Price bar charts paint a graphic picture of a stock's price movements both during the day with the 5 minute bars, and longer term with the daily bars. The picture unfolds snowing short and long term supply and demand and how it has moved the stock's price. This helps pinpoint specific areas of buying or selling pressure as they develop.
The bar charts alert you to this „at a glance“ when the bars trade into a tight range that hugs up or down against a certain price (usually the day's current high or low). This consolidation creates a price „compression“ point where pressure builds and is finally released when the price level that held the stock is penetrated. Often this penetration is a the beginning of an intraday trend. By monitoring different stock charts throughout the day, a trader can quickly identify these pattern setups. Since the trader knows which stocks are currently setting up for a potential move, he or she has the edge of catching the beginning of a good trade.
