KymarFye; I guess you know by now taht was a very good post on your part. I want to add something that may not be directly related but has to do with the Voodoo in TA. I haven't seen anyone else mention this but TA that depends on volume such as OBV is bound to produce an error in it's basic calculations if used as is across a split period without manually adjusting the trading volume data. Now most TA uses Price and Volume in one form or another, & what I've found is the data we get to plug into the charting program we use ; has the price adjusted for "splits" but not the volume I haven't yet found any of the data sources I use adjusting the volume for splits nor do I know of any canned charting programs used over the web that adjust for the pre/post split volume.
