Wyckoff Creek is a zone of resistance near the top of a trading range. This resistance must be overcome with a significant sign of strength to justify upside potential (jumping the creek). This sign of strength is indicated by price spread, volume action, and a strong close.
A good buying opportunity presents itself, when the stock comes back top the creek and tests at a low volume. Our markets have been in a trading range over the past 3 months. Several stocks jumped the creek recently. See NIFTY & SENSEX charts. Look through the slide shows. Buy those that backs up (coming back to ice) with lower volumes.
