Mouse over the chart's x-pivot (date/time) and drag or slide left and right. This activity will zoom in and out so you can coordinate your preferred period splendidly. For a one-day exchange, draw two level lines over the most recent 24 hours of development. The top line should demonstrate the most grounded price of the day, the last one should demonstrate the weakest. Now you have a range of development for more than 24 hours. This is your base range. The price can, obviously, far surpass the base range, yet this, for the most part, happens due to a news release.
