SymmetricaTriangle（对称三角形）
Symmetrical TriangleThe symmetrical triangle, whichcan also be referred to as a coil, usually forms during a trend as acontinuation pattern. The pattern contains at least two lower highs and twohigher lows. When these points are connected, the lines converge as they areextended and the symmetrical triangle takes shape. You could also think of itas a contracting wedge, wide at the beginning and narrowing over time.
Trend: In order to qualify as acontinuation pattern, an established trend (at least a few months old) shouldexist. The symmetrical triangle marks a consolidation period before continuingafter the breakout.
Four (4) Points: At least 2 pointsare required to form a trend line and 2 trend lines are required to form asymmetrical triangle. Therefore, a minimum of 4 points are required to beginconsidering a formation as a symmetrical triangle. The second high (2) shouldbe lower than the first (1) and the upper line should slope down. The secondlow (2) should be higher than the first (1) and the lower line should slope up.Ideally, the pattern will form with 6 points (3 on each side) before a breakoutoccurs.
Volume: As the symmetricaltriangle extends and the trading range contracts, volume should start todiminish. This refers to the quiet before the storm, or the tighteningconsolidation before the breakout.
Duration: The symmetrical triangle can extend for a few weeks or many months. If the pattern is less than 3 weeks, it is usually considered a pennant..
Breakout Timeframe: The ideal breakout point occurs 1/2 to 3/4 of the way through the pattern's development or time-span. The time-span of the pattern can be measured from the apex (convergence of upper and lower lines) back to The beginning of the lower trend line (base). A break before the 1/2 way point might be premature and a break too close to the apex may be insignificant. After all, as the apex approaches, a breakout must occur sometime.
Breakout Direction: The future direction of the breakout can only be determined after the break has occurred. Sounds slightly enough, but attempting to guess the direction of the breakout can be dangerous. Even though a continuation pattern is supposed to breakout in the direction of the Long-term trend, this is not always the case.
Breakout Confirmation: A break should be on a closing basis for it to be considered valid. Some traders apply a price (3% break) or time (sustained for 3 days) filter to confirm validity. The breakout should occur with an expansion in volume , especially on upside breakouts.
The return to the apex or a support/resistance level around the breakout before resuming in the direction of the breakout.
Price Target: There are two methods to estimate the extent of the move after the breakout. First, the widest distance of the symmetrical triangle can be measured and applied to the breakout point. Second, a trend line can be drawn parallel to the pattern's trend Line that slopes (up or down) in the direction of the break. The extension of this line will mark a potential breakout target.

对称三角形，也可以称为线圈，通常在趋势中形成为连续模式。该模式包含至少两个较低的高点和两个较低的低点。当连接这些点时，线条在它们延伸时会聚并且对称三角形成形。你也可以把它想象成一个收缩的楔形，一开始就是宽的，随着时间的推移变窄。
趋势：为了有资格作为连续性模式，已确定的趋势（至少几个月）承担。对称三角形标志着在突破后继续之前的巩固期。
四（4）点：形成趋势线需要至少2个点，形成不对称三角形需要2个趋势线。因此，需要至少4个点来开始将地层视为对称三角形。第二个高点（2）应该低于第一个（1），上面的线应该向下倾斜。第二个低（2）应该高于第一个（1），下面的线应该向上倾斜。理想情况下，在突破发生之前，模式将形成6个点（每侧3个）。
成交量：随着对称三角形的延伸和交易区间的收缩，成交量应该开始减少。这指的是风暴前的安静，或突破前的紧缩。
持续时间：对称三角形可以延续几周或几个月。如果模式少于3周，通常被认为是三角旗..
突破时间框架：理想的突破点发生在模式开发或时间跨度的1/2到3/4之间。模式的时间跨度可以从顶点（上下线的收敛）测量回到下趋势线（基线）的开始。在1/2路点之前的中断可能是过早的，并且太靠近顶点的中断可能是微不足道的。毕竟，随着顶点接近，必须在某个时候发生突破。
突破方向：突破的未来方向只能在突破发生后确定。听起来有点小，但试图猜测突破的方向可能很危险。尽管延续模式应该在长期趋势的方向上突破，但情况并非总是如此。
突破确认：休息应该在收盘时才能被视为有效。一些交易者应用价格（3％休息）或时间（持续3天）过滤器来确认有效性。突破应该随着交易量的增加而发生，特别是在上行突破时。
在突破方向恢复之前，返回到突破周围的顶点或支撑/阻力位。
价格目标：有两种方法可以估算突破后的移动幅度。首先，可以测量对称三角形的最宽距离并将其应用于突破点。其次，趋势线可以平行于模式的趋势线绘制，该趋势线在中断方向上倾斜（向上或向下）。该线的延伸将标志着潜在的突破目标。
