Triangle breakout: go long on an upward breakout and retest; if it breaks downward, short on the rebound if it fails to break above the lower boundary.
Remember, every market move that looks like a pullback is actually a major crash, and every move that looks like a major crash is actually just a pullback.
An engulfing pattern appears at the top of an uptrend, accompanied by high trading volume, indicating a high possibility of a market reversal. This is suitable for left-side trading and can be used to go short.
