When mapping, the file path and format is are indicated once, and every time a chart is created the program finds the file automatically, converts it into the necessary format based on the preset configuration and displays the data.
<div style="background-color: #E3FBE5;">Since '''MultiCharts 10''' ASCII Mapping file reference details are now visualized displayed under the '''"ASCII Mapping" tab''' in the '''Edit Symbol''' window (see [[https://www.multicharts.com/trading-software/index.php/Setting_Properties#Editing_an_Existing_Symbol_Properties]here]).

To cancel the selection of files for mapping click '''Uncheck All''' option in the lower part of the '''ASCII Mapping''' window.
