A Gold Pass member asked the following question based on a situation where he was using the Global Dictionary to share information between two charts (chart A and chart B): “If I disable the indicator in chart A, its last computed amount remains in the global dictionary and the indicator in chart B continues plotting that last computed value. How can I communicate to chart B when an indicator is disabled or removed on chart A?
Quick-Tip 45 uses two programs, a sending program (on Chart A) and a receiving program (on Chart B):
- the sending program: _QuickTip45-Send
- the receiving program: _QuickTip45-Receive
The sending program stores two moving averages in a Global Dictionary. The receiving program reads the information from the Global Dictionary and plots it. If the sending program’s status is set to ‘off’ the receiving program continues to plot the last value.
This quick tip demonstrates how the sending program can communicate to the receiving program when it is un-initialized. The un-initialize event is used to change a value (“OnOff”) in the Global Dictionary to 0. This value is read by the receiving program. Watch the following video to understand the EasyLanguage syntax.
