Ladder Levels
The Dynamic 100s & 20pt Increment Grid System is a purely mechanical, price-tracking visualizer that automatically surrounds the current price action with a highly structured, institutional-style number grid.
Instead of manually drawing horizontal levels for psychological numbers, this engine mathematically locks onto the nearest 100-point level and dynamically projects a 2,000-point grid (1,000 points above and 1,000 points below) that moves with the market in real-time.
Core Features
Major Psychological Levels (100s): The script automatically identifies the nearest whole 100-point boundary (e.g., 4100, 4200, 4300) and plots prominent, solid red lines to mark these heavy institutional and psychological barriers.
Minor Increments (20s): Within every 100-point block, the engine generates four minor sub-levels (20, 40, 60, and 80) drawn as subtle, dotted gray lines. These act as high-probability reaction zones for intraday scalps and lower-timeframe liquidity sweeps.
Dynamic Price Tracking: As the price trends upward or downward, the grid automatically shifts to ensure you are always framed perfectly in the center of the 1000-point range, preventing lines from rendering completely off-screen.
Memory Optimized: To prevent TradingView from lagging or collapsing under the weight of hundreds of drawings, the indicator utilizes a strict array-based cleanup function (barstate.islast). It only draws the grid on the live, active bar—constantly deleting and redrawing the lines without polluting your chart's history.
Best Used For:
Indices & Futures: Excellent for assets like NQ, ES, US30, or SPX where 100-point boundaries act as major support/resistance, and 20-point increments act as intraday structural steps.
ICT / Smart Money Concepts: Provides a rigid framework to anticipate liquidity sweeps (e.g., price sweeping a 20-point increment line before reversing back to the 100-point baseline).
Options Trading: Visually mapping out heavy strike price clusters which typically land on whole or 20-point increment numbers.
