Cummulative rsi calculation

[ShruggedAtlas]

I'm trying to do something rather simple and it's just not working - My indicator comes up blank on the chart. What am I doing wrong? the code I came up with is a simple summation of a two period RSI for the last three bars. I don't see how it could be simpler! The plot just comes up with nothing calculated. I've saved and compiled. Any help on this would be greatly appreciated.


protected override void OnBarUpdate()
{
//CALCULATE THE 2 PERIOD SUMMED RSI

double CUMRSI = RSI(2,3)[0] + RSI(2,3)[1] + RSI(2,3)[2];

Plot0.Set(CUMRSI);
}

Note: Today is my first day using NT - so be easy on me

Hi ShruggedAtlas,

It is always a good idea (in my opinion) to name your plots.

In the Initialize() you need to have something like:
Add(new Plot(Color.Cyan, PlotStyle.Line, "CumRSI"));

In OnBarUpdate() you set the value:
CumRSI.Set(...);

In the properties you need to get the values you calculate.The following should work for you.

[Browsable(false)] // this line prevents the data series from being displayed in the indicator properties dialog, do not remove
[XmlIgnore()] // this line ensures that the indicator can be saved/recovered as part of a chart template, do not remove
public DataSeries CumRSI
{
get { return Value[0]; }
}

If you have more than one plot chnage return Value[0]; to return Values[0];

I hope this gets you going. :-)

Hi ShruggedAtlas,

If you apply indexing to values but do not see a plot, check the log tab of control center for any error messages. It's likely you're running into this issue:

You can resolve by preventing bar processing for the first 3 bars.
if (CurrentBar < 2) return;

You can also consider using built in method SUM(), which accepts series as input.

Plot0.Set(SUM(RSI(2,3), 3)[0]);

problem solved!

Thanks RyanM! It turned out that it was in fact the problem you suggested. I checked the log and did indeed find error alerts notifying me of the problem. The code checking for current bar position was added and it fixed the problem. Also, the SUM function definitely shortens my code up a bit. Thx!

Also thanks to Zeos6 for giving me some practical tips to make my code a bit more readable. I did name my plot as you suggested and it makes the code more understandable.

Thx guys!
