Question:
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}

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.
=================================

CURRENT Question:
Okay! So, that's the old post. Here's my question ...
How do I put those red cubes at the bottom of my charts which would specify the following:
A simplified example would be:
B (buy) = RSI(14) above 90
S (sell) = RSI(14) below 20

A lot of peeps add those red blocks to the bottom of their charts, but I don't know how to do it.
Anyone who knows how to do this -- I'd appreciate the assistance.

karen, they're just using variables. oo and rr can be replaced with var1 and var2 or x1 and x2 or whateveryouwant1 and whateveryouwant2.

If you post the Boolean filter and what modifications you want I will try and explain.

As for your current question, to draw the blocks at the bottom here is how I do it:

Fetcher[

/* Always put your indicator in a set statement with count. */

/* RSI(14) above 90 turns into: */
set{BUY,count(RSI(14) above 90,1)}

/* RSI(14) below 20 turns into: */
set{SELL,count(RSI(14) below 20,1)}

/* If you want the marks regardless if they hit today or not: */
BUY > -1
SELL > -1

/* If you want just BUY signals, change above to BUY > 0 */

/* If you want to show tickers only with a BUY or SELL signal today, uncomment the lines below */

/*
set{trigger,BUY + SELL}
trigger > 0
*/

draw RSI(14)
draw RSI(14) line at 90
draw RSI(14) line at 20
]

I don't see any blocks.

They're there, just not on all tickers. The boxes only appear if they broke RSI(14) 20 or 90 within the last 3 months.

Does this work for you ? .. or is something missing?
I don't understand where I've told it to put in those cubes.

Fetcher[
set{SELL,count(RSI(14) above 80,1)}
set{BUY,count(RSI(14) below 20,1)}


set{trigger,BUY + SELL}
trigger > 0
BUY > 20,1
SELL > 80,1

Apply symlist(AAPL, AMZN)
add column rsi(14)
]

If you want to see when the conditions hit for those tickers:

Fetcher[

set{SELL,count(RSI(14) above 80,1)}
set{BUY,count(RSI(14) below 20,1)}


BUY > -1
SELL > -1

Apply symlist(AAPL, AMZN)
add column rsi(14)
draw rsi(14) line at 80
draw rsi(14) line at 20
]




If you want to show only when one of those conditions is true today:

Fetcher[
set{SELL,count(RSI(14) above 80,1)}
set{BUY,count(RSI(14) below 20,1)}


set{trigger,BUY + SELL}
trigger > 0

Apply symlist(AAPL, AMZN)
add column rsi(14)
draw rsi(14) line at 80
draw rsi(14) line at 20
]
