Cập nhật Anchored OBV + A/D
Anchored OBV + A/D is a single-pane indicator that allows On-Balance Volume (OBV) and Accumulation/Distribution (A/D) to be plotted together using a period-anchored approach.
OBV and A/D are cumulative by nature, which makes their full-history absolute values arbitrary and often incomparable when plotted side-by-side . This script addresses that limitation by anchoring each indicator to a user-defined period (daily, weekly, monthly, etc.) and plotting their relative change from that baseline rather than their raw values. The result is a comparison that preserves each indicator’s internal structure (trends, inflections, and divergences) while minimizing scale conflicts.
How it Works
At the start of each selected anchor period, the script records the current OBV and A/D values as baselines. All subsequent values are plotted as changes relative to those baselines:
- Percent mode measures the % change from the baseline.
- Delta mode measures the absolute change from the baseline.
Optional anchor markers and a zero line make it easy to see when resets occur and how each indicator behaves relative to the period’s starting point.
Advantages vs using OBV and A/D separately
- Direct visual comparison: Both indicators are on the same anchored scale, making relative movement immediately readable.
- Preserved analytical structure: Trends, inflections, and divergences remain intact; time-based shape is not distorted.
- Cleaner workflow: One indicator, one pane, and less chart clutter.
Interpretation
- Values above zero indicate net accumulation or positive volume pressure since the anchor.
- Values below zero indicate net distribution or negative volume pressure since the anchor.
- Trend confirmation: Rising price accompanied by rising anchored OBV and A/D suggests healthy participation.
- Price Divergence: Price making new highs or lows while one or both indicators fail to confirm can indicate weakening participation or a potential change in behavior.
- OBV vs A/D Interaction: When both move together, volume and close-location effects broadly agree. When they diverge, it highlights differences between net up/down volume (OBV) and intrabar accumulation/distribution (A/D).
Warnings!
- Percent mode can become visually unstable when baseline OBV or A/D values are near zero due to division effects inherent in percent-change calculations.
- It is not recommended to interpret structure across periods as each period is relative to a different baseline. Structure is not preserved across periods - only within each individual period.
