Trading off the floor

I have traded futures (most financials) off the floor twice in the past. To be honest, with no success. It's been 6 years since I've attempted off the floor trading. Some of the problems I encountered were bad fills and dead time between making a buying or selling decision, calling my order in, and the actual execution of the order. I'm wondering if anyone can tell me if things have changed in the last 6 years. I would think with the advancements of computers, the Internet, etc. there is now less of an advantage to being on the floor itself.


Does anyone here successfully trade off the floor? Back then, I think it was almost impossible to overcome the disadvantages of being off the floor. I'd love to hear comments from anyone successfully doing this. Thanks.
