Cracking the Swing Code

[Richard Von]

As I try to learn to code indicators I am examining the code of the standard "Swing" indicator - which marks lines at high and low price pivots. I can't figure out where in the code the values are plotted.

Ultimately, I hope to be able to add a diamond above or below the actual pivot point ( and still leave the trail of dots as is).

Any guidance would be appreciated.

Hi Richard,

The Swing indicator is one of the more advanced indicators in terms of programming code.

What I can tell you is that plot values are stored in the SwingHighPlot and SwingLowPlot DataSeries objects. Wherever you see a .Set() method called is where a value is being stored to the DataSeries and wherever you see a .Reset() is where a value that may have been previously stored is being removed resulting in "no plot" at that bar visually.

I think that its quite similar to the to the Scalper indicator in the shared section, in that it doesn't know the swing bar until a couple of bars later, so it overrides the Plot class to add them after the fact.

Also interesting adding them both on the same chart as they agree half the time.

Hi Richard did you ever succeed in figuring out this indicator of yours that you described? I'm very interested in it. Please let me know because I've been trying to build one myself as well.
