You still don't get it, let me spell it for you: When professionals in this market with years of training and work experience invested tons of money and time in their education and training then it is because some newbie indicators, overlaid with couple filters and buy and sell rules do not provide value-added. Everyone would be using them if they proved worthwhile. It is ok to challenge the status quo but if something completely goes against logic and common sense then maybe it should be questioned and taken for what it is, nearly worthless. I used professional bank traders as example. Hope this makes it clear now.
oh, iam not sure why were talking about them to begin with, were talking about sp500 n this,,,
by the way totally unrelated to this i wanted to thank u on ur advice in other post regarding hiring someone to code for back testing, its working so far good
