Lorenzo,
thank you. I know that TA + Sierra is great and not expensive, but I have received an offer from PFG. Very competitive. They offered me 0,35 cents less on commission. And for $49,95 their Best Direct Pro Trader which looks pretty cool. I love sierra but Pro Trader is better imho. And offers trading off the chart and manage multi position visually. I can have a Ninja for $50 + additionally $0,5 on RT.
I'm worried about reliability and data feed. TransAct is rock solid but what PFG? If the quality is the same so they have much better offer.
