GDAX is that you?

...that being said. very nice work - i was only joking! :) i really want to get into svg stuff. have for awhile. i feel it would take my frontend game to the next level.

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

Nice work! I love the layout. I'm curious if you have any plan to monetize in the future? - Or if there is a common way you could monetize a site like this?

Thanks!

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

Hey love the charts, it does look like cryptowatch (which is a complement), i havn't looked at traderwatch much but it is paid and lots of noise there with people creating arbitrary breakdowns with lots of lines on them... but with no solid projection of future movement.

I'm also in the charting/bitcoin graphs business :D checkout https://bitbank.nz we managed to distinguish ourselves by providing live machine learning forecasts combined with granular data that lets you see the price action/movement easily and just focusing on keeping it simple and not adding too many crazy indicators and arbitrary lines. i like this product in much the same way, very clean and nice color scheme.

We use a google app engine/firebase/plotly so we look a bit different to the traditional style, i notice your using a websocket, so your aggregating data on your backend? we are also doing that which gets a bit expensive (and we crunch though a few million previous examples over loads of altcoin markets every few seconds to make predictions). I wonder if there's a way to deffer some operations straight through to the exchanges / data providers?

Let me know if youd be interested in adding some of our forecasts to your graphs, We have a live data feed API for our forecasts you can subscribe too. ill give you the product for free if you let me know your from ohmycoin/HN :) we also have an affiliate program so if you link back to us you can make .003btc every paying user referred :)

Thanks, awesome work! :)

Kind Regards, Lee - founder https://bitbank.nz

Do you store the tick data in a database? if so what database do you use? And also, is it a matter of using the API from the exchange and displaying it in your format? Thanks

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 node for the moment.

It's kind of that, although the client doesn't talk to the exchange directly, it only talks to the backend. The backend consumes events from the different exchanges, transforms it to a common format, stores it and serves it to the client (in brief terms).

This must be costing you a lot. Do you have plans to monetize? Great work!

How would this be costing a lot? Through server costs? They wouldn't be too expensive would they?

I figured it’s a lot of data to pull from all those exchanges and pump to a client.
