Inside bars can be useful in several cases:
1 - If you trade using the inside bar strategy. I won’t go into detail about this here, as you can easily find numerous descriptions of this strategy, as well as videos explaining how to use such bars. With this indicator, it will be much easier for you to spot these bars on the chart, no matter what scale you’re using.
2 - If you trade using smart money concepts. Highlighted inside bars will help you avoid mistakes when defining structure (highs and lows), as such bars should not be marked as structural points.
Additionally, if you use automated scripts for strategy-based trading, my script triggers an alert the moment an inside bar appears, which you can process as needed.
