Exposing Hidden Market Regimes utilizing HMM4 – Analytics & Forecasts – 25 March 2025

HMM4 Indicator Documentation

Introduction

The HMM4 indicator is a robust technical evaluation instrument that makes use of a 4-Gaussian Hidden Markov Mannequin (HMM) to establish market regimes and predict potential market path. This indicator applies superior statistical strategies to cost information, permitting merchants to acknowledge bull and bear market circumstances with higher accuracy.

The indicator shows a stacked line chart in a separate window, representing the combination weights of 4 completely different Gaussian parts. These weights present useful insights into the present market state and can be utilized to make knowledgeable buying and selling choices.

Theoretical Background

Hidden Markov Fashions and Gaussian Mixtures

A Hidden Markov Mannequin (HMM) is a statistical mannequin the place the system being modeled is assumed to be a Markov course of with unobservable (hidden) states. In monetary markets, these hidden states can characterize completely different market regimes similar to bull markets, bear markets, and transitional phases.

The HMM4 indicator makes use of a steady HMM with a Gaussian combination mannequin. This strategy fashions the value information as a combination of 4 Gaussian (regular) distributions, every representing a distinct market state. The important thing benefit of this strategy is that it could actually mannequin non-normal distributions which can be generally noticed in monetary time sequence.

Market Regimes and Weight Interpretation

The 4 Gaussian parts within the mannequin could be interpreted as completely different market regimes:

Bear State – Related to growing volatility and sometimes damaging value motion Transition Bear – Transitional section transferring towards bearish circumstances Transition Bull – Transitional section transferring towards bullish circumstances Bull State – Related to lowering volatility and sometimes optimistic value motion

The weights of those parts characterize the chance of the market being in every state. These weights all the time sum to 1 (or 100%), making them straightforward to interpret as percentages.

Bull/Bear Market Identification

A key perception for buying and selling is that the cumulative weight of the primary two parts (weight1+weight2) can be utilized to establish bull and bear markets:

When weight1+weight2 > 50%, this means a bull market When weight1+weight2 < 50%, this means a bear market

This straightforward rule offers a transparent sign for potential market path and can be utilized as a part of a buying and selling technique.

Indicator Options

Visible Illustration

The HMM4 indicator shows a stacked line chart in a separate window with 5 plots:

Weight Zero (backside layer, lime shade) – All the time 0, serves because the baseline Weight 1 (inexperienced shade) – First part weight Weight 1+2 (darkish inexperienced shade) – Cumulative sum of first and second part weights Weight 1+2+3 (darkish pink shade) – Cumulative sum of first, second, and third part weights Weight 1+2+3+4 (pink shade) – All the time 1.0, as all weights sum to 1

Sorting Mechanism

The indicator kinds the Gaussian parts primarily based on the product of their means and variances (μ·σ²). This sorting ensures constant identification of the states throughout completely different time intervals, with probably the most optimistic means with the largest normal deviations ranked first (most bearish) and probably the most damaging means ranked final (most bullish).

Enter Parameters

The HMM4 indicator has the next enter parameters:

TrainingBars (default: 100) – Variety of bars to make use of for coaching the mannequin. If fewer bars can be found, the indicator will use all accessible information. EMIterations (default: 10) – Variety of iterations for the Expectation-Maximization algorithm. Increased values could present extra correct outcomes however take longer to calculate. StartBarsAgo (default: 1000) – Variety of bars in the past to start out the calculation. This determines the preliminary historic information used. UseFixedStartPoint (default: false) – When true, the indicator makes use of a set begin level for coaching information. When false, it makes use of a sliding window strategy. LineWidth (default: 1) – Width of the traces within the subplot. Alter this worth (1-5 really useful) to vary the thickness of the displayed traces.

Buying and selling Functions

Market Regime Identification

The first use of the HMM4 indicator is to establish the present market regime. By observing the stacked weights, merchants can decide whether or not the market is in a bullish or bearish state.

Buying and selling Indicators

The indicator can be utilized to generate buying and selling indicators primarily based on the cumulative weights:

Bull Market Sign – When the cumulative weight of the primary two parts (Weight 1+2) exceeds 50%, this means a bullish market setting. Merchants may contemplate lengthy positions or holding present lengthy positions. Bear Market Sign – When the cumulative weight of the primary two parts falls beneath 50%, this means a bearish market setting. Merchants may contemplate quick positions or lowering publicity to the market.

Integration with Different Indicators

For greatest outcomes, the HMM4 indicator must be used along side different technical indicators and value motion evaluation. It really works effectively as a affirmation instrument for trend-following methods and may help establish potential market turning factors.

Technical Implementation

EM Algorithm

The indicator makes use of the Expectation-Maximization (EM) algorithm, particularly a simplified Baum-Welch model algorithm, to coach the Hidden Markov Mannequin. This iterative algorithm finds the utmost chance estimates of the mannequin parameters.

Retraining Course of

The indicator retrains on every new bar by accumulating information. This adaptive strategy permits the mannequin to evolve as market circumstances change, offering up-to-date insights into the present market regime.

World Revealed Values for EA Entry

The indicator offers world revealed values with the HMM4_ prefix that may be accessed by Professional Advisors (EAs). These values characterize the newest calculated weights and are up to date on every new bar:

HMM4_Weight1 – First part weight HMM4_Weight2 – Second part weight HMM4_Weight3 – Third part weight HMM4_Weight4 – Fourth part weight HMM4_CumWeight1 – Cumulative weight 1 (identical as Weight1) HMM4_CumWeight2 – Cumulative weight 1+2 HMM4_CumWeight3 – Cumulative weight 1+2+3

EAs can entry these values instantly when the indicator is included within the EA’s chart. This permits for simple implementation of automated buying and selling methods primarily based on the HMM4 indicator’s market regime identification. For instance, an EA might implement a easy technique that goes lengthy when HMM4_CumWeight2 > 0.5 (bull market) and quick when HMM4_CumWeight2 < 0.5 (bear market).

Calculation Course of

For every bar within the calculation vary:

The indicator determines the coaching window primarily based on the UseFixedStartPoint parameter It creates a brief array for the coaching window and fills it with shut costs The HMM coaching is run on this window to find out the combination weights The weights are sorted primarily based on the product of means and variances The indicator buffers are up to date with the cumulative weights for the stacked line plot

Comparability with VIX

Whereas the unique analysis for this mannequin was utilized to the VIX (CBOE Volatility Index), the HMM4 indicator could be utilized to any monetary instrument. The benefit of this strategy is that it would not require a selected volatility index just like the VIX to establish market regimes.

The indicator instantly analyzes value information to establish completely different market states, making it relevant to any market together with foreign exchange, commodities, shares, and indices. This versatility makes it a useful instrument for merchants throughout completely different markets.

Conclusion

The HMM4 indicator offers a classy statistical strategy to market evaluation. By modeling value information as a combination of Gaussian distributions, it could actually establish completely different market regimes and supply useful insights for buying and selling choices.

The important thing benefit of this indicator is its skill to quantify the chance of the market being in several states, with a easy rule for figuring out bull and bear markets primarily based on the cumulative weights. This makes it a robust instrument for each discretionary and systematic merchants.

By adjusting the enter parameters and mixing the indicator with different technical evaluation instruments, merchants can develop strong buying and selling methods that adapt to altering market circumstances.
