<DIV><FONT color=#000000><FONT size=3></FONT></FONT><FONT size=3>I enjoyed 
reading some of your insightful posts about trading systems.&nbsp; I though, 
maybe it would be worthwhile to discuss whether a system ( either mechanical or 
discretionary) is necessary for a successful trading.&nbsp; Do we need to&nbsp; 
have a system as a decision support in our decision making process for 
trading?&nbsp; If yes, do we follow&nbsp; our own self-made system or a 
carefully selected one?&nbsp; If not, then what are some of the individual 
characteristics ( such as experience, commitment and discipline) and/or 
contextual factors ( such as time pressure, outcome feedback, and incentive 
schemes) that may influence our reliance to a trading system?&nbsp; And how 
these aforementioned factors may reduce ( or increase) our trading performance 
and accuracy?</FONT></DIV>

    and CTA's {02}<BR><BR></DIV></FONT>Hi Gary; <BR><BR>Its easy, say you invest 
    100K with a CTA, at the end of the year after all fees your account is worth 
    $150K, your account increased 50%. The reason this is so good is the amount 
    of money that he actually used to create that $50K increase. Most good CTA's 
    will use on average about 20% of available equity for margin money 
    (margin/equity ratio), the balance goes into T-Bills.<BR><BR>So, if you 
    invested $100K, our hypothetical CTA would use $20K to trade with, place the 
    other $80K in T-Bills, and proceed to create a net profit of $50K. This is a 
    actual return of 250%. The trick question is ascertaining the margin/equity 
    ratio. Most CTA's in their disclosure documentation specify that they will 
    not exceed a 50% ratio. Assuming the worst ratio possible this still 
    translates to a 100% return.<BR><BR>The secret to successful trading is 
    managing your risk exposure, everything else is secondary.<BR><BR>Best

    <BLOCKQUOTE>John, thanks for the very enlightening posts.<BR><BR>I have 
        a really basic question: how is a CTA's return calculated? I see all 
        these CTA's reporting 10%, 50%, maybe even 100% in a year, and that 
        doesn't seem all that astounding to me. Certainly my system is returning 
        a lot more than that, and has for over a year. (Too bad I haven't been 
        able to trade it with real funds until recently. :-( ) But I wonder if 
        maybe they're reporting it differently than I am.<BR><BR>Does a CTA's 
        return assume zero leverage? I.e. is a $100k return on an account 
        trading the S&amp;P considered 100k/(1400*250) = 28.6%? What if the 
        system has low drawdowns, allowing high leverage, and the account 
        started the year with $50k? Is that still an (unleveraged) 28.6%, or is 
        it 200%?<BR><BR>I'm just puzzled why people get excited about a 50% 
        return, when I would have done *way* more than that if I had been able 
        to trade my system for the past year. I'm certainly no market wizard. Am 
        I comparing apples to 
    oranges?<BR><BR>Gary<BR><BR><BR><BR><BR><BR></BLOCKQUOTE>&lt;&lt;&lt;&lt;<BR><BR><BR><BR>.o&copy;&ordm;&deg;&uml;&uml;&deg;&ordm;&copy;[<?color><?param 0000,8080,8080>

Not widely known but you can download upgrade to Q98, which is Y2K
compatible, for free from Intuit web page. Looks like you started this year
