Any active BTC traders?

Curious to hear how many active traders are on this board and which exchange(s) you trade with and how many trades per day or week you make? What trading platforms do you use, ie exchange website, 3rd party app, mobile app, etc. and what, in your opinion is currently missing from this space that would help you with the process of analyzing market data as well as placing your trades.

I'm a software developer who has been writing stock/futures trading related software for trading my own account for the last 8 years, and I would like to see tools for Bitcoin trading that provide similar features to those found in the stock and commodity markets in an effort to help increase liquidity on the exchanges, in turn helping bring down the transaction costs for consumers and merchants who rely on these exchanges to convert their funds to/from BTC as a course of their business.

Looking forward to hearing your replies.
