I have a question regarding placing a "buy" and "sell" point on the
Summation Index.
I presently use a 3 days down or 3 days up from the hook or extreme
point peak point( 3 dots or 3 period time frame) to generate
my "buy" or "sell" signals. Basically I want to check the most
extreme points on this graph and compare in the last 5 trading days
if that's the extreme low point or the high point on the graph.
If that's true I want to "buy" or "sell" based on the SPX index.
I also use "yahoo to down load data" end of day...what do I need to
change in the AFL codes to get this script so it works?
I think on decisionpoint they use a 10 day period crossover for a
buy or sell on the Summation Index...but I think its way too long
and conservative.
Thanks!
