MQL4参考 MQL5 特色 MQL5 functions Chart Operations

Chart Operations

Functions for setting chart properties (ChartSetInteger, ChartSetDouble, ChartSetString) are asynchronous and are used for sending update commands to a chart. If these functions are executed successfully, the command is included in the common queue of the chart events. Chart property changes are implemented along with handling of the events queue of this chart.
