What is shark pattern in trading?

Could you please elaborate on the concept of a "shark pattern" in trading? I'm curious to understand how it's identified, what it signifies in the market, and how traders might utilize this pattern to inform their decision-making processes. Is it a reliable indicator of future price movements, or does it require additional analysis for context? Additionally, are there any specific charting tools or strategies that traders commonly employ to identify and trade the shark pattern effectively?
