Also...
Falling volume is how bear markets are made.
To look for tops, you want to see heavy volume on green days, not red days.
Bigger questions...
what is the basis used for determining "bottom", "falling", "heavy", and "top"?
do the above rules apply to all time frames?
To be clear, I'm not saying we are in a bull market.
I'm saying bull markets have rising prices on low volume. So just because it's going up on low volume isn't anything special *except* it's a bear market - though technically S&P is not a 20% down bear market and neither is DOW I think. So only Nasdaq.
