Put-Call Ratio
The put-call ratio is a technical indicator calculated by dividing the trading volume or open interest of put options by that of call options for a specific asset. In options trading, a put option gives the holder the right to sell an asset, while a call option gives the right to buy.
A high put-call ratio suggests that investors are purchasing more protection or betting on a price decline, which is often interpreted as a bearish sentiment. Conversely, a low ratio indicates that market participants are favoring calls, signaling bullish expectations.
In crypto derivatives, this ratio helps reveal the hedging activity of institutional players. If the ratio reaches an unusually high level, contrarian traders might view it as a signal that the market is oversold and due for a bounce.
It provides a snapshot of market positioning and risk appetite. By monitoring shifts in this ratio, traders can gauge how the market is hedging against potential volatility.
It is a fundamental tool for understanding the demand for downside protection versus upside speculation.
