{quote} I do not know of a way to do this directly. Depending on your needs, there are workarounds that might work. For example, try the attached indicator. It will change the chart background (at least visually) depending on the current candle. Red background when close < open. Blue background when close > open. Black background when close = open. There are side effects using this workaround. But it might give you a way of doing what you want. {file} {file}

Hi zznbrm, I like your indicator. Is there a way to programme it so that it only changes colour on the daily candle, irrespective of what timeframe you're currently viewing?

Regards
Kate

Is there any way to change the chart background color based on a variable's value. ie. switch(varValue) { case 0:/*Change chart background color to light red*/ break; case 1:/*Change chart background color to light blue*/ break; case 2:/*Change chart background color to white*/ break; default:/*Change chart background color to white*/ break; }

//| Gets the background color of chart |
//+------------------------------------------------------------------+
color ChartBackColorGet(const long chart_ID=0)
{
//--- prepare the variable to receive the color
long result=clrNONE;
//--- reset the error value
ResetLastError();
//--- receive chart background color
if(!ChartGetInteger(chart_ID,CHART_COLOR_BACKGROUND,0,result))
{
//--- display the error message in Experts journal
Print(__FUNCTION__+", Error Code = ",GetLastError());
}
//--- return the value of the chart property
return((color)result);
}
//+------------------------------------------------------------------+
//| Sets the background color of chart |
//+------------------------------------------------------------------+
bool ChartBackColorSet(const color clr,const long chart_ID=0)
{
//--- reset the error value
ResetLastError();
//--- set the chart background color
if(!ChartSetInteger(chart_ID,CHART_COLOR_BACKGROUND,clr))
{
//--- display the error message in Experts journal
Print(__FUNCTION__+", Error Code = ",GetLastError());
return(false);
}
//--- successful execution
return(true);
}
