[Pt] Periodic Volume Profile

2022년 12월 20일

This script is an attempt to recreate the Periodic Volume Profile that is built-in by TradingView, with slightly different features. Related blog: https://www.tradingview.com/blog/en/volume-profiles-new-and-improved-31068/

This script is based on another script "Volume Profile, Pivot Anchored" by dgtrd

*Note that only limited number Volume Profile can be displayed on the chart due to limitations on displaying boxes and lines.

Description
This Periodic Volume Profile (PVP) indicator allows trades to view volume profiles for periods longer than the current timeframe. The indicator builds one general volume profile for each new period, set by the user through the “Periodic Timeframe” input parameter.
This script also has the option to extend Point of Control (POC) lines with optional end conditions: Until Bar Touch, Until Last Bar, Until Bar Cross, or None, which extends to the right.
Signals are generated for Naked POC touches and crosses by a triangle symbol and a cross symbol, by default.
Alerts are available for POC touches and crosses.

What is Volume Profile?
Volume profile is a technical analysis tool that shows the volume of trades at different prices for a given security or market over a specific period of time.

Volume profile can be used to identify key levels of support and resistance, as well as to assess the overall supply and demand for a security. For example, if there is a high volume of trades at a particular price level, this may indicate that there is a significant level of support or resistance at that price. On the other hand, if there is relatively low volume at a particular price, this may indicate that there is not much interest in trading at that level.

Traders can use volume profile to identify trends, make trading decisions, and set stop-loss and take-profit orders. It can also be useful for identifying patterns such as "pockets of liquidity," which are areas where there is a high volume of trades but relatively little price movement.

It is important to note that volume profile should be used in conjunction with other technical analysis tools and should not be relied upon in isolation. It is also important to consider the overall context and market conditions when interpreting volume profile data.

Key Difference with TradingView's PVP indicator - TradingView's PVP intraday period does not align with standard intraday timeframes as it is determined by # of bars. This script provides volume profiles that aligns with higher timeframe periods.
