Circles-and-whiskers only display circles

The circles-and-whiskers are a tool in the Hurst Cycles indicator for MT4. The circles represent the exact time at which a trough or peak of a particular cycle is expected to form in the market, the lines on either side (the "whiskers") represent the range of time in which that trough or peak could reasonably be expected to form.

There is a setting in MetaTrader 4 that prevents the whiskers from being displayed.

To solve this issue:

1. Right-click on the chart and click on Properties.
2. Navigate to the Color tab.
3. Make sure that the Background is not set to None. Any color can be chosen to avoid this problem.
