    Just got a $21,508.58 margin call (DAY EQUITY CALL)

    Well that sucks but that is my fault. My bad. Shit. "John cancel your college plans this semester. Dad just got a margin call even though I wasn't using it." Getting punished for helping to provide some liquidity in the markets. Sigh.

    Just got a $21,508.58 margin call (DAY EQUITY CALL)

    I have a smaller balance with Ameritrade and even though Thinkorswim said I was in the clear to make one more same day trade, I somehow got flagged with day-trading while under a $25,000 balance (for this particular broker). I didn't realize that day-trading an option would trigger this, but I...

    Trump may rattle the markets tomorrow

    There's a lot of inside talk about Tillerson resigning or getting fired tomorrow. Trump has made some ominous comments at a military meeting saying, "This is the calm before the storm." Tillerson, Mattis and Mnuchin had previously made a suicide pact if any of them got removed by Trump. The...

    Programming interviews

    That's a fair question and I agree with you. Unfortunately, sometimes the people tasked with hiring others doesn't always know the full details of what the company wants. At one point in my career, I was asked to interview candidates for a new position opening up and I didn't get much info on...

    One of my favorite scenes from the movie "Margin Call"

    The part where Kevin Spacey goes, ".....what?" is just golden. This is a really good movie!

    What is the main difference between the Mini-Nikkei 225 and the Nikkei 225 (Osaka) ?

    Programming interviews

    The purpose of brain teaser type questions when I give them to candidates isn't really to see if they get the right answer but more so how they go about it and how they approach problems. A lot of these brain teasers aren't really the types to be quickly solved (unless the person has heard of...

    Senseless killing in las vegas. What lessons to draw?

    For me, I'm just a bit dumb-founded about the entire thing because there is so much about the shooting that doesn't make any sense. You have a 64 year old guy who is wealthy with no criminal / medical background who was actively stockpiling rifles and ammo and then systematically planned out...

    What is the craziest mistake you've ever made trading?

    That is an amazing story! Thanks for sharing. I'm glad you were able to turn that snafu around to your advantage. Bob -- quick question for you (I love your posts, btw): Do you remember the May 6, 2010 flash-crash? Do you have any stories about that day?

    Option Routing (Market Makers)

    Quick question -- Are bids / asks FIFO? They're supposed to be FIFO, right? I've seen situations in the past where I felt my order wasn't FIFO and it was upsetting, but I've always been under the assumption that if there is nothing sitting at hypothetical .35 bid and I'm the first order there...

    Searching for helping hands on machine learning project

    I'm always interested and I have a lot of programming knowledge -- but if its on git, are we talking about a private repo? The last thing you want happening is designing a good system only to have it get stolen from someone who has the money and connections to run it on a network far better...

    Tensorflow / Machine Learning and Trading

    GoLang is awesome! When you say it took 10 seconds to run, how much data was it analyzing in total?

    Programming interviews

    The truth is that finding a "good" programmer is REALLY hard. A good programmer to me is someone who: 1) Is willing to follow established company guidelines on source control and code structure even if it doesn't agree with what they've done in the past (although I'm happy to discuss changing...

    Worst case scenario here is that the egg actually breaks on the 100th floor and this method would have taken ~ 49 attempts. The optimum solution to this puzzle is around 30 less than that. (But I see where you're coming from and it's a good start!)

    Python/Pandas Time Series problem

    This is how I store all of my data inside Postgres -- I just use epoch time and then when I use the data, I convert into whatever timezone I am interested in. Epoch time is naturally UTC so it works wonderfully. I've fucked up too many times when trying to store time in one specific timezone...

    Did Trump screw over Puerto Rico with his bond comments?

    I'll be honest and put this out for everyone -- I do not like Trump. I think he's an idiot. The thing is, he's also the POTUS and what he says can carry huge implications. Unfortunately, I don't think he realizes to what extent his words can rattle markets, etc.

    How simple are professional trader's strategies?

    You know what I've found to be really similar? Gaming vs. trading. I love to game online and play FPS. I noticed that when I played a lot and our team lost, I would get pretty pissed off at myself and others on my team. I would call out another player for doing something stupid. I would...
