Option skew and perpetual contract funding rates are like two different "thermometers" measuring different dimensions of the market. When they conflict, it usually does not mean one replaces the other. Instead, it reflects different layers of market sentiment.

In terms of leading signals, option skew (especially 25-delta skew) tends to be more directionally predictive, because it represents the cost that "smart money" and institutional funds are willing to pay for tail risk. When it diverges from the retail-driven funding rate signal, you should be cautious about the sustainability of short-term price moves.
How to Read the Two Signals
Option Skew: Institutional defensive sentiment. When put options are more expensive than call options (positive skew), it reflects that institutions are increasing hedging costs. This is usually a leading indicator of market pressure or expected downside. This type of trading involves large capital and complexity, and participants are mostly professional institutions, so it may signal a potential shift.
Perpetual Funding Rate: Retail trading sentiment. A positive funding rate means longs are dominant and market sentiment is overheated. A negative rate means the opposite. Funding rates are mainly driven by directional bets from retail traders or short-term speculators. They are more volatile but often lag behind price trends, and can give false signals in extreme market sentiment.
How to Judge When a Conflict Happens
If you see option skew has turned positive (put options are getting more expensive), but the funding rate is still positive (retail traders are still going long), this shows a market divergence. Institutions are paying for protection while retail traders are still chasing the rally. In this case, the sustainability of the move is usually questionable. The upswing may be near its end, and you should watch for pullback risk.
If you see option skew is negative (call options are getting more expensive), but the funding rate is negative (retail traders are shorting), institutions are betting on an upside breakout while retail traders are panic shorting. This often suggests the bottom may be near, a one-sided downtrend may be hard to sustain, and the market may stabilize or even reverse.

How to Use This Signal
Priority reference: When the two signals point in opposite directions, you can lean toward option skew as a guide. It reflects more medium-to-long-term logic and institutional behavior, while the funding rate works better as a supplementary indicator of market sentiment.
Wait for sentiment alignment: The most reliable signal is when both indicators point in the same direction. For example, if skew turns negative and the funding rate turns negative, it may signal a trending rally. If skew is positive and the funding rate is positive, defensive demand is stronger. When divergence appears, you should be more cautious about directional judgment.
