Has anyone else experienced a falling off in quality recently?

With Squaregain I am finding that numerous attempts to trade, within the indicated sizes, are failing to go through. You just get a silly message saying " ........wait a few minutes for the trade to go through..." but it never does.

Are there any on-line brokers that, in users opinions, are more reliable in this respect?

Any more opinions please?

foale (still there??) - how do you feel now about Barclays V etrade ??? Any changes to report or do you still prefer etrade??
