It is paramount to have a metrics of the degree of bullishness or bearishness of the market. Too much bullishness precedes a top, too much bearishness signals a bottom. We publish everyday a Relief/Worry index that gives a precise idea about where the market is. A reading above 2, then a lower figure, indicates worry. A reading beneath -2, then a higher one, signals relief.
To be completely honest it looks like a pretty unserious and scam-ish website. Reminds me a bit of those "Follow my method TODAY and earn 10000$ per day!". If it is a serious website, I suggest updating the design of it.
By the way the RW index is published for free and for everyone to see. So your point is not fair. Not a method in itself, just a tool with a precise purpose.
