Color-coded stochastic study not aaplying to new bars

[pghostine]

Hi,

I wrote the EFS code displayed below. Basically, I'm plotting %D and %K inside a study window, and I'm drawing %D in red when it's sloping down, and in green when it's sloping up. When I load the study, it color-codes all the previous bars exactly as expected. However, when new bars are received, they're drawn in red regardless of the slope direction. I just can't figure out what I'm doing wrong. Help!!!

Nevermind, I found my bug!!!
