Value outside of range - divide by zero issue

[ShruggedAtlas]

I've got a simple indicator that compares the relative changes in price to changes in another oscillator. I've printed the resulting data to the output window and the values vary from negative to positive and are in a relatively tight range except when there is no change in price and I end up with a spike to infinity (which prints to the output window) this seems to occurr because when price doesn't change there is a divide by zero incident.

Is there a way to check for divide by zero and not plot that? or is there another approach I should take to compare the relative changes of two sets of data?

Here is my code:

			double RsiDelta = (RSI(2,3)[0] + RSI(2,3)[1] + RSI(2,3)[2]) - 
								(RSI(2,3)[1] + RSI(2,3)[2] + RSI(2,3)[3]);
			
			double PriceDelta = (Close[0] - Close[1]) * 100;
			
			Print("RsiDelta is " + RsiDelta);
			Print("PriceDelta is " + PriceDelta);
			Print("RsiDelta divided by PriceDelta is " + RsiDelta / PriceDelta);

            PTR.Set(RsiDelta / PriceDelta);

ShruggedAtlas,

double PriceDelta = (Close[0] - Close[1]) * 100;

and

PTR.Set(RsiDelta / PriceDelta);

Is the culprit here. This may be zero, as such you need to check :

if ( PriceDelta < Double.Epsilon )
{
//do something
}

You may want to use the prior PriceDelta that wasn't zero, i.e. keep track of the previous PriceDelta and only update the previous one if PriceDelta isn't zero.

Please let me know if I may assist further.
