    Options assignment lotteries

    This was the regular January monthly expiration. I don't have the historical open interest offhand, but the current Feb's have about 5-6k contracts open. I had a tiny % overall but enough contracts to think that full assignment might be unusual in a situation where the stock was not ITM. Yes...

    Options assignment lotteries

    i recent sold some calls that expired exactly at the money and ended up getting fully assigned on them, which I am told is unusual when there is no news or after hours move in the underlying stock. I wanted to know if this was just bad luck, or if many of those contracts were voluntarily...

    Greenwich Mansions Get Biggest Discounts -- mentions the Peterffy estate

    Well, at least Peterffy's IBKR stock doubled so I guess he can afford to take a $43M loss on his real estate sale. He's still making a good trade, ditching CT and their badly managed government and income taxes for tax friendly FL...

    401k for short-duration trading account (tax benefits)?

    You have the right idea/intuition, but not quite the right math (or good enough returns to make the idea work out financially, although it could). As others pointed out, for a pretax IRA/401k, you pay ordinary income tax plus penalty if young on all withdrawals. There is no concept of capital...

    Interactive Brokers customer support totally broken

    Easy money buying in the after hours if you listened to the earnings call. The new tax law is going to be quite good for IBKR.

    Cboe approval shakes up stock market’s closing auction

    But I wonder how they will charge less than the primary exchange that way. Or I guess maybe CBOE just loses money on days where their own auction is imbalanced and they eat the loss to send it to the higher priced primary exchange? Either way, it's good to see some price competition.

    IB third party wire transfers

    IB has allowed third party wires, in principle, for some time. However, they are a big pain and require lots of documentation to justify the wire, the relationship with the third party, etc. and after providing that, they might or might not allow it. Given the way scammers could abuse this...

    Warning signs before MF Global went under

    I don't remember which, but over the years various futures firms have gone bust (RefCo, MF Global, etc). If you were paying attention to the rumors on the Street, people knew it was coming towards the end. I heard about hedge funds frantically trying to wire they cash out or bring their...

    Interactive Brokers - chain Orders in a row

    I think you may have to wait until the first order fills, at least in part, before you can attach the 2nd bracket order to the first bracket order.

    Is it possible to customize order routing in IB's mobile app?

    I don't think so, but it's been a while since I traded via the mobile app instead of TWS.

    IEX versus Interactive Brokers SMART routing

    IEX is great at PR but not some magic exchange where everyone gets filled for free and with price improvement. Often other exchanges are better outright, or other's are better factoring in fees/rebates, or better fills on dark pools, or any number of things. Smaller orders will often benefit...

    Box spread "substantially identical"?

    My understanding is that different strikes / maturities of options are not substantially identical to each other. however, if you trade the $20 leg at a loss and later rebuy it, that could trigger a wash sale. So since you don't seem to have any of the same strikes, I don't think you'd get a...

    IB warrant info

    Worth checking the deliverable not just the strike on those (assuming you meant the ticker I think rather than the one you wrote, which doesn't come up). Not long.

    SEC alleges ex-Florida firm defrauded thousands

    Is it just me, or is Boca Raton home to a lot of this kind of sleaze?

    Why cant IB allow shorting of BTC futures with a margin requirement of 500-1000%?

    They do this for volatile stocks. Some are 100% long but 200-500% requirement to short. What they really need for bitcoin futures is a 24x7 market. Then at least if it's liquid, the brokers can blow you of your short fast enough they don't lose money and they can offer leverage on the short...

    Customers of Interactive Brokers file class action complaint over management of portfolio margin acc

    I have some sympathy for people hurt by margin requirement changes, although of course they agreed to this in the margin terms. I think margin requirement increases, especially during times of high volatility, is an under-appreciated risk factor for those trading on margin. I worry about this...

    Customers of Interactive Brokers file class action complaint over management of portfolio margin acc

    That NY Post story seems to have boiled down to this: "guy takes giant VIX futures position, sees an expiration date on IBs website that's 1 day sooner than the real expiration, does nothing hoping they will settle on the day he thinks, and loses a boatload when the market moves against him on...

    Peterffy (IB) takes out ad in WSJ to warn against BTC futures

    IB slapped a 500% short requirement on DRYS, a highly volatile shipping stock, in the wake of their 20x runup a year ago. BTC looks at least, if not more volatile, to me so it wouldn't surprise me given Peterffy's anti-BTC stance that they could have some really high short requirement on...
