Question:
Didn't SF at one time have a link for their Boolean filters?
i.e.,
I don't know what "qq" means. I don't know what "rr" means ...
I don't know what "oo" + "rr" means. (WHY are they adding "oo" and "rr"?)
SET{C1, oo + rr}
SET{C2, C1 +qq}
What would be the difference between "r" vs. "rr" or "q" vs. "qq"?
SET{rr, COUNT(r between 0.99 and 1,1)}
SET{qq, COUNT(q between 0.99 and 1,1)}
set{o, ma(20)/close}
SET{oo, COUNT(o between 0.99 and 1,1)}
set{r, ma(50)/close}
SET{rr, COUNT(r between 0.99 and 1,1)}
set{q, ma(200)/close}
SET{qq, COUNT(q between 0.99 and 1,1)}
add column c2{times}
sort column 5 descending
add column oo{ma20}
add column rr{ma50}
SET{rr, COUNT(r between 0.99 and 1,1)}{ma200}
SET{C1, oo + rr}
SET{C2, C1 + qq}
Question:
Some one else had a Boolean filter that put "Buy", Sell", 'Wait" cubes at the bottom of their charts. I believe it was color-coded.
I have NO clue how to do it. I copied their filter a few months ago, but couldn't modify it because I don't know Boolean.
Anyone gotta link?
Thanks in advance.

Short slide show on boolean logic...
To move to the next slide, tap the NEXT button it is located in the top-right corner.
From the slide show:
Available options: dog, cat, bird, fish
AND = BOTH (fur and barks = dog)
OR = EITHER or BOTH (feathers or scales = bird or fish)
NOT = ONE and NOT the other (lays eggs not in trees = fish)

The basic idea is to create two (or more) user-defined variables - let's say your two conditions are that the close price must be above the 20 day moving average and the rsi(2) must be below 5.
Now this is a really simple one since we could just write two filter statements and not get fancy, but here is a way to construct the Boolean versions:
set{variable1, count(close above ma(20),1)}
set{variable2, count(rsi(2) below 5,1)}
set{Boolean_AND, variable1 * variable2} - this returns a value of 1 only if both conditions are true
set{Boolean_OR, variable1 + variable2} - this returns a value of 1 if either condition is true
As to the filter which color-coded options - it might have been this one from me a while back:
