This article is a bit misleading. Nobody trades on a TA alone ignoring the reality around. That just doesn't happen. TA is an indicator, a raw information. It's up to you what you make of it.
Also: the cross SMA strategy the author mentions is indicative of one of the basic forces of market and works very well on certain markets.
Also: nothing actually works on SPY, it's the most efficient market there is.
It seems short term efficient but over the longer term there are periods where putting all your money into it are in fashion and periods when the public are wary of stocks.
