"That shouldn't result in you missing any trades - rather you just pay a higher price than you might otherwise have. Price dips, AIM suggests adding 10 more shares at $x, but you don't actually buy at that time. Next month no AIM trade indicated and you're 10 shares short, so you buy at the current price - which might be higher than $x. "
Say your stock drops below the hold zone. You don't follow advice of AIM but hold off and wait for your buy filter to kick in. The stock makes some recovery. Say it goes back into the hold zone (not an unlikely prospect) -- so with this advice you're making your buy of 10 shares at a price within the hold zone. Am I correct.
