Chart Operations
Chart Operations
These are functions for working with charts. All chart operations are allowed in Expert Advisors and scripts only.
The functions defining the chart properties are actually used for sending change commands to the chart. If these functions are executed successfully, the command is included in the common queue of the chart events. The changes are implemented to the chart when handling the queue of the chart events.
Thus, do not expect an immediate visual update of the chart after calling these functions. Generally, the chart is updated automatically by the terminal following the change events - a new quote arrival, resizing the chart window, etc. Use ChartRedraw() function to forcefully update the chart.
