Telah dikemas kini Trapped Trader Ledger
The primary purpose of the "Trapped Trader Ledger" is to provide a real-time, order-flow-based visualization of market liquidity and directional imbalance within a defined lookback window. By partitioning the price range into discrete volume bins, the indicator systematically categorizes buying and selling pressure, allowing you to instantly identify where significant volume has accumulated and where the market is currently experiencing "trapped" liquidity. It transforms raw volume data into a structured profile, effectively exposing the battle between supply and demand that often dictates future price action.
To use this tool effectively, monitor the dashboard on your desired timeframe while paying close attention to the Point of Control (POC), highlighted in yellow both on the chart and in the table. The table serves as your primary diagnostic tool: look for rows where the Ratio and Delta columns indicate high directional dominance, as these are the zones where trapped participants are most likely to react if price returns to their position. Use the widthScale input to adjust the visual histogram intensity to your preference, and ensure your lookback window is set to a length that captures the relevant market cycle you are currently trading.
The rationale behind this approach is rooted in the "Value Area" theory, which posits that price tends to gravitate toward areas of high volume accumulation. By calculating the Delta and Relative Volume for each specific price bin, the script filters out market noise and focuses on "high-conviction" levels—where the discrepancy between buyers and sellers is largest. This methodology assumes that when price leaves an area of high volume imbalance, the participants who were positioned on the losing side become "trapped," creating significant pressure for a potential reversal or liquidity-driven breakout when those levels are re-tested.

Nota Keluaran
The binning formula was corrected so each price bin is computed using a stable binSize instead of a drifting priceSpan multiplier.Bins were stabilized so they no longer shift every bar when the rolling high–low range changes.
The midpoint‑based volume assignment was removed to eliminate distortion from collapsing the entire bar into one artificial price.
The top‑bin compression caused by (numBins - 1) was eliminated to ensure uniform bin boundaries.
The POC calculation was corrected so it reflects the true highest‑volume bin rather than the highest‑volume midpoint approximation.
The rolling ledger update was cleaned so old volume is removed from the correct bin without misalignment.
Line rendering was fixed to delete old lines before drawing new ones, preventing ghost lines and inconsistent widths.
The table was restored with improved formatting, clearer highlights, and consistent color logic while preserving all original metrics.
