Here we go again. Attached is Jack's document, "Catch Up with Tomorrow's Paper Today -- Technical Analysis Used in a Manner to Anticipate the Market"
(SIDE NOTE: Since this is the "prediction thread," funny how this title reeks of prediction while all Grobeans vehemently deny predicting)
In this document, Jack advocates buying the "0 to 7 shift" of the "P,V relation" (see last page). Nowhere in the document does Jack specify which stocks to do this on.
QUESTION: Does buying the "0 to 7 shift" provide an edge?
Trader666 Approach -- Jack listed no qualifiers about which stocks to trade, so the implication is that it applies universally. Therefore, start by testing on portfolios of randomly selected stocks from the set of all listed U.S. stocks. Result: spectacularly bad equity curves. Next, try testing on small, mid and large cap stocks (the stocks of the S&P 600, 400, and 500 indices) to see if performance varies by market cap. It does not and is spectacularly bad for all. Next try several technical filters, one at a time. Result: still more spectacularly bad equity curves. Conclusion: If buying the "0 to 7 shift" of the "P,V relation" does give an edge, it's not enough of an edge to show up in these tests and is not good enough for my trading.
"A Team" Approach -- Add a boatload of ADDITIONAL conditions that were not in Jack's original document and declare that the "P,V relation" works after all.

Which approach more closely tested what Jack originally wrote in "Catch Up with Tomorrow's Paper Today?"
a) Trader666's approach
b) I can't ever admit I'm wrong and besides, Jack is my master so the A Team approach
c) I'm so stupid that I can't even wipe my own butt so the A Team approach
d) I'm a Grobean and to me, white is black and down is up so the A Team approach
e) I'm a Grobean and since everything I say is true (like I make 3X daily range and never have a losing trade) I deem the A Team approach to be more in line with Jack's original paper, therefore it must be

Quote from makosgu:
Mon ami! NONE OF THE ADDITIONAL CONDITIONS that YOU USED were in the original document either! For the Nth time, you can reread the document.
If the author of the original document makes no such mention of using the inputs you used, how is it that what you did was a measure of accuracy???
given that the author of the document did not make any recommendation of what you did...
