"My system is so good that it's going to break the bank?" Oh c'mon! *laughs heartily* I'm sure refco, cms and fxcm are shaking in their 20 billion dollar collective shoes! Hahahhaaha! You really think you can break the market makers with your system? Well, Pete, I've got to admit, you've lost a little credebility by saying this. I want some of what you're smoking!

I was just talking with George Soros the other day and he said he's planning on shutting down refco the day you release your system. He said he's afraid you and your gaggle of customers are going to take him to the cleaners and he'll be broke by the end of February! *chuckles*
Automated trading systems can be a nightmare as the API's are constantly being updated and changed. Just ask andrew from fabrefactum. I would say keep it manual. It will serve you and your customers better in the long run, I believe. But hey, with your system, we'll all be retired by march!
Thanks for the good ol' belly laugh.
