I am not sure but I still think trying to define the trend change and anticipate the trend change can be helpful.I just know trying to call the countertrend day and shorting is not with the rare exception of shorting when we are at or above the upper band for 4 or more days.
One thing I am looking at is going short when the 10 d SMA of the trin reaches .9 and going long when it hits 1.2.BTW we are at .92 now.
Can anyone that knows how to use a spreadsheet( example Warp) run the data?
