It's not abonormal volumes you're looking for--a better way to look
at it is certain volume changes often preceed a stock price change.
However, you will find that the size of the change varies greatly
from stock to stock, but it's often consist for a particular stock.
Take a moving average of the volume.
Mov(volume,periods,sma) and then multiply it by the amount you want
the volume to change by---10% or 50% or whatever
V>Mov(volume,periods,sma)*1.10
So both the length of the moving average and the percentage change
impact the frequency of the event. If you make the percentage too
big, you won't find the condition often enough to matter. It takes
some experimenting. 30 to 50 period MAs are good and volume spikes in
the 20% to 50% range are good.
You put that in the systems tester, or in an indicator, and wow,
we're going to make money now.
What you really should do is read Roy's newsletter and find out how
to do explorations properly to find stocks that actually have a high
probability of making a move. He's got a great series on explorations
in Dec, Jan and Feb.
