Here is what I have so far but I would like to draw an X or some sort of marker when the price crosses below or above the MA - anyone got an example I could work off?

If you want to draw text on a chart, Chart.DrawText is your friend:

Example:

Chart.DrawText("X text", "X", MarketSeries.Close.Count - 1, Symbol.Bid, Color.Goldenrod);

You can also search for examples:

Not text - I want to draw a shape ("X" for example) on the candlestick when the price crosses over Hull MA.

Then you have to draw lines. But you'll have to decide how far you want the lines to extend, and how steep ofan angle to form the "x". For instance, you might have to draw one line with the coordinates (x-2, priceCrossPoint + 2) and (x+2, priceCrossPoint - 2). That will draw from top left to bottom right. You'll have to do the same for the other leg.

The DrawText approach is a lot simpler to get started so you can see if you like how it's working. Then from there I would graduate to drawing the lines to form the X.

I know you want to draw an x but using DrawText has the advantage of being simpler and also has horizontal and vertical alignment. You can also us unicode characters to get a proper cross. Just use \u2716 as the text string for example. more example unicode crosses here - https://en.m.wikipedia.org/wiki/X_mark

Maybe this will help you

Chart.DrawIcon("uniqueIconName", ChartIconType.Star, barIndex, yPrice, Color.White);

You can draw an “X” easily with two arrows. Or just use an arrow by itself.

Just a quick example:

var yPosition = Bars.MedianPrices[index];
IndicatorArea.DrawArrow("XFirstHalf" + index, index, yPosition + Symbol.PipSize, index, yPosition, Color.Red, 2);
IndicatorArea.DrawArrow("XSecondHalf" + index, index, yPosition - Symbol.PipSize, index, yPosition, Color.Red, 2);
