Looking to color code bars based on Ganns swing relations theory.

This looks at just highs and lows of bars and not of closes or opens.

(GREEN) Up bars = higher high and higher low
(RED) Down bars = lower low and lower high
(BLACK) Outside bars = higher high and lower low
(SAME COLOR AS PREVIOUS BAR) Inside bars = lower high and higher low

If anyone knows how to begin programming this inside ninja trader - Would be very greatful for a bit of guidance on how to do it. I'm great with computers but have never coded before so could figure it out quickly if I get a bit of a push first

Cheers
