Up +18K, so you felt good about yourself and decided to "tweak the system", which led you to a big loss. Ain't that right, neke?

When did he claim he had a 50-50 chance on a trade? Have you considered may be he had a strong reason to take position on those stocks and was proved otherwise?
I understand the risk management needs a lot of work.... but lets not throw too much at him...
Quote from illiquid:
I'll bet the instinct just isn't there; if you're already up on 5, 10k shares, why press your luck, right? There's a natural asymmetry everyone shares. But remember, the market will always give you as large a losing position as your buying power can handle, whereas shares on the winning side are as (relatively) scarce as gold.

Just checked, and I am up 6K since you "begged" me (5/7/2010). That's not bad![]()
Yes, seriously, I am re-evaluating my discretionary trading. It is obvious I cannot continue like this. It appears given enough rope, I am all too eager to hang myself. At the same time I do not think ceasing completely is the answer. I am looking at restrictions I can immediately put in place/enforce for my discretionary trading,

Quote from neke:
This is an example of what I call the "leverage handicap". You are shorting a stock in two trades. The stock goes from 120 to 100 in the first trade,
and then back to 120 in the second trade. You would think that is a break-even trade (minus commissions). But it is not, especially if you go with leverage like I do.
At the first trade, with a balance of say 150K in account and buying power of 300K (2Xaccount), you could short 2500 shares @ 120. You cover at 100, gaining 50K. You now have 200K and a buying power of 400K. You can now short 4000 shares @ 100. You cover at 120, losing 80K. On the whole you have lost 30K (20%) through pure stock volatility. Does not really matter whether the stock goes down first and up or the reverse.

This year it has been close to 50-50 proposition on trades (excluding averaging down), so the negative effect of leverage has become too apparent. Going forward for the remainder of the year, size on stocks is being capped at 1Xacctvalue (currently $210K worth), while for options the value of the underlying should not be more than 3Xacctountvalue ($630K worth) - example maximum permissible SPY calls would be 58 contracts (with SPY @ 108). My position monitor will see to the enforcement of this. So yes, no more size of $778K on JWN with an account size of 213K!
