Rising Wedge Patterns forms with Higher Highs and Higher Lows.
Rising Wedge pattern basically forms in two shapes - 1) If rising wedge pattern forms in an uptrend it will make reversal and 2) If rising wedge pattern forms in a downtrend it will make continuation.
The higher highs and the lower lows along makes a trend resistance and trend support. When breakout occurs downside, price breaks the trend support line
