Cumulative Volume Delta with VWAP-based Buy/Sell Alerts

4 thg 10

Description:
This script combines Cumulative Volume Delta (CVD) with Volume Weighted Average Price (VWAP) to generate buy and sell signals. It plots both the cumulative volume delta and its moving average on the chart, but the actual buy and sell signals are now based on the crossover and crossunder of the price with the VWAP, a popular tool for tracking price relative to the volume-weighted average over time.

Features:
Cumulative Volume Delta (CVD) Plot:
CVD helps visualize the net buying or selling pressure by accumulating volume when the price is rising and subtracting it when the price is falling. The cumulative volume is plotted on the chart as a blue line.

Moving Average of CVD:
A simple moving average (SMA) of the cumulative volume delta is plotted in orange to smooth out fluctuations and help detect the trend of volume flow.

VWAP Calculation:
VWAP (Volume Weighted Average Price) is a standard benchmark widely used in trading. It gives insight into whether the price is trading above or below the average price at which most of the volume has traded, weighted by volume. The VWAP is plotted as a purple line on the chart.

Buy/Sell Signals Based on VWAP:

Buy Signal: Triggered when the price crosses above the VWAP, indicating potential upward momentum.
Sell Signal: Triggered when the price crosses below the VWAP, signaling potential downward momentum.
These signals are displayed on the chart with clear labels:

Buy Signal: A green upward label appears below the price.
Sell Signal: A red downward label appears above the price.
Alerts for Buy/Sell Conditions:
Alerts are built into the script, so traders can receive notifications when the following conditions are met:

Buy Alert: The price crosses above the VWAP.
Sell Alert: The price crosses below the VWAP.

Use Case:
This script is useful for traders looking to incorporate both volume-based indicators and the VWAP into their trading strategy. The combination of CVD and VWAP provides a more comprehensive view of both price and volume dynamics:

VWAP helps traders understand whether the price is trading above or below its volume-weighted average.
CVD highlights buying or selling pressure through cumulative volume analysis.

Customization:
Anchor Periods: The user can customize the anchor period to suit different timeframes and trading styles.
Custom Alerts: The alert conditions can be easily modified to integrate into any trader’s strategy.
This script can be adapted for both short-term and long-term trading strategies and is especially useful in high-volume markets.

How to Use:
Add the script to your TradingView chart.
Customize the timeframe and anchor period, if needed, to match your preferred trading style.
Watch for Buy/Sell signals based on price crossing the VWAP.
Set up alerts to receive notifications when Buy or Sell signals are triggered.
This script is designed to help traders make informed decisions based on both price action relative to volume and Cumulative Delta volume trends, giving a more comprehensive view of the market dynamics.
