    Because the return on a bond is not just based on the expected risk, but also on the time value of money (generally we prefer consumption now rather than in the future).

    It could be that it reduces mortality, but it's still above average.

    Nice charts! Which technologies (frontend and backend) have you used?

    The width of the order book panel should always be the same. Which browser/OS are you using?

    BTC-EUR on GDAX is quite liquid, almost always I look spread is 0.01€ and there are trades every few seconds

    I can store the tick data, although I'm not storing it at the moment (I disabled it for the launch and will test the load that enabling it represents). I use Cassandra with just 1 …

    Thanks! I may in the future, but if I do it will not be charging for basic functions or inserting obstrusive advertising.

    No problem. I've certainly taken some ideas from GDAX dashboard, but from some other sites too!

    Thanks. Not at the moment, sorry. It's something that I have on the back of my mind but I haven't made a decision yet.

    It costs me time, basically (which is not to be disregarded). Hosting is cheap these days. I'm using a Hetzner machine at about 30€/month which is handling load quite well.

    Thanks! There are different markets available, indicated by the white dropdown at the top. Currently supporting GDAX and Gemini, but many more coming soon!

    Which one would you use, the CSS "pointer" one? I want to make clear that the user can write in there in order to filter entries.

    Are you looking at the same market? The default market on OhMyCoin is Gemini which has fewer updates than GDAX. GDAX does the fade-in and fade-out animation on the order book, whic…

    Thanks. I've certainly spent some efforts on the client optimization, as some markets produce lots of events per second. BTC-USD and BTC-EUR on GDAX, for example, are often over 10…

    It's ok, differentiation is something that I must look into - and I am. But I first needed a foundation that, is true, does not differentiate it too much yet from alternatives.

    If you mean responsive as in design-when-used-from-a-mobile-phone, you are right. I haven't spent too much time on it yet, but I will.

    The frontend is built with ScalaJs and React (using https://github.com/japgolly/scalajs-react ). The backend is built with Scala too, mostly using Akka Streams for the data handlin…
