    Trading Rules

    On a day like today (SPX down 50pts, -1.7%, VOL popping from 14-ish at Friday close, to breach 20.00), it's important to note that the "rules" posted in the OP lack any specifics for position/risk/money management. They are long on entries, and way short on exits. It's pretty typical, but still...

    Attention day traders

    "And now, ACT THREE!" SPX down 1.53% at 11:55ET, with the DAX cash closed at -2.46%, give the SPX an excuse to rise a bit: 7pts or so. {{ 2.5%/2 = ~1.25%| so we're down an extra 7pts, which is not *huge*, but again, there is an "excuse."}} Since we enter Euro-close just as US starts going to...

    Apply for CME/CBOT Membership to lower fee for Individual trader questions

    You'll also be tagged for data. Depending on what you trade, perhaps insignificant. If you're trading CBOT, though, some of it can get pricey.

    VXST missing or not?!?

    MYSTERY OVER! ("And the bells rang, and the children all sang, and the old men in the gutters all mutter, 'Dang.'") IB has now posted a new entity, called VIX9D -- new meaning, that if you had any statistical or DB attachment to your old VXST/fields, you will have to hand-craft an attachment to...

    IB - buy and immediately sell stocks - best way to do it?

    I think what you want is to create a bracket order in BookTrader, with your limit bid set +1¢ above the BID, and your limit ask set -1¢ below the ASK. For your brackets, you can set your profit-taker 0.005% (half-a-percent) away, and for your stop loss 0.0025% (quarter-percent) away. Set the...

    credit spreads.. the good, bad, ugly and dirty of them?

    Option contracts operate under multipliers like 50; 100; 250; 1,000; 10,000. (I'd love to know if there are others, but it's not going to be something I will ever commit to memory, either.) These multipliers happen to coincide with equity shares covered, for equity options. (i.e., 1 contract ≡...

    how to lock profits

    If you wished to lock in that profit, you could do as smallfil posted, and sell-to-exit. At that point, should the underlying fall, you have 100% of your current profit. Should the underlying continue to climb, you don't participate. Put slightly differently, if you owned the 340, you could sell...

    Dispersion Trading

    No, you don't. It's zero-sum math. When you sell a cash-secured put, your required margin capital will grow by [(Stock*100) - Premium]. Your premium has already been used.

    Why are Central Banks using Economic Growth Control Mechanisms to Control Inflation?

    It can't *directly* affect unemployment -- it falls under the oft-used aphorism of "pushing on a rope." That doesn't mean that Congress (in all it's 'wisdom') doesn't want the Federal Reserve to *try*. But 50 years ago, in a fit of Wanting To Do Something, it ended up in the Fed's enacting...

    VXST missing or not?!?

    Indeed! It's now the VIX9D! No announcement (throughout the CBOE website, which is grotesquely out-of-date). And for sure: IB remains in the dark on it. As well: Yahoo.Finance. And obviously, someone clued BarChart.com... Nothing anywhere on the web -- this discussion right here might be the...

    Will MMT Economists Finally Get Their Day in the Sun?

    Just to add grist here, let's go to Robert Barro (and his friends Milty, Gary, Merty, Jerry, et.al.) https://www.journals.uchicago.edu/doi/10.1086/260266 The first line of the summary reads, "The assumption that government bonds are perceived as net wealth by the private sector is crucial in...

    That's two conclusions fucked up in two posts. You must have a lot of friends.

    XLU

    Just to be all sciency, "XLU is up today; my notion worked out." or "XLU is up today; my hypothesis failed to be rejected on this trial." or "XLU is up today; reality comported with my theory this time around." :( (Hooo lawdy lawdy lawdy. This is probably why I'm single. I know.) :D

    VXST missing or not?!?

    IB's TWS has not shown the VXST since Monday open. A chat with IB, and they did not know of it. They attempted on a bunch of machines, and no luck, so they thought it was a 'bigger issue' and would look into it. I looked around a little bit yesterday afternoon, and saw that Yahoo.finance had...

    Heyyyy! Time for Round Two! At 10pm, S&P is down by -0.89% -- expect the DAX to follow suit then, in catching up: down -1.80% tomorrow...

    How to calculate implied volatility for a delta 25 option? :)

    If you're nervous of the math, stop fiddling with "delta=" and find yourself some expositions on IV or volatility or even sigma, and then plug in your 25-delta as a given. MUCH easier.

    Daily Habits - Strategy Improvement

    I am a little bit different, in that I am 95% a net seller to the market -- in vertical spreads on the SPX. Because of that, I don't want to know so much as *direction* as I do *range*. (Which is to say, "Gimme a window. I'll write positions on either side of that [above and below the market]...
