Capital One 360 offers P2P payments, which is what BitFloor was using. CampBX supported this as of a couple weeks ago but it looks like they may have removed the option since then.

I'm writing one now, using moving average crossover as an indicator. Going to be using BTC-e if I can get a few issues with it worked out. Been testing it against historic data and it's had good results, but I have some more testing to do before putting money into it.

Nice to see people working on BTC with C#

I'd love to see BlockChain add support for LTC.

The documentation is bare. It's enough to use the API, but it doesn't tell you what the various codes and statuses mean. Also lacks info on how the overall process works, like after you place a trade then what? How do you know when your trade is complete?

There are a number of 3rd party wrappers around the API in the popular languages, but again you have to know how the exchanges function to do anything useful with them.

I'd gladly give a BC tip to someone who put together a useful guide to using the APIs in practice.

Right before Bitfloor tanked I opened up a 360 account for funding my account. What other exchanges also support deposits via 360?
