Closing price reversal
Is a technical pattern that signals a change in trend. When supply is greater than demand for securities, price falls to find adequate demand. When the demand below a previous close is significant enough to bring prices to close above the previous close. A CPR or closing price reversal has occurred. The closing price has reversed its trend. In this case from down it up.
The reverse is true at a top. Prices go to a new high above the previous days close. The buying pressure is not strong enough to keep it up there, so prices close lower than before.
