Price Levels: From a Line on a Chart to a Data Object
A discretionary trader can say “there is a strong level here.” Software needs more: a price, tolerance, origin, age, number of reactions and a precise invalidation rule.
Levels are areas of decision
Treating every level as a single exact tick is often too rigid. A configurable tolerance can represent the zone in which the system evaluates rejection, breakout or false-break behavior.
Build from meaningful extremes
Start from significant highs/lows and locations that preceded meaningful displacement. Higher-timeframe structure can provide the context; local structure can refine execution.
Store level metadata
A useful level object can contain price, timeframe, creation time, touch count, penetration depth, last reaction and status. That makes the concept testable instead of decorative.
Implementation checklist
Automation principle: every visual concept should have explicit inputs, thresholds, states and an invalidation rule before it becomes trading code.
