Timeframe-Independent Anchored VWAPAn anchored VWAP (Volume Weighted Average Price) that produces identical values (down to the tick!) across different timeframes (unlike, for example, TradingView's built-in Anchored VWAP).
Advantages
This indicator calculates identical values whether you view it on 1m, 5m, 15m, or any other timeframe within reasonable ranges. Even challenging non-integer timeframe ratios like calculating on 2m while viewing on 3m are handled perfectly. In High or Low mode, VWAP will anchor precisely at the selected candle's high/low. As usual for AVWAP, up to 3 standard deviation bands are supported.
How to Use
Setting the Anchor: When the indicator is added, select your anchor time. This is typically placed at a significant swing high/low or session open.
Source Selection: Choose whether to anchor from High, Low, or Close price.
Calculation Timeframe: Select the timeframe used for VWAP calculation.
For intraday trading (1m-1H charts): Just keep the default setting (1m)
For swing trading (4H-D charts): Use 5m or 15m calculation timeframe
For position trading (D-W charts): Use 1H calculation timeframe
Important: Lower calculation timeframes provide more precise data but may hit Pine Script's bar limit on very long timeframes
Standard Deviation Bands: Enable additional band sets as needed for your trading style.
Technical Implementation
The indicator achieves timeframe independence through the following algorithm:
Lower Timeframe Sampling: Uses Pine Script's request.security_lower_tf() to retrieve bar data at the specified calculation timeframe, regardless of the viewing timeframe. This provides consistent data resolution across all chart timeframes.
Anchor Detection: Scans the lower timeframe data to identify the exact bar containing the selected anchor price. The algorithm handles both simple cases (where anchor falls on a complete bar) and complex cases (where anchor falls within a split bar in non-integer timeframe ratios like calculating on 2m while viewing on 3m).
FIFO Buffer Management: Maintains a First-In-First-Out buffer of lower timeframe bars. On each chart bar:
Adds new lower timeframe bars to the buffer
Processes exactly one period worth of bars (matching the viewing timeframe)
Removes processed bars from the buffer
This approach ensures consistent calculation regardless of viewing timeframe.
First Bar Initialization: On the anchor bar, processes only the single anchor bar to ensure the VWAP starts exactly at the anchor price. Subsequent bars process the full period, maintaining mathematical accuracy.
VWAP Calculation: Applies the standard volume-weighted average price formula:
VWAP = Σ(Price × Volume) / Σ(Volume)
StdDev = √(Σ(Price² × Volume) / Σ(Volume) - VWAP²)
All calculations accumulate from the anchor point forward.
Visual Continuity: For edge cases where the anchor falls in an incomplete bar (e.g., calculating on 2m while viewing on 3m), displays the anchor price as a visual placeholder until the actual calculation begins on the next bar. This ensures the line always starts visually at the anchor point.
