P-Value Interpretation
The P-value represents the probability of obtaining test results at least as extreme as the results actually observed, assuming the null hypothesis is true. In high-frequency cryptocurrency trading, a low P-value is often used to justify the execution of automated strategies by suggesting the observed signal is not random.
However, practitioners must be cautious, as a low P-value does not guarantee that the effect is large or practically useful, only that it is unlikely to have occurred by chance. Misinterpreting this value can lead to significant losses if traders confuse statistical significance with economic significance.
It serves as a tool for decision-making under uncertainty, helping to filter out noise in volatile derivative markets. Proper interpretation requires setting a significance level beforehand to avoid p-hacking.
