You both trade differently. Size, risk, and opportunity stands to be the margin. Big time pair trades will at somepoint blow you out. I've had best friends clear 7 figures that ended up working back at some chop house as a clerk or brokering, scraping by barely surviving. Not to say it will happen to you but it will eventually, hope you work in a single story building or have ample medication for the inevitable. It will work till it doesn't, and risk in my opinion is totally out of control. The real money was pair trading internet techs in the boom, the sunburnt limey was a pair trader that went home to Europe broke too. Good luck, hope you can make go, what I couldn't. I'm rambling now.
