Actually anyone *could* have a signature back in the day. And you're right it was getting abused left and right and was becoming an eyesore. Maybe Baron remembers...

I don't think this particular scheme was counting on a loss in one account and a gain in the other. It sounded like the whole transaction happened almost instantaneously and poof the money was transferred. I'm starting to think the accounts were somehow linked where once the shares were bought...

Jesus no wonder I went into engineering instead of finance.

But to sell it in BVI he had to have owned it first. If he already had N USD to buy the stock originally he would just get his money back after selling it. Did he fly to the BVI with stock certificates in his briefcase?

There was a fairly in-depth article in The New Yorker back in August too: http://www.newyorker.com/magazine/2016/08/29/deutsche-banks-10-billion-scandal The mechanics of how this co-called "mirror trading" moved money from Russian Rubles to USD in another account still eludes me: Vlad wants to...

I've been able to work out logging into various web sites using C++ and libcurl but it took a lot of sleuthing. You have to be able to make sense of the source html and javascript of the web page. Frequently you'll also have to sniff the packet exchanges between your browser and the target web...

That won't work. Your program needs to go through all the login steps that your browser does to gain access. In general this sort of thing can be very complicated and takes a good bit of hacking. Surely eoddata has an API with documentation and code samples.

Something you should consider before using a password manager is using 2FA for your important logins. I've enabled 2FA on every important login to mitigate password loss. These include: Google mail Yahoo mail Interactive Brokers Oanda Purse.io Github Cex.io Coinbase I don't consider forums...

My main laptop is Linux with whole-drive encryption (LUKS) and a long-ass password. That's where my other passwords are.

In my backtester I close the positions FIFO since it's easier to program. It really doesn't matter. e.g. I opened a series of long EURUSD positions and now I start opening a series of shorts to close the longs. I start at the oldest and move forward in time. Mathematically it doesn't matter...

I kinda figured. I know from experience that (for all their faults) gmail at least doesn't sell addresses. For one-off message board sign-ups (other than ET of course) I'll use guerrillamail to avoid this issue.

OP implied that the email address that received the spam was only used to sign up for ET.

Yes that's right! The world's supply of oil isn't finite, it's *infinite*. Wake up people!

Nah. You can reliably trade just the greeks on index option spreads. I don't know/care/speculate about where I think the underlying is going. I just trade the hard right edge.

The IV for the underlying is calculated by mathematically combining the ATM IV of the options. As far as how to do this, it depends. Some combine the ATM IV of options across several expirations. The "combining" algorithm is not standardized.

GPU memory arrangement is not simple and will vary widely among manufacturers, GPU models etc. Yes GPUs have common/global memory but again it depends. It may be so slow that it's not worth accessing in parallel. You'll have to research it and do some of your own prototyping. Choosing CUDA...

GPU programming whether it's CUDA or OpenCL is still something of a black art. The real problem with any kind of parallel programming is finding parallelism opportunities in algorithms. Some algos simply don't lend themselves to parallelism where others are a slam-dunk (like Bitcoin mining)...

So how are you doing this simulation with SL and TP? Are you using a random walk price generator or something simpler?

Have you looked at OCA (One Cancels All) orders? You assign the related orders to an OCA group and if 1 fills the others are canceled immediately.

Ultimately the companies that issue the stock are the ones that hold the record of who owns their stock. Brokers just match buyers and sellers more efficiently. So ultimately the blockchain solution would somehow have to match buyers and sellers with something like the NBBO, limit orders, etc.
