Using a Close Price Chart, the thickness of the curve represents the spread.

Thus:

• The upper boundary of the curve represents the ask price.
• The lower boundary of the curve represents the bid price.

Note that the thickness of the curve is not fixed, as spreads vary depending on market conditions.

Because this curve only shows the closing price of each interval, it does not show the full range of prices that may have been active during the interval. Hence, it is possible that a Buy or Sell indicator () will be positioned so that it is adjacent to the curve.

The segment at the very end of the curve is depicted in a lighter shade of blue. Whatever granularity you choose, this area is updated every 5 seconds to correspond to the latest incoming rate.

If the mouse is positioned over the curve, then a “Graph Information Box” appears which lists the closing bid and the ask price for the interval represented by the location of the mouse.
