The close on the 5-minute bar gives insight into the immediate market direction of trend for a stock. When a stock closes at the low or high of the 5-minute bar, there is often a short-term breather where the stock will go in the opposite direction.

This breather can mark a major reversal, but in the majority of cases, it creates the environment for a .25% - .5% counter move.
In the morning stocks will trend hard for the first 20-30 minutes into the 10am reversal time zone. Day traders that are looking to go opposite to the trend can wait for a close at the high or low of the 5 minute bar to go opposite to the morning move.

Even if you are not trading 5 minute charts, it is essential that you keep an eye on them. The majority of day traders are using 5 minute bars to make their trading decisions. Therefore, these traders tend to control the action. If you are a trading with the 15 minute charts, be mindful that a sharp countertrend move can occur at the close of a 5 minute bar.
Remember, a close at the high or low of a 5-minute bar is a potential indication that a minor reversal is in play. Day traders should not immediately exit their winning position, but should rather look at this as a sign of a potential trend change.
