@jslade kraken is terrible, but amusingly so. at least until the latest "upgrade" (and it took them like 48 hours of downtime). for a few months last year i was running some market-making bots and doing some light x-exchange arb and printing a decent bit of $ ... but it was a great experience in building resilient systems, as literally nothing could be relied on. for example: api timeout & no ack on new order? try again. oops now you have two orders! cancel... times out. am i getting filled... who knows?!

Thanks for confirming. This might be too specific an ask but what rate are you polling the Kraken order book/recent trades at? Do you also have to go through Cloudflare?

@mrdivorce: Yes; We are polling as fast as possible; our edge here coming from fact that we are doing that from multiple servers and localizations simultaneously and constantly expanding infrastructure with the growth of our customer base effectively increasing amount of updates for the exchanges with providing only REST API - and we are planning even further improvements in this part of project in this quarter (Q1/2018)

Just sent you a pm, I was hoping there was an easy way to pull history with matlab (or R) without having to write custom code.

How much history can I pull for low frequency data (like best bidask) hourly or daily?

It looks like a great idea, if it works as promised it will be a success.
