Avoid the open. They see YOU coming sucker. Look for downtrends to reverse after a top, two lower highs and a double bottom. Bulls live above the 200 day, bears live below. Sellers eat up rallies below this key moving average line and buyers to come to the rescue above it.
Price has memory.
Chances are it will do it again. Big volume kills moves. Climax blow-offs take both buyers and sellers out of the market and lead to sideways action. Trends never turn on a dime. Reversals build slowly.
