Developing Market Profile / TPO

The Developing Market Profile / TPO indicator provides a dynamic perspective on price-time distribution by calculating market profiles on a rolling basis. Unlike traditional session-based profiles, this tool updates bar-by-bar to show how market value develops over a user-defined lookback period, allowing traders to observe the evolution of high-activity zones in real-time.

Usage

The Usage section highlights how the indicator helps distinguish changing market behavior. By analyzing the current profile alongside historical development data, traders can identify whether the market is in a balanced state (bell shape) or trending.

• Real-time Profiling: Use the box-based histogram on the right side of the chart to identify current areas of high and low activity.
• Historical Development: The "Profile History" feature uses characters on each bar to represent the state of the profile at that specific point in time. This allows for backtesting and studying how price reacted to previous value areas as they were forming.
• Trend Identification: A shifting Point of Control (POC) or a migrating value area can signal the start of a new trend or the exhaustion of an old one.

Details

The script functions similarly to a moving average but for price distribution. For every bar, it scans a specific lookback range and segments the price action into horizontal zones (resolution).

• Occurrence Calculation: It loops through the specified lookback and counts how many times price intersected each zone. These counts are stored in an array to determine the width of the profile columns.
• Color Grading: The indicator identifies the zone with the most activity (the longest column) and assigns it a primary color. All other columns are colored based on their percentage relative to the maximum occurrence, providing a heat-map effect.
• Optimization: Because calculating a full profile for every single bar is resource-intensive, the script includes a "Calculate from here" time filter to limit the processing load to a specific starting point.

Settings

Market Profiling

• Lookback: Defines the number of historical bars used to calculate the current profile.
• Resolution: Sets the number of price rows/columns in the profile (limited to 32 for performance).

Visual Settings

• Profile Distance From Chart: Offsets the current profile boxes from the latest candle.
• Border width (MP): Adjusts the thickness of the profile box outlines.
• Character: Sets the symbol used for historical profile plotting.
• Color Theme: Allows customization of the five colors used for different percentage rankings.
• Percentage Tiers: Sets the thresholds (defaulting to 20, 40, 60, 80) for color transitions.
• Show Market Profile: Toggles the display of the current profile boxes.
• Show Profile History: Toggles the display of the historical heat-map characters.

Optimisation and Debugging

• Calculate from here: A timestamp setting to determine where the script begins its heavy calculations.
• Minimum size of histogram: Filters out very small occurrences to prevent visual artifacts or "noise" in the profile.

FAQ

How do I use this to find the Point of Control (POC)? The POC is represented by the longest column in the current profile, typically colored with the first color in your theme (e.g., Red). The script also includes built-in alerts for price crossing this level.

Why does the script only start at a certain date? Due to the complexity of calculating rolling profiles, the "Calculate from here" setting is used to ensure the script stays within TradingView's execution limits while providing historical data where it matters most.
