What the Inside & Outside Bar Indicator (Scanner) Does
The Inside & Outside Bar Indicator automatically identifies two specific price bar patterns — Inside Bar and Outside Bar — and displays them across all monitored assets and timeframes through a structured dashboard.
Inside Bar
A bar whose high-low range falls completely within the high-low range of the preceding bar. This means the current bar represents a narrower price range than the one before it — a structural condition typically associated with consolidation or reduced directional pressure following a prior move.
Outside Bar (Engulfing Bar)
A bar whose high-low range completely contains the high-low range of the preceding bar. The current bar extends beyond both the high and low of the prior bar — a structural condition typically associated with a directional expansion following a period of consolidation.
Both patterns are generally considered more structurally meaningful on timeframes from M30 and above. On lower timeframes, short-term price noise increases the frequency of pattern formation without the structural context that gives these patterns analytical weight.
How to Interpret and Use the Inside & Outside Bar Indicator
The indicator registers a condition when it detects a qualifying Inside or Outside Bar. The directional context of the registered condition is determined by the character of the pattern bar itself — not by a subsequent price move.
When the pattern bar is bullish (close above open), a bullish condition is registered — labeled IBU (Inside Bar Up) or OBU (Outside Bar Up) depending on pattern type.
When the pattern bar is bearish (close below open), a bearish condition is registered — labeled IBD (Inside Bar Down) or OBD (Outside Bar Down).
Chart Markers
Each registered condition is displayed on the chart with three visual elements: a directional marker arrow, a vertical label showing the pattern abbreviation, and a dotted rectangle highlighting the bars that form the pattern.
Arrow thickness indicates pattern type — thin arrows correspond to Outside Bar conditions, thick arrows correspond to Inside Bar conditions. This allows both pattern types to be distinguished at a glance when both are enabled simultaneously.
Timeframe context: Inside and Outside Bar patterns reflect structural relationships between adjacent bars. On timeframes below M30, the frequency of these formations increases significantly due to short-term price noise — reducing the analytical context of each individual pattern. The indicator remains functional on all timeframes, but the structural significance of detected patterns is generally considered higher on M30 and above.
Multi-Asset Monitoring with the Dashboard
The dashboard displays the current detection status across all monitored assets and timeframes in a single structured view.
Each cell shows the pattern type detected (Inside or Outside Bar), the directional context of the registered condition (bullish or bearish), and the number of bars back at which the pattern was detected. Green cells indicate a bullish condition, red cells a bearish one. Color saturation decreases as the condition becomes less recent. Clicking any cell updates the chart to the corresponding asset and timeframe directly.
Indicator Limitations — Inside Bar and Outside Bar patterns are identified based on the structural relationship between adjacent price bars. The indicator detects formations that meet the defined geometric criteria — it does not predict the direction or magnitude of subsequent price movement. Pattern frequency increases on lower timeframes due to noise, reducing the structural context of individual detections. All registered conditions should be evaluated within a broader analytical framework that considers overall market structure and context.
