## High-Frequency Noise Filtering

High-frequency noise filtering is the process of removing microstructure noise from price data to reveal the underlying trend. This involves mathematical techniques such as averaging, wavelets, or kernel smoothing.

By isolating the true price signal, traders can make better decisions regarding entry and exit points. This is particularly important for quantitative strategies that operate on short time frames.

Without effective filtering, these models are prone to overfitting and poor performance in live markets. It is a necessary step in preparing data for robust algorithmic trading systems.
