In the Tradescript Help Manual there is a use of the keywords
"FIND STOCKS WHERE"
for eg: in page 81
Parabolic SAR / MA Script
# Buy if the MAs crossed today or yesterday and
# if the PSAR crossed today or yesterday
FIND STOCKS WHERE
(CROSSOVER(CLOSE, PSAR(0.02, 0.2)) OR
CROSSOVER(REF(CLOSE,1), PSAR(0.02, 0.2)))
(CROSSOVER(EMA(CLOSE, 10), EMA(CLOSE, 20)) OR
CROSSOVER(REF(EMA(CLOSE, 10),1), REF(EMA(CLOSE, 20),1)))
My Question is, if the EAs are specifically meant for running on individual securities / charts, then what is the use of using those keywords (Find stocks where).
is it something that we can use in the scanner code?
Please elaborate on your answers, on why, where and how to use these keywords.
