in
my design. Alternating up and down price movements can repeatedly cross the
same percentage boundary, thus giving more signals. Now that I think about
it I'm guessing that you only want one signal per 1% increase in price. In
other words, a signal when the price crosses above a 1% boundary but no
signal it the price moves down then moves up through the same boundary
again. Am I on the right track now or was I right to start with, or still
completely wrong?
