How to identify the pattern
A double top resembles the letter "M": a rise, a peak, a pullback, a failed attempt at roughly the same level, then a decline. A double bottom is its mirror and resembles a "W".
Conditions for correct identification:
- A clear prior trend: this is a reversal pattern, so it must follow an advance (for a double top) or a decline (for a double bottom).
- Two comparable peaks: not necessarily identical; a small difference is normal.
- A defined neckline: the pullback level between the two peaks, which is the key to confirmation.
Confirmation and target calculation
The pattern is incomplete until price closes beyond the neckline. Entering before that is speculating on a scenario that has not yet occurred.
Target calculation: measure the pattern height (peak to neckline) and project it from the break point:
Target = neckline − (peak − neckline)
Example: a peak at 2420 with the neckline at 2400 → a height of $20, giving an approximate target of 2380 and a stop above 2420. This yields a measurable reward-to-risk before entry — the correct way to evaluate any pattern.
Why the pattern sometimes fails
No chart pattern is guaranteed, and this one most often fails in two situations:
- False breakout: price breaks the neckline, triggers stops, then reclaims it — common on gold given its volatility.
- A trend stronger than the pattern: in a powerful uptrend an apparent double top can be merely a pause before the advance resumes.
To reduce this: wait for a candle close beyond the neckline, and combine the pattern with larger support and resistance levels rather than relying on it alone.
