DeMark indicators in Bloomberg

Anyone rely on these, specifically TD Sequential or TD Combo? What do you think?

I am a buy-side trader at a super regional and I use sequential. Perfect setups are rare and as expected stocks rarely do what TD forecasts but I find it useful.

I took his class at the bloomberg office in SF; but I can only take soo much fibonacci. I don’t use it.

tried to wrestle these indicators for long time. After scanning internet for many months I could not find any phisical evidence of backtesting results.
