Coding Help Please

[eggzactly]

Hi,

 

can some excellent coders here help me in this task :

 

i want to define trend based on the ma_in_color indicator. This indicator have 3 colors, blue - up | red - down | mid - yellow.

 

The really help i need is the ea defines the trend only based on blue and red colours, for instance if we are in blue - uptrend and then appears a yellow, the ea consider this yellow up trend until appears the red color - opposite applies.

 

thanks in advance.

 

regards,

 

eggzactly

Bumping this one, really need your help please...

Just saw this--you probably have this figured out by now, but if not ping me.

Hi eggzactly

 

Good day and Happy New year,

 

so you want to build an EA based on Blue and Red color only, right??

 

you would assume that the yellow one is also up,...

 

Ok, I think I got it....

 

I will look at it and let you know whenever I can,

 

Best wishes,
