## Data Cleaning Techniques

Data cleaning techniques in the context of cryptocurrency and financial derivatives involve the systematic process of detecting and correcting corrupt, inaccurate, or irrelevant records from raw datasets. In high-frequency trading and order flow analysis, raw exchange data often contains noise, missing timestamps, or duplicate trades that can distort quantitative models.

Analysts apply filtering algorithms to remove outliers, synchronize asynchronous data feeds, and handle gaps in price discovery mechanisms. This process ensures that backtesting engines and risk management protocols operate on high-fidelity, reliable information.

By standardizing disparate data formats from various exchanges, these techniques facilitate accurate calculation of volatility, Greeks, and other risk sensitivities. Proper cleaning is the foundational step before deploying any algorithmic strategy to ensure that signal detection is not based on artifacts or transmission errors.
