I have learned that this will work as well;

if(iOpen(NULL,0,1)<iOpen(NULL,0,2) && iOpen(NULL,0,2)>=iClose(NULL,0,2)) siCurrentDirection = 1; //up
if(iOpen(NULL,0,1)>iOpen(NULL,0,2) && iOpen(NULL,0,2)<=iClose(NULL,0,2)) siCurrentDirection = 2; //down

A little shorter than the first I made.

I believe I can use the "TimeFrame" standard constant inside these to get
data from other time frames. But, this will work for now.

Have a great day Everyone!!
