That education, for a child or an adult, is primarily what one gains from a Also, one need not trade a small account intraday. I make small trades, but they are always with a multi-year perspective. Give me limit orders and small commissions, and I am happy. (N.B. I use a different broker/don't have a first-hand perspective on Robinhood.)

Unrelated but usually you should place a market order usually, not limit. Limit orders take longer to fill, your idea of limits is probably wrong and will lose money compared to a fair market match, it's not worth taking the risk that your order won't be filled, etc.

There was a discussion last night about this. Some of the more technically competent posters dismissed it because it's unbelievable that a financial platform would roll their own date-time implementation.

That means people should reevaluate the weight of the opinions of those technically competent posters - we have a screen shot that robinhood did roll their own implementation because yesterday was March 2nd and its app was requesting March 3rd. That at least means that some portion of their stack used roll your own datetime library. That would not actually be a problem as long as the entire stack got the same library…

I'm a QA engineer and this is freaking infuriating. I just went on Linkedin and 0 QA engineers. Just some QA associates that have no tech backgrounds. And one QA Engineer opening. I wonder how long it's been open? How does a trading platform not have a big team of QA engineers? Some dev managers, devs are so freaking arrogant. They think since they aren't coding, they aren't smart and they aren't important. This isn'…

As someone who also needs to explain the importance and nuance of QA engineering to my startup partners, do you have any go-to resources you use to describe/sell the position? Genuinely want to expand my ability to speak to the role.

That particular API endpoint is just returning market open times, in which a request for tomorrow might be perfectly reasonable. https://api.robinhood.com/markets/XASE/hours/2020-03-03/ vs https://api.robinhood.com/markets/XASE/hours/2020-03-07/ This whole discussion lacks context to the nature of the requests, aka a front end code review.

  if (max_drift_delta > delta(order_live_date,system_live_date) {
    # oh crap, something is completely broken in our system where did this come from?
    blow_up("terrible things are happening! how did we get this order")
  }
