In the previous post I mentioned how I hate arbitrary technical analysis (TA). I forgot to mention the methods of Tom DeMark and how much I appreciate his efforts to take that "arbitrary factor" out of TA.
The technique that Mr. DeMark is most known for is his TD Sequential setup and countdown. The indicator doesn't always work but I was amazed by how much it matched up with Tom O'Brien's method. The above chart is that of AEM and gives a buy signal one day after Tom O'Brien picked the bottom.
