It may well be so, but the article doesn't prove it. No sources are given but I'm assuming the graphs are actual data taken from the rule 606 reports. All the data shows is that robinhood makes more money on nonmarketable orders than on marketable ones. The obvious explanation for this is that...

$200 a day on $100K is 0.2% not 0.002% 0.002% is 0.2bps, not 2bps ... can elite traders do basic math?

Legally responsible -- I don't think so. If they had not fixed the issue you might have a case. As it happened, you had plenty of time to re-submit the order before the close. Alternatives to IB -- yes, but the question should be, is there an alternative with a better uptime track record? IB's...

Being on a call lets them use "sales tactics" on you. It also allows them to charge different prices to different clients.

On top of all that, IB's system status page was all green for the entire approximately 3 hours this issue was ongoing.

Same. I was on hold for over 2 hours trying to get some answers about this, but it seems to have been fixed now (at least as of 14:44 EST). I was going to stay on the line to ask what the issue was but I gave up.

Peter Brand -- not to be confused with Peter Brandt.

The first thing to understand about trading is that no one is going to tell you how to trade. It's literally the trade secret. And if you ever figure it out, you won't want to tell anyone else either. Finding a mentor who is profitable is the ultimate shortcut, but impossible for most. I...

This matches with my anecdotal experience. I have a system that holds 100+ stocks overnight and most of the big surprises have come in the morning (since 2014)

From experience, the quandl and yahoo data sources that you mentioned do not always take the primary auctions as their open and close prices. Even if paper trading is part of the issue here, you would still see occasional slippage in real trading.

I suggest that you are looking at this problem backwards. Don't look for a different order type to achieve the closing price, look for a different data source that gives you the MOC price. Do your backtesting with the MOC price and use MOC orders, this is zero slippage by definition.

It's a good point, but technically this benefit doesn't have anything to do with REST itself. It comes purely from the fact that REST is built on top of HTTPS, and most languages have a client built in. If your language doesn't (e.g. C++), you still need an external library. Some aspects of...

I'm thinking about using other ways of getting to work, like using an electric vehicle like tesla or volt. Anyone have any experience driving to work in a red painted car? I hear more and more people are using red cars for their drive to work. Can you do 0-60 in under 10 seconds in a red car?

I don't get it. What is the point of asking this question? Why would you want to use a REST api for trading? Whether it is possible to submit 200 orders in one minute depends on your broker, and has nothing to do with REST.

I would definitely think twice about opening an account with AMP after reading this story. Transparency is key. Thanks for posting

Penny stocks? Very few stocks trading 300 million shares a day. What kind of holding period do you have on this strategy?

I'm curious how it works doing such large orders. If you put in a 10,000 share limit order, don't you get completely wrecked by adverse selection? People leaning on your order, etc. I thought supplying liquidity like that doesn't work in today's markets. Does the lightspeed per-trade rate only...

Def, I appreciate that you took the time to type out such a long reply. (Although I am not buying the SEKH example, obviously such costs need to be passthrough) I agree IB's systems scale fairly well to a high number of users. The fact that IB operated as-usual through the crisis while some...

Buying direct from exchanges can be a good choice as 3rd party data is often flawed in numerous ways. Go to their websites and look for historical data. You will be looking at several thousands or even tens of thousands of dollars per year for this data. It is gigantic in size (gigabytes per...

The observable fact is that IB is not interested in serving clients who want to direct route. There is a class of strategies that require it, and because of these fees they simply cannot be traded at IB. So those traders go elsewhere. The reasoning for IB to leave part of a market that could be...
