Well, if their system was any good it should have been a simple matter for the defendant to demonstrate that it did add value.
Why this concept escapes the market efficiency discussions here on ET has always confused me. Market efficiency is all about the current price reflecting "all publicly available information," whether known or anticipated. That is it. Nothing more.Quote from harrytrader:
CFTC v. R&W TECHICAL SERVICES, INC.
"Virtually the entire economic community is in agreement, however, that the efficiency of the market is sufficiently strong so that all publicly available information is rapidly disseminated and is then almost instantaneously reflected in the price for any widely traded investment contract."


) Also, saying that the "market is random" is a generalization about how all stock prices react at all times, and in that sense is certainly not true.Quote from esc_trader:
The vast majority of TA is worse than useless, it's misleading. It is effective only to the extent that others are using it too, and their hands are strong enough (ie Big players) that they can hold prices at their desired levels.
