Hi, I saw the previous question about RVI and that was solved using C#. Is there anything in the works for putting RVI either as an indicator straight on QuantConnect or on Github? Struggling to try and transfer from C# to Python. Thanks

Hi Erik,
The Relative Vigor Index has been merged. I've shown an example of RVI in the attached backtest.
Best,

Thanks for the help. Is it possible to add the RVI Signal line as well? I tried to add one with a crossover as the buy/sell and unable to get it to work. Doesn't like the RVISignal Function.
class TransdimensionalVerticalAntennaArray(QCAlgorithm): def Initialize(self): self.SetStartDate(2020, 1, 19) # Set Start Date self.SetEndDate(2020, 1, 30) self.SetCash(100000) # Set Strategy Cash self.AddEquity("SPY", Resolution.Hour).Symbol self.rvi = self.RVI('SPY', 14, Resolution.Hour) self.rvi.Updated += self.RviUpdated self.rviWin = RollingWindow[IndicatorDataPoint](3) self.AutomaticIndicatorWarmUp = True def RviUpdated(self, sender, updated): '''Adds updated values to rolling window''' self.rviWin.Add(updated) def OnData(self, data): # Wait for windows to be ready. if not self.rviWin.IsReady: return currRVI = self.rviWin[0] i = self.rviWin[self.rviWin.Count-1] j = self.rviWin[self.rviWin.Count-2] k = self.rviWin[self.rviWin.Count-3] RVISignal = (currRVI + (2*i.Value) + (2*j.Value) + k.Value)/6 if currRVI.Value > RVISignal: self.SetHoldings("SPY", 1) elif currRVI.Value < RVISignal: self.Liquidate("SPY") else: returnÂ

The RVI signal should be accessible by accessing self.rvi.Signal. It is automatically created when creating a new RVI indicator

Erik schuh,
Here is the one with the crossover

Thanks Aaron. Seems to be working until around July 2020 and then the rvi and signal gert all screwed up. Any idea why that is?
Also anyone know if the source code be put up on GitHub? I want to see the equations behind the indicators and make some adjustments.

Hi Erik,
The custom plots look strange at the end of the backtest because custom charts are limited to 4000 data points. See these docs for reference.
The source code for the indicators are available on our GitHub repo.
Best,
Derek Melchin
