Hi, guys,

I am developing a trading robot to do trading on exchange. However, I don't know whether Coinbase or Bitstamp is better.

My current findings are:
1) Coinbase needs to charge a lot money per transaction. (about 6 - 7 USD per BTC) Can someone help me verify this for me? And what is the transaction fee for bitstamp?

2) Coinbase do not provide the API to the orderbook details. But bitstamp does.


Thanks.
