Inside bar for Heiken Ashi

Hey there, I am new to the whole ninjascript thing but I am looking to add an indicator to my Heiken Ashi bars. I would like the bar to change color if it is an inside bar, the high of the current bar is lower than the high of the previous bar and the low of the current bar is higher than the low of the previous bar.

Also I would like the same indication if the body of the current bar is inside the body of the previous bar regardless of the highs and lows.

It sems like it should be pretty simple to work out but I dont see how to input these values in the indicator wizard without typing out the code.

Has anyone seen something like this out there?

Thanks
