LBB Indicator - Clean Build

50
**LBB (Liquidity-Based Bands) Indicator - Professional Trading Tool**

The LBB Indicator is a sophisticated price action tool designed for futures and forex traders who focus on liquidity sweeps and session-based analysis. This indicator automatically tracks key liquidity levels across multiple trading sessions (Asia, London, Overnight, and US Trading Day) and creates dynamic trading zones based on untested price levels. By identifying where liquidity remains uncontested, traders can better anticipate institutional order flow and potential reversals at critical price levels.

The indicator features intelligent session tracking that monitors high and low prices during each major market session, automatically freezing these levels when sessions close and making them available for analysis. These session levels are labeled with clear naming conventions (AsiaH/AsiaL, LonH/LonL, ONH/ONL, PDH/PDL) and include aging markers (D1, D2, D3) to show how long levels have remained untested. When price touches a liquidity level, it's immediately marked as "tested" with a dotted line style, ensuring traders always know which levels remain virgin and which have been swept.

The core functionality centers around dynamic zone creation during the US trading session (0500-0900 PST). Zones are built using the closest untested liquidity levels above and below the current price, creating a bounded trading range with three distinct bands: a bull zone (upper 35%), a no-trade zone (middle 30%), and a bear zone (lower 35%). The indicator includes a preview feature that shows where the next zone will form based on price position within the current bands. When a zone boundary is tested or its underlying liquidity level is swept, the zone automatically recalculates using fresh untested levels, ensuring traders are always working with valid reference points.

Advanced features include automatic level aging at the New York close (1300 PST), customizable maximum age for old levels, synthetic level generation when natural liquidity is exhausted, and time-based line rendering that maintains visual clarity across historical data. The indicator respects the freeze-test-advance lifecycle, ensuring levels can only be tested after their formation session closes, preventing false signals during active price discovery periods. With support for both standard and extended London sessions, comprehensive session overlap handling, and intelligent cleanup of tested levels, the LBB Indicator provides professional traders with a complete framework for liquidity-based trading strategies.
