Quote from Mercor:
Me too. I only use my "Big Move" system to trade the S&P.
It always keeps me away from those choppy and small trades.
We're both so smart!

i watch the uvol/dvol its not quite the same,what would i be looking for in the adv/decQuote from Trading4Living:
The envelope is just a secondary confirmation tool. I watch the ADV/DEC chart the first 30 mins of the day if it's not moving strong enough then I wont trade
If it hits the marks then I am good to trade.
