Re: reset efs colorbars at midnight...

Steve
One way to do that would be to insert the following lines of code just above main's return statement

PHP Code:


var xTime = fStart.split(":");

if(xTime[0].charAt(0)==0) xTime[0]= xTime[0].charAt(1);

if((hour(0)*100)+minute(0)>=0 && (hour(0)*100)+minute(0)<(xTime[0]+xTime[1])) setPriceBarColor(Color.yellow);

In the logic I first split [at the :] the string that represents the user defined start time. This creates an array of two elements.
Then I create a condition to check if the first character of the first element of the array is a 0 in which case I assign to that element only the second character.
Lastly I create a condition that checks if the time is greater than 0 (ie midnight) and less than the concatenated elements of the array and paint the bars accordingly.
In the screenshot enclosed below you can see the modified script with a start time of 06:30

I was hoping someone could tell me how to modify this efs so that the price bars are colored yellow at midnight, and stay yellow until the next signal (the user defined start time) is generated. Thanks...

Alexis,

Great example of simple manipulation of time. It will go into my sample archives.

Thanks
