Volume Flow Indicator

A custom indicator created by TrendSpider Team on TrendSpider. You can import this custom indicator into your TrendSpider account. Don't have TrendSpider? Create an account first, then import the custom indicator.

The Volume Flow Indicator (VFI) is a sophisticated technical analysis tool designed for the lower panel of a trading chart, aiming to identify major trends by analyzing volume flows and price movements. This indicator combines several elements to assess buying and selling pressure, incorporating volatility, volume, and price movement into its calculation to offer insights into the potential direction of market trends.
