candlestick pattern signal: accuracy

Dear Spotware

I am trying to get a candlestick pattern signal more accurate.
Is it correct to use the following parameter:

[Parameter("PipSize", DefaultValue = 1E-05)]
        public double PipSize { get; set; }

and where do I integrate this parameter into the DrawText function to generate the signal?

ChartObjects.DrawText("BearishEngulfing" + index, downText, index, high, VerticalAlignment.Top, HorizontalAlignment.Center, Colors.Red);

(I use the Last method of DataSeries class to access current and previous values)
