I cant say why there isnt much interest in it, it is a great technique. I use it on the lower TF, typically 5 to 15, i use it in combination with the 50EMA. I use the longer term to carry the trade, but mostly now i use the 15 min TF. Price action rules, on daily trading, and indicators like the stochs are too slow, but on the 4hr and upwards are good.
