Meridian Stochastic Regime Suite [JOAT]

Meridian Stochastic Regime Suite [JOAT]

Introduction

Meridian Stochastic Regime Suite is an open-source adaptive oscillator built for traders who want more context than a standard stochastic line can provide. The script combines a centered stochastic engine, an adaptive response model, and a regime profile so the oscillator changes character as the market shifts between trend, compression, expansion, and balance.

The problem Meridian solves is signal quality. Standard oscillators often look clean, but they do not explain whether momentum is occurring inside a compressed market, an expanding breakout phase, or a stable trend. Meridian adds that context directly into the oscillator architecture so the same reading can be interpreted differently depending on the active regime profile.



Core Concepts

1. Centered stochastic architecture

Price is pre-smoothed first, then converted into a stochastic reading that is centered around 50 so directional pressure is easy to interpret:

smoothHigh  = ta.ema(high, priceSmoothLen)
smoothLow   = ta.ema(low, priceSmoothLen)
smoothClose = ta.ema(close, priceSmoothLen)
rawStoch    = 100.0 * (smoothClose - ta.lowest(smoothLow, stochLen)) / stochRange

2. Adaptive response engine

The main oscillator does not use static smoothing alone. Its response speed and gain expand or contract based on the regime profile:

gainBias  = gainBase + trendScore * 0.38 + expansionScore * 0.18 - compressionScore * 0.12
speedBias = responseBase + trendScore * 0.08 + expansionScore * 0.04
adaptiveOsc := adaptiveOsc[1] + speedBias * (adaptiveSeed - adaptiveOsc[1])

This helps the oscillator respond differently in directional and compressed conditions.

3. Embedded regime scoring

Meridian computes four internal state scores:

• Trend
• Compression
• Expansion
• Balance

Those scores are derived from ATR behavior, path efficiency, and slope strength, then normalized into a regime profile shown in the dashboard.

4. Spread and signal layer

The script compares the adaptive oscillator to a slower signal line and visualizes the spread around the neutral axis. This gives a direct view of acceleration versus drag.

5. Institutional oscillator panel

The panel uses restrained zones, layered fills, and a top-right dashboard instead of loud markers. The result stays readable while still carrying multiple analytical dimensions.



Features

• Centered stochastic core: Keeps the oscillator readable around a neutral midpoint
• Adaptive response model: Gain and speed shift with the internal regime profile

• Regime dashboard: Displays state, confidence, adaptive reading, signal reading, and regime profile shares
• Confirmed-bar flips: Internal state transitions are tracked on closed bars
• Non-repainting design: Uses only current-timeframe data and no future references

How to Use This Indicator

Step 1: Start with the regime
Read the dashboard first. Trend and Expansion regimes support directional interpretation. Compression and Balance call for more caution.

Step 2: Watch adaptive versus signal spread
When the adaptive line separates cleanly from the signal line, momentum is strengthening. When the spread compresses, the move is losing urgency.

Step 3: Use the centered fast line as timing context
The fast line helps show whether short-term momentum is leading or lagging the adaptive engine.

Step 4: Avoid isolated readings
Meridian is strongest when used alongside a structure or value-based tool rather than as a standalone trade trigger.

Indicator Limitations

• Like all oscillators, Meridian can remain elevated or depressed during strong directional trends
• Compression states may delay re-acceleration readings until volatility expands again
• The regime profile is descriptive, not predictive

Originality Statement

Meridian Stochastic Regime Suite is original in how it embeds a four-state regime profile directly into the adaptive behavior of a centered stochastic engine. It is published because:

• The oscillator response changes with internal market-state measurements instead of using only fixed smoothing
• The script surfaces trend, compression, expansion, and balance as percentages inside the same panel
• The panel and dashboard design turn regime context into an interpretable momentum framework rather than a generic stochastic clone
