Technical Indicators and Signal Design in High-Frequency Trading

Article Quant Q&A · Author: nimbus3000
Read the original

Summary

The document discusses whether familiar time-series indicators such as MACD and RSI are useful as entry or exit signals in high-frequency trading. One response distinguishes visually interpreted technical analysis from quantitative finance, which generally uses numerical and statistical methods. It notes that common indicator descriptions rely on chart relationships, while the other response emphasizes that high-frequency strategies often derive signals from market microstructure.

Key ideas

  • The responses distinguish visual technical analysis from numerical quantitative methods.
  • MACD and RSI are time-series indicators rather than direct measures of order book conditions.
  • High-frequency market data may be irregularly spaced, complicating the use of conventional time-series indicators.
  • Market microstructure analysis is presented as a more typical source of high-frequency trading signals.
  • The discussion offers opinions rather than empirical evidence that any indicator succeeds or fails.

Has anyone here used technical analysis (think MACD, RSI) in HFT setting and can comment on the usage as an entry/exit signal?

Quantitative Finance is different from Technical Analysis. The essense of the difference is succinctly summarized in "Foundations of Technical Analysis: Computational Algorithms, Statistical Inference, and Empirical Implementation" article by Andrew W. Lo, Harry Mamaysky and Jiang Wang:

> Technical analysis is primarily visual, whereas quantitative finance is primarily algebraic and numerical. Therefore, technical analysis employs the tools of geometry and pattern recognition, and quantitative finance employs the tools of mathematical analysis and probability and statistics.

The above is true, in particular, for the indicators mentioned by you. For example MACD's description at Investopeida.com has the following passage:

> The MACD is often displayed with a histogram which graphs the distance between the MACD and its signal line. If the MACD is above the signal line, the histogram will be above the MACD’s baseline. If the MACD is below its signal line, the histogram will be below the MACD’s baseline.

So it is unlikely that many people here have ever used technical analysis in general and in HFT settings in particular.

HFTs use market microstructure analysis to construct their own trading signals. MACD/RSI etc are all timeseries based indicators, whereas HFT data is not uniformly spaced so if those signals had any edge (which I find extremely unlikely), they would be unsuitable anyway.
