What Defines a Strong Breakout vs. False Breakout?

 

I’d like to discuss the difference between what we often call a “strong breakout” and a “false breakout”. What criteria do you personally use (candlestick body size, volume, retest behavior, multi-timeframe confirmation)?

My observation: sometimes a breakout above recent highs comes with strong follow-through, but other times it fails quickly and returns inside the range. Curious how experienced members differentiate these cases.
