I'm looking for a broker that offers a quick responsive trading execution platform at no charge. Does anyone know of any? I know of Think or Swim, but in the past i've had bad luck with them regarding a very slow order execution. I heard of Ninja trader, but i've heard of many connection drops.

So you think to find a broker pushing your orders through for free?
Business always has some basic costs... - hidden or not.

Even if you are going to play lottery only 50% of
the input money is getting back to the clients :-o
Similar for casino et al.

As long you are looking to do serious business in trading
allow some basic costs which should be seen as business costs.
Treat them like this!
