Unexpected results from script

I set up a DrawPoint when CrossAbove(macd.Diff, 0, 20) is true.
I'm getting plots where the Diff isn't above 0.

I have set up : MACD macd = MACD(Close, 6, 12, 9);

I added the standard MACD 6,12,9 indicator to check results

CrossAbove(IDataSeries series1, double value, int lookBackPeriod)

CrossAbove(macd.Diff, 0, 20) is true

Did you intend for the statement to evaluate to true if the macd.diff was above 0 at any time in the last 20 bars?

If you're looking for a marker on the bar that it crosses 0 on then you want the look back period to 1 I believe, possibly 0, I'd have to check.

I intended to check for a cross of the diff over 0 over the past 20 bars, and if so draw a dot.

if (CrossAbove(MACD(12,26,9).Diff, 0, 20))
DrawDot("myDot" + CurrentBar, false, 0, Low[0] - 1 * TickSize, Color.Blue);


Then this code is correct, but you have to consider it will then of course also draw a dot if the current diff is < 0 because the diff 15 bars back might still be > 0.

For a dot on a cross of the 0 try this -


if (CrossAbove(MACD(12,26,9).Diff, 0, 1))
DrawDot("myDot" + CurrentBar, false, 0, Low[0] - 1 * TickSize, Color.Blue);
