## Neckline Breakout

The neckline is the critical horizontal or diagonal support or resistance line that connects the reaction lows of a double top or the reaction highs of a double bottom. A breakout occurs when the price decisively closes beyond this line, confirming the reversal pattern.

In the context of derivatives, this often triggers automated stop-loss orders and liquidations, accelerating the price move. Traders view the neckline as the line of demarcation between the prevailing trend and the new trend.

A failure to hold the breakout level can lead to a trap, where the price quickly returns to the previous range. High liquidity at the neckline is common due to the concentration of orders.

Analyzing the strength of the breakout involves assessing the speed and volume of the price move. It is a pivotal moment for risk management, as traders adjust positions based on the new direction.

The neckline serves as a foundational element for technical entry strategies.
