BB Levels — Volatility-Based Weekly Trading Ranges
Overview
BB Levels is a precision-driven, multi-timeframe indicator designed to forecast weekly trading ranges based on market regime behavior and historical volatility. Whether you're a swing trader seeking structure or an intraday trader looking for high-probability reversals, BB Levels adapts to both.
It combines two timeframes for layered insight:
Solid Lines (Daily) → Show smoother, broader expected volatility ranges
Dashed Lines (4H) → React to local low volatility and trend shifts
How It Works
At the heart of BB Levels is a Markov Switching Model (MSM) — a probabilistic framework that classifies the market into one of three behavioral regimes: bullish, bearish, or choppy. The model constantly evaluates the likelihood of transitioning between these states and weights their expected outcomes accordingly.
Rather than simply reacting to price movement, the MSM estimates the next most probable regime and projects a directional return. This probabilistic forecast gives BB Levels a forward-looking edge most indicators lack.
Where it becomes truly powerful is in its integration with historical volatility:
The model uses average weekly volatility to project how far price is likely to travel in either direction, based on its current regime.
The weekly open acts as the anchor point — providing a consistent baseline from which volatility-driven MsM expansions are calculated.
This fusion of regime forecasting and volatility normalization results in highly adaptive price levels that respond to market tone, momentum, and range expectation — not just price extremes.
Why It's Unique
Forward Bias: BB Levels forecasts price movement probabilities, not just historical outcomes.
Market-Aware: Regime classification lets it behave differently in bull trends, bear markets, or sideways environments.
Volatility-Normalized: Uses historical volatility to create ranges that adapt to instrument and timeframe.
Timeframe Blending: Provides macro (Daily) and micro (4H) context at the same time.
Anchored Accuracy: Weekly opens give the model a stable reference point that resets cleanly week to week.
Trading Applications
Swing Traders: Use solid (Daily) levels for structure — fading extremes or playing breakouts with volatility context.
Important Notes
These levels are not hard limits, but high statistical expectations calculated using MsM and historical volatility:
Price may coil inside the dashed range during consolidation.
Strong news or momentum may push price beyond the solid range.
Flipping a level into support/resistance often signals trend continuation or mean reversion.
Designed for precision, built with statistical logic, and capable of adapting to nearly any asset class — BB Levels is your market map for the week ahead.
