Trying to code an EA from an Indicator

Trying code an EA but not sure how to retrieve GMTS Tape Value

I got this EA from Cody of Genesis Matrix .. this is a tape indicator

I was wondering how do i get the current bar color and previous bar color

e.g if now is bullish ,it show "blue" and bearish it show "red" or grey for no action.

how do i get the color state into a variable..

You can use like this
double iCustom(
string symbol, int timeframe, string name, ...,int mode, int shift)

In that int mode 0 means Blue and int mode 1 means Red.
