PCF Name: TD Camouflage – buy signal

Tom DeMark: “ I have one approach called TD Camouflage
that works especially well short-term. It’s based on
being able to see “hidden” buying or selling pressure
as market bottoms or tops are forming.

When they talk about the market being up today or down
today, all quote vendors, newspapers and other financial
media report price change relative to the previous day’s
close. But what’s more important is price relative to
the current day’s open.

A camouflage buy indication occurs when you get a close
below the previous day’s close, but above the current
day’s open. For example, if a market closed down relative
to yesterday’s close, all the media would report that it
was a down day. But if the market is up from the open,
there’s really buying coming in. You can extend the
approach by making sure today’s low is less than the low
of two or three days ago.”

“ It’s really perfect for short-term trades. If you’re
a very short-term trader, you can use this to get in on
the close and get out the next opening. The probability
is very high for that kind of trade.”
