How much the price will go?

IAfter taking a position all investors, particularly the new ones, are pushed to think `now how far the price will go?' And the question pops up so frequent that in a forum (bollinger) once I could not control  myself and wen into action (as i`m an admin). With this post I giving codes of an AFL, collected from Net, that will help investors in finding the answer, `how far my stock price will go.'
