For MC, I am quite happy so far but really hate their DRM. It connects to some outside machines quite often - so you have to trust them that they don't channel your self-written code through that and run it themselves. Couldn't they just send people a custom SSH key that unlocks the app? Anyway... .

My suggestion to all traders in 3 steps:
1. Turn off internet connection
2. Load your favorite backtesting or TA program
3. If it fails to load or execute because it cannot connect to the internet uninstall it and never use it again
Simple, 1, 2,3 ...done

Of course they can send a custom SSH, Tradestation did it before, first with a dongle and later (TS2000i) even without a dongle. But they want to see in your PC. And therefore they need internet access. If your own programs are interesting they will copy them. I asked MC to sell me a version without the internet connection, but they refused.
Maybe it would be interesting to publish a list here with "safe" software.
