For every 15 minutes (or other internal) only the close is recorded on the chart, and then each close is linked to each other creating a continuous line. The drawback is that you may not be trading with all the information you need. If the bar is green it means the last price in that 15 minute period was higher than the price at the start of the 15 minutes. If the bar is red, it means the last price is lower than the first.
