Introducing Congestion Zone Detection Logic:
The script now detects congestion zones based on gaps formed between consecutive bars. Specifically, it checks whether the size of the gaps meets certain criteria, which are defined through inputs such as the gap threshold size or the distance between consecutive gap sizes.
Congestion is detected when a defined number of consecutive gaps (set by consecutive_gaps_for_congestion) meet the criteria for being close enough together, either in absolute terms or relative to a threshold.
Gap Tolerance and Threshold:
The congestion zone logic allows you to define a tolerance (gap_tolerance) for how much the gaps can deviate from a threshold size before they are considered part of a congestion zone. If the gaps stay within this tolerance range, the bars are flagged as being in a congestion zone.
The option use_gap_threshold_size determines whether the script checks the gap sizes against a specific threshold or just the distance between consecutive gaps.
Congestion Zone Types:
The script identifies three types of congestion zones:
Ascending Congestion Zone: All gaps in the zone are ascending (price increases).
Descending Congestion Zone: All gaps are descending (price decreases).
Mixed Congestion Zone: The gaps are a mix of ascending and descending.
The type of congestion zone is determined by checking whether consecutive gaps are all in one direction or a combination of both.
Displaying Congestion Zones:
The script has options to show or hide specific types of congestion zones, such as ascending or descending zones. These are controlled by show_ascending_congestion_zones and show_descending_congestion_zones.
Congestion zones are represented visually on the chart as lines. The color, thickness, and style of these lines can be customized for ascending and descending zones. For mixed zones (if handled), a default color/style can be applied.
Congestion Zone Alerts:
If the criteria for a congestion zone are met, and the user has enabled congestion alerts (enable_congestion_alerts), the script triggers an alert informing the user that the price has entered a congestion zone.
These alerts can be tied to specific types of congestion zones (ascending, descending, or mixed).
Congestion Zone Lines:
When a congestion zone is detected, lines are drawn on the chart to visually represent the zone. These lines extend over the bars where congestion occurs.
The line's color, thickness, and style are determined based on whether the congestion zone is ascending, descending, or mixed, allowing for visual differentiation between the types of congestion zones on the chart.
In essence, the congestion zone logic helps to identify areas on the chart where price movements are tightly clustered, either moving consistently up or down, or fluctuating in both directions. These zones are highlighted with customizable lines and can trigger alerts based on user-defined settings.
