GetSymbol ();
Description
Returns the currently selected symbol.
When used on a futures chart, GetSymbol() returns the corresponding futures symbol with a namespace appended. Namespace is a market identifier code*.
Consider an /ES chart. To find this symbol’s namespace use AddLabel():
AddLabel(yes, GetSymbol());
The function displays /ES:XCME, where XCME is a namespace reserved for the Chicago Mercantile Exchange.
To avoid unexpected results, use namespaces in string comparisons:
AddLabel(GetSymbol() == "/ES:XCME", "Chart for /ES!");
Example
declare lower;
plot Diff = close(GetSymbol()) - close("IBM");
This example script plots the difference between Close prices of currently selected symbol and IBM.
*A namespace, or market identifier code (MIC), is a four-letter code assigned by the International Organization for Standardization (ISO) that uniquely identifies trading exchanges and markets, facilitating automated trade processing.
