It is not possible to change the background color of a RadarScreen cell in the symbol column using TradeStation EasyLanguage. The background color of this column can be set as a property of the RadarScreen settings page but not programmatically. <br /><br />But what if you needed more control over the plot colors, for example, to provide a visual alert? Tutorial 183 demonstrates a way of achieving this by replotting information and then using the SetPlotBGColor keyword to change the background color.<br /><br />Tutorial 183 demonstrates how to:<br />1. Change the color of a complete column<br />2. Change the color of specific cells based on the symbol name or a value<br />3. Make cells flash on and off<br />4. Change the color of cells when they are clicked<br /><br />The tutorial uses the quotes provider, the timer and the RadarScreen host provider (as well as TradeStation RadarScreen).<br /><br />See https://markplex.com/free-tutorials/tutorial-183-controlling-background-color-in-radarscreen-tradestation-easylanguage-tutorials/
