Jack Hershey's Methodologies (SCT & PVT)-Good Bad or Ugly

[Fireplace]

Trader666 still doesn't understand what to 'ignore' someone means. He tries, we'll give him a bit of credit. But still failing pretty badly at it.

You're such a chump! Better get back to your 3-ring binders

Why are you so obsessed with 3-ring binders?

It's so nice not to have the cut and paste monkey show up every 5 minutes.

New restrictions ROCK!

It looks like they have contained Sybil.

At long last. Now this thread can be used as the info dbase it was meant to be.

Jack unsuccessfully tried to impose static parameters on stocks in "Tomorrow's Newspaper Today" (attached).

I tested buying Jack's "0 to 7 turn" of the "P,V relation" per page 8 of his paper on 1000 stocks from 2000 to 2005 -- a total of 5000 stock-years -- using spydertrader's code for the scoring and exiting 5 days later and got the equity curve below.

Quote from RCG Trader:

Backtesting has limits. Static parameters imposed on a dynamic system. Its like trying the find the function on a curve that is always changing its slope. Good luck with that.

P.S. Backtesting doesn't have to use static parameters any more than realtime trading does.

Anyone and everyone who trades uses nothing but historical data as the basis for their trading decisions. Even tick charts are history by the time they reach one's screen. So anyone who trades and says that backtesting isn't a valid concept is contradicting themselves.

yup he is history.

I wonder if the 'weirdo's' head has exploded yet from all the pent up rage of not being able to post all his garbage here anymore?

 

[Trader666]

Then how did he just burn Sooky with a PM?

I know, a pm here and there but the tone is very subdued now, gone is the false bravado, the 'you can't block me' attitude.
