setBarBgColor on Previous High/Low

[CAS1]

Sorry if this has been done somewhere...I'm searching for this right now in the past messages. But, what I am trying to do is create an EFS that colors the bar background green when the current bar is equal to or greater than the previous days high, or red when the current bar is equal to or less than the previous days low. If the current price is inbetween the previous high and low, then it would just leave the background as the default chart background. Any help would be appreciated.

Thanks,

In your script you will need to specify what you mean with "current bar is equal to or greater/lower..." in other words is it the Close or the High/Low of the current bar that need to be higher/lower than the prior day's High/Low?
Anyhow the example below shows you how you would set up the conditions assuming that by "current bar" you mean the Close. Replace close(0) with high(0) or low(0) where necessary.
For information on the inv() function I used in the example see the EFS2 Function Reference-> Series Functions in the EFS KnowledgeBase

Thanks Alex...with that input I was able to use the Wizard and generate an EFS that works great.
