If you used lagging indicators for trading the S&P for the last say 6 month's you would have had your arssss handed to you. Indicators like that are a waste! Some times there right sometime there wrong. Stick to price because price doesn't lie. And if it does, which some may argue you will know the truth a lot sooner. It amazes me how many people search for dummy indicator like RSI, CCI, STO etc. These indicators were developed for one reason only. To take trades money. All you need is PRICE! Will go into further detail if needed later on.
