Hi.
I got this interesting indicator in MT4 but I would like to test it in AmiBroker:

#property indicator_color3 Blue
#property indicator_color4 Blue
#property indicator_color5 DarkGreen
#property indicator_color6 Red
#property indicator_color7 DarkGreen
#property indicator_color8 Red

I tried to convert it myself but it didn't work.
If somebody can please convert it I would appreciate it.
thanks,
Erkan
