Hi Dargo,
Can you clarify some points regarding the API?
1) What is the request/throttle limit before getting banned, if any? (e.g. 1 request per second)
It's a bit complicated since there are a variety of factors that can change things, but the basic limits are as follows. The limit for sustained requests is 1 request every 5 seconds. The limit for sustained orders is about 1 per minute. The sustained limits can be exceeded in short bursts. Keep in mind that this is subject to change as we see how people use the API.
Please increase the rate limits. One request per 5 seconds is pretty low but I can work around it. One request per second would be more resonable.
However one order per minute is very low. Overall I place less than 60 orders per hour, but sometimes I may need to place 4 or 5 orders in a minute. I run into the rate limit too often.
