I have Verizon DSL. It seems to fluctuate in and out sometimes, which scares the crap out of me as far as using it for trading. I don't know if I'm being paranoid or not, but it does worry me. Is there a way for me to test my connection? Also, is there some sort of monitoring tool I can install that may warn me of dropped connections or the like? What is all this ping test stuff? What is a good speed in milliseconds for trading remote? Are there any other diagnostic tools out there? Thank you.
