As a Mac user, I am very happy with AMP+Rithmic+MotiveWave (or Sierra Chart on PC) setup. TWS is user interface nightmare.....
Then you need a new and more reliable method of communication with AMP... If you do not know what this is, I can provide more recent pics and descriptions of that thing.
I have one of those. But all is well. I can even fund the USA account from the UK using SEPA. We are talking in a timely manner and I do not need that bakelite thingy in your picture.
They dont have a website. You get an invitation to join them, once you reach a certain monthly volume threshold with a certain broker. It is a pretty exclusive and secret thing, thats why you dont find much about it here on this forum.
