The Simplest indicator/expert advisor you will ever code :)

Hi Guys/Girls,

I really need someone to code this simple indicator..

A simple display on the currency chart itself showing whether 1hour, 4hour, daily bar is CURRENTLY up or down using RED or BLUE arrow or box

This will probably be the simplest coding you will write but it is VERY IMPORTANT for me... I am always losing money because I trade against the trend.

Thanks in advance !
