An
inside bar is a bar which is completely within the range of the preceding bar,
i.e. it has a higher low and lower high than the bar immediately before it.
An inside bar indicates a time of indecision or consolidation. On a smaller
time frame it will look like a triangle. Inside bars often occur at tops and
bottoms, in continuation flags, and at key decision points like major support/resistance
levels and consolidation breakouts. They often provide a low-risk place to enter
a trade or a logical exit point. In the graphic the yellow bars are inside bars
(S&P500 futures 5-minute bars). If you notice, one of the yellow bars does
not have a higher low than the previous bar as in the definition above. Some
traders use a more lenient definition of inside bars to include equal bars.
