多空比率 (Long/Short Ratio)
I found fairly good system using pivot points. What bother me is the 1 to 4 short/long ratio.
Analyzing 2 years back of the almost any stock market index around the world will not be so realistic due to the bull market we are in.
Is a system that produce this kind of results can still be reliable? should I get data of the market before 2003? will results that base on this data will mean something?? or maybe the market has changed since then?
TIA,
Avihu
