I like to use the triple top method or triple bottom methods.
Investopedia is a great resourse for learning in seems you have already dose some digging into it anyway.
This little guide helps me a lot
Triple Tops: Identification GuidelinePrice trend Upward leading to the pattern.Shape Three peaks near the same price with a downward breakout.
Middle peak Sometimes the middle peak is priced marginally below the other two.
Volume Trends downward 59% of the time, but is usually high beneath formation of each peak.
Bear market More triple tops appear in a bear market than in a bull one.
Confirmation The pattern becomes valid when price closes below the lowest valley in the pattern.
Triple Tops: Trading TipsTrading Tactic ExplanationMeasure rule Compute the height from the highest peak (point B in the Measure Rule figure to the right) to the lowest valley (A) and then multiply it by the above “percentage meeting price target.” Subtract the result from the lowest valley (A) to get a price target (C).
Price reversal Price must have something to reverse, so if the rise leading to the pattern is small, expect a small decline.
Confirmation Wait for price to close below the lowest valley (confirmation, point A in the Measure Rule figure to the upper right) before placing a trade.
Peaks When the last peak (point B in the Peaks figure to the right) is below the middle one (A), then expect a stronger decline. A lower top suggests weakness as price attempts to make a new high but fails.
Price velocity A high velocity rise leading to the pattern often results in a larger decline post breakout.
Yearly high Patterns in the highest third of the yearly price range perform best.
Volume trend An upward volume trend suggests better post breakout performance.
Quick decline A quarter of the tops reach the ultimate low in the first week after a breakout. A third bottom in less than 2 weeks.
