Conditional Change High and Low

static int LastDirection = 0;

if( you want to draw an UP ){

if(LastDirection == -1 || LastDirection == 0){

draw up arrow;

LastDirection = 1;

}

}

if( you want to draw a DOWN ){

if(LastDirection == 1 || LastDirection == 0){

draw down arrow;

LastDirection = -1;

}

}

Hi, thanks for your reply.

I've included the code for the indicator below. Would you be able to make amendments accordingly?
