I am looking for an easier way than full rewrite of an existing filter. What I want is my filters shifted back 1 day ...e.g.
FROM x, y, z days ago /volume/price TO x+1, y+1, z+1 days ago/volume/price.
One application of the above would be tweaking a Muddy filter (like the one below for 3 day tail), so that by adding "and close is above close 1 day ago", you get a green day after all the down days. This filter might then improve one's chances of catching a stock upside, as opposed to watching for a green the next day before entry.
Of course the next step would be to do a backward/forward for a given number of days more than 1.

siliconhippy,
There's always the "offset 1" phrase... Does this do what you're looking for?
It'd be *really nice* if SF allowed set{} variables in the "days ago" phrase (and other places a number of days can be used)...
HTH,

cegis,
I believe the "offset 1" phrase only gives you a backtest feature. What i am looking for is to shift my existing filter by 1 day in the past, and then add a phrase that will give symbols that turned turned up in the price the last day.

siliconhippy,
Ahhh, you want values after the shift. Now I understand...
Unfortunately, the only way I'm aware of doing that is with the "days ago" feature.
Shore would be nice if'n SF would allow the use of variables in the "days ago" phrase...
