A double top is a bearish reversal chart pattern that typically signals the end of an uptrend and the beginning of a downtrend. It is one of the most common and reliable patterns in technical analysis, indicating that the asset may have reached a significant resistance level.

### Characteristics of a Double Top

1. **Shape**: The double top pattern resembles the letter "M" with two distinct peaks (tops) at approximately the same price level, separated by a moderate trough (valley).

2. **Peaks and Troughs**:
- **First Peak**: The price reaches a high point and then declines.
- **Trough**: After the first peak, the price falls to form a low point.
- **Second Peak**: The price rises again to a level close to the first peak but fails to break through the resistance, then declines once more.

3. **Neckline**: The trough (valley) between the two peaks forms a support level known as the neckline. This is a key level that traders watch for a breakout.

### Trading the Double Top

To effectively trade a double top pattern, traders generally follow these steps:

1. **Identify the Pattern**: Recognize the formation of two peaks at nearly the same level, with a trough in between.

2. **Confirmation**: Wait for the price to break below the neckline (the support level at the trough). This breakout confirms the pattern and suggests a bearish reversal.

3. **Entry Point**: Enter a short position (or sell) at the point where the price breaks below the neckline.

4. **Stop-Loss Placement**: Place a stop-loss order above the second peak to manage risk. This helps protect against false breakouts.

5. **Target Price**: Measure the distance from the peak to the neckline. Subtract this distance from the breakout point to set a potential target price. This gives an estimate of the expected price movement following the pattern's completion.

### Example

Here’s an illustrative example of a double top pattern:

1. **Formation**:
- The price of a stock rises to $50 (first peak) and then declines to $45 (trough).
- It rises again to $50 (second peak) but fails to break above this level.
- The price then falls back to $45 (neckline).

2. **Confirmation and Breakout**:
- The price breaks below $45, confirming the double top pattern.

3. **Trade Execution**:
- Enter a short position at the breakout point ($45).
- Place a stop-loss order above the second peak (e.g., $51) to manage risk.
- Set a target price by measuring the distance from the peak to the neckline ($50 - $45 = $5). Subtract this distance from the breakout point ($45 - $5 = $40) for a target price of $40.

### Psychological Aspect

The double top pattern reflects a battle between buyers and sellers. The first peak indicates resistance where sellers overpower buyers, leading to a decline. The second peak confirms that buyers are unable to push the price higher, reinforcing the resistance level. The failure to break above this resistance level and the subsequent break below the neckline signal a shift in sentiment from bullish to bearish.

Understanding and identifying the double top pattern can help traders anticipate potential reversals and make more informed trading decisions.
