Hi CO,

Interesting thought !!

I'll have to think about it. I can do the math/programming stuff but you likely have a better handle on the markets than I.

I pretty much have always viewed a margin increase as an exchange expectation of increased volatility and if I have made a trading adjustment based margins, maybe I am a bit quicker on the trigger to get out if I enter a trade and it starts to go against me.

Otherwise, I also had the thought that increasing margins might be an exchange expectation of increasing prices as things do seem to be somewhat "percentage based" and 10 percent of 2000 carries a lot more risk than 10 percent of 200 dollars.

I don't have all of the numbers but Ng margins are about half of what they were in 2009 with price down where it is and not much in the way of volatility. Will be interesting to see what happens here as we go into winter if price action starts to pick up a bit !!!

Have to give your comments more thought, or add to them if additional thoughts come to mind.

Thanks, Lee
