Silvertrend formula

I have several Silvertrend indicators, all of which produce different results. I understand the basic theory - the indicator looks at the high/low of a certain number of bars and, based on the close of the subsequent bar in relation to the high/low/range of the preceding bars decides on a potential price move. Can someone explain (or point me toward) an explanation of the underlying formula?

Thanks,

there is a huge flaw in silver trend. it moves from current bar to the first bar in its calculations, so it is easier to find the tops and bottoms. in real life the market moves the other. i have reprogrammed it so it works the correct way, but now it doesnt really help at all. it also redraws the dots as it goes, so one second the signal might be good and a few seconds later its not. so in hindsight this is an amazing indicator, but in reality it is almost random, so use at your own risk.

as far as the calc the equation is pretty much: if the current price is Y% lower then (get the highest high of the last X bars) then mark it as a reverse.

Thanks for responding. I agree - ST is a very confusing indicator, appearing and disappearing the way it does. I've been testing a method that uses Silvertrend as a sort of "early warning" that a trade is imminent but it really is not essential to the correct functioning of the method. Just adds to my overall store of knowledge to understand how things work...
