API: New Rate Limits

Good news for API users:

In order to further encourage the use of bulk orders and amends, we have made the following change:

  • Bulk orders (POST /api/v1/order/bulk) and amends (PUT /api/v1/order/bulk) are now ratelimited at 1/10 the normal rate. This was previously 1/2.
    • This is rounded up. Inserting up to 10 orders is ratelimited as if it were one request. 15 orders is 2 requests, and so on.

Additionally, we have adjusted our HTTP Keep-Alive timeouts from 30s to 90s, which should help those of you who are aiming for the best possible latency. As always, if latency is a concern, we recommend using AWS eu-west-1.
