  3. GBP traded thru my no touch, out the premium. Earned a bit on the short spot hedge. Out ($250) per unit, net.

  4. Purchased the CME 280/300/320 call fly for $5.50 today. A bit OT, but figured I'd post the play. Vols haven't come in as hard as I assumed they would.

    Heard from my broker that the bank is making a market in DAX exotics. Touch/no touch, caps, knocks... Will price some today and possibly trade some in the morning. Dax vols have been very quiet, not ideal for selling gamma.

  5. DAX double:

    Traded the 7d 4900/4750 double barrier[range]. Entire premium paid is lost if either strike is hit. This differs from a conventional double-knockout in which the opposing strike would remain "live" if one were hit. A fixed payout of $150k EUR is paid if neither k/o barrier is reached. Position risk and payment for the position is $50k EUR. I've been using various models to price; finite difference, Laplace transforms, among others.

    Dax double barrier[binary k/o range] -- 4900/4750 K/Os
    Premium: $50,000 EUR
    Payout: $150,000 EUR [includes prem paid]
    Expires: Aug 3, 2005
    Negative edge: $9,000 EUR

    A short strangle would be the analogous position in the vanilla-options. Obviously there are significant differences. There are no binary conditions with a vanilla straddle, yet risk is unlimited on the call[vanilla].

    Defined: Short gamma/vega binary-strangle with a debit haircut. I own a piece of this trans, brother's fund is the holder.

    Interesting, in your assessment, what are the odds os success?

  7. I neglected to mention that the position is neutral at 4825 basis Dax-cash. Odds are 5:2 against based upon where we're trading, IMO

    Thanks, so is that a positive expectancy of 10k? (100*.4)+(50*.6)

  9. yes, but as edge bleeds into the position the expectation increases quite a bit

  10. Paid 39.50 on 20 ES to hedge the barrier.
