(VIP) VSA Scanner v2

This script is major rewritten from scratch analysis of Volume Spread Analysis in comparison to previous version. New definitions have been added, calculations of Spread, Volume and Trend have been optimised and signals are much more accurate. I created script based on definitions coming from methodology of Volume Spread Analysis. Signals appearing below candle are treated as SOS (Signal of Strength) and those above candles - SOW (Signal of Weakness). Also we can see automatic identification of Bullish / Bearish Volume . Script is judging Spread and Volume used for identifying VSA Signals based on multiple factors. Also analysis of Effort & Result have been added, easily allowing to spot continuations of trend and divergences.

All major signals from VSA have been added like Stopping Volume, Climaxes, End of Rising Market, Bag Holding etc.

In case of interest, please contact me directly via DM on Tradingview or please see link to documentation from my signature where you can find more information about Subscription and script itself.

發布通知:

Corrected signals definitions from original VSA methodology.

There are four categories of signals now marked as below:

• Cross and Diamond - major signals predicting possible trend reversal
  
• Circle - Signals of Weakness/Strength
  
• Triangle - Tests from VSA methodology
  
• Flag - is displaying signals when Supply/Demand Zone were broken
  

Ideal scenario would be to get firsty Cross or Diamond Signal, then Circle and Triangle - but it's not always happening. It's individual judgement of trader what makes a difference and can turn signals from VSA Scanner into profitable trade.
There are also drawn Supply (orange) and Demand Zones (blue).

Scanner is not displaying all Wyckoff's nor VSA signals in order to simplify things but I tried to reflect as much as possible in it - that's why we have also Strength and Weakness Signals or Confirmations being displayed on chart.

Bugfix - restore original functionalities of Volume Zones & Auto-Adaptive Moving Average that disappeared (by mistake!) within previous update
