Now what does ECN stand for!
I am in Australia, a tightly regulated place. I do not have any of the troubles you describe.
I trade on a GFT platform with dial-up internet (46kb/s) and have never had the slightest bit of difficulty.
I do not use Java and have only very recently downloaded it.
The KISS principle applies very well to me.
