Understand the trigger
What is Double Inside Bar?
The Double Inside Bar alert looks for a current candle whose high-to-low range is smaller than and inside the previous candle, while that previous candle is also smaller than its predecessor. It surfaces consecutive range contraction rather than a move through a level. ChartsWatcher offers five-minute, fifteen-minute, thirty-minute, sixty-minute, four-hour, and daily options, with calculations across regular and extended-hours sessions.
An illustrative example
Double Inside Bar in practice
Imagine three hypothetical candles with progressively narrower ranges: $24–$25, then $24.20–$24.80, then $24.35–$24.60. This nested sequence illustrates the contraction the alert brings into view. The relevant observation is the relationship between the ranges, regardless of whether the final candle’s body closes red or green.
Make it part of your workflow
Catch the event. Keep the context.
Use ChartsWatcher to gather stocks with increasingly contained candle ranges for chart inspection. Compare the formation with the wider session range and nearby recent highs or lows. This provides a focused view of compression before you separately monitor any later movement outside it, rather than treating the compression itself as a breakout.
ChartsWatcher brings your chosen alert types and filters into the same alert window. Add the data columns you want to see, then use the connected chart and news tools to explore a matching symbol.

What should I check before using this alert?
Consecutive contraction does not predict which side price will leave next. The help text requires the prior candle to be smaller, without publishing additional numerical detection tolerances.
