A narrow range is a weak and balanced price movement pattern with less price volatility and less risk.
Wide fluctuation is a kind of energy consumption type price trend pattern, the price fluctuation is sharp, the risk will increase.
The convergent triangle is caused by the temporary balance between the long and short sides in a certain price area. This pattern usually consists of more than two high points and low points, and the high points gradually decrease, the low points gradually increase, and the price change range changes from large to small, and from wide to narrow.
The trading volume decreases from left to right, and the price fluctuation amplitude and trading volume changes at the tail end are relatively stable. The trend breakthrough is accompanied by a significant increase in trading volume, but the direction is unclear, and it can be up or down.
In a downward trend, when the support line of the bottom side of the convergent triangle is broken and a large decline occurs (generally about 3% beyond the top side of the convergent triangle), it can be preliminarily confirmed that the downward breakthrough of the convergent triangle is effective.
