In this section, you will see how to create a Market Clock, shown here, where we show the duration for which a stock exchange is open. It's a great visual tool to keep track of the opening and closing times of different stock exchanges.
Note
The clock given at http://market24hclock.com/ is a great example of a stock market clock as it quickly gives an idea about the opening and closing times of different exchanges.
The following diagram shows the Market Clock that we will create in this chapter:

The stock market chart that we will build in this chapter has the following requirements:
It should show a 12-hour clock

Each sector should represent the duration for which an exchange is open
The Exchange name should be shown on the sector
Each sector should use a unique color
Based on the preceding requirements, let's start with the design and then we will move on to the implementation...
