Volume Detection NZS + Alert
Volume Detection NZSDescriptionThe Volume Detection NZS is a visual analysis tool designed to identify significant liquidity events and categorize the underlying "pressure" (buying vs. selling) behind those spikes. Unlike standard volume bars, this indicator isolates high-activity candles and uses a weighted calculation to estimate how much of that volume was driven by aggressive buyers versus aggressive sellers.How It WorksThe script operates on two primary layers: Spike Detection and Pressure Attribution.Volume Spike Logic:The indicator calculates a Simple Moving Average (SMA) of volume over a user-defined period (default is 20). A "Spike" is triggered only when the current bar's volume exceeds this SMA multiplied by a specific threshold (default 1.5x).$[ \text{Volume} > (\text{SMA}(\text{Volume, 20}) \times 1.5) ]$Pressure Calculation (The "Inside" Volume):Instead of simply looking at whether a candle closed green or red, the script uses the candle's range and close position to attribute volume:Buy Volume: Estimated based on how close the price finished to the high of the candle.Sell Volume: Estimated based on how close the price finished to the low.Delta: The difference between these two determines if the bar is labeled as "Buying" or "Selling" pressure.Visual Elements:Bar Coloring: The chart bars only change color during a Volume Spike. Bullish spikes turn bright green; Bearish spikes turn dark/black.Dashboard: A real-time table in the top-right corner displays the raw Buy/Sell volume breakdown and the current pressure status for the active candle.How to UseTrend Confirmation: Use the green spikes to confirm the strength of a breakout or the start of a new bullish leg.Exhaustion Signals: Large spikes at the end of an extended move can signal "climax" volume, suggesting a potential reversal.Filtering Noise: Because the indicator only colors bars on significant volume spikes, it helps traders ignore low-liquidity chop.SettingsVolume MA Length: Adjusts the lookback period for what the script considers "normal" volume.Volume Spike Multiplier: Higher values make the indicator more selective, only highlighting the most extreme volume events.
