cy you wrote FWIW - If Larry's Hal system works on a 6 month scale as his chart indicates, it could be scaled to work on much smaller, quicker intervals and used for day trading if the data inputs are available on intraday intervals.
answer: (1)Hal(non public) does trade like Zeev's trades and I agree the likely gains are much smaller then Hal(Public) likely gains. (2)My "problem" has been trying to take Hal(non public) day trading system and bring it up to Hal(public) longer term trading system. (3)In fact the Hal(public) may be replaced with $BPCOMPQ SYSTEM in the near future.
Hal(non public) can estimate about 90% Zeev's buying of the Q before Zeev's posts it. Zeev uses "the box" and a reversal on either one minute of 5 minute chart.IMHO.
Hal(non public) is very poor about estimating Zeev's sell of the Q. Zeev uses a key stock to sell the Q and it keeps on changing over time.IMHO.
Another note Mr. sylvester80 is the one trading QQQ and I have not figured out his system. After checking with Esignal Time and Sales in real time, sylvester80 does real trades.IMHO
