Hi Bitcointalk,
I'm Joe from
Magnr, a bitcoin trading and savings platform.
Over the last few weeks we've been working on completing our trading API and are in the final stages of testing. If you are interested in becoming an early beta tester (which will give you early access to our production API) then let us know here or by dropping us a line on our support desk

A little more about our trading platform, over the last three years we've brokered over US $80 million in trades. Formally known as BTC.sx, the platform offers 2, 5 and 10x leverage on Bitstamp, Bitfinex and ItBit.
Our USP (unique selling point) which sets us apart is our model which helps minimise counterparty risk between exchanges. We do this by segregating our client's deposits from our trading funds. When we were integrated in MtGox, this enabled us to honour every satoshi owed to our clients when they went bankrupt.
