A simple, yet untradable (unstable), VIX Strategy using two ETFs.
It has a simple binary (all or nothing) allocation:
1. long vol (buy VXX),
2. short vol (buy XIV),
3. none.
Signal is just the standard RSI but used as a momentum (rather than a contrarian) indicator. Levels are also those standard to indicate overbought or oversold securities (i.e. 85, 70, 30, 15).
Strategy is, however, a pie in the sky... a simple daily VIX/VXV ratio signal still more stable/reliable.

Hi .ekz.,
Users interested in metrics not supported by web QC can save the portfolio values and do custom calculations in OnEndOfAlgorithm and print the results or retrieve the results of the algorithm as shown in this post.
I've shown how to the former method in the attached backtest.

Is the PSR calculated using CSCV?

Longer duration backtests have higher PSRs. Is there a standardized time period for making sure an alpha has >= 80% PSR before submitting?

Hi Jake,
No cross validation is used in the calculation. The formula is available in the notebook at the top of this thread. Implemented in Python, it is:
def get_psr(self, benchmark = 0): skew = sps.skew(self.returns) kurtosis = sps.kurtosis(self.returns) n = len(self.returns) estimate_std = np.sqrt( (1 - (skew*self.sharpe_ratio) + ((kurtosis-1)/4)*self.sharpe_ratio) / (n - 1) ) return round(sps.norm.cdf((self.sharpe_ratio - benchmark)/estimate_std),3)

Hi Abhijeet,
When submitting an alpha for Alpha Streams, the strategy must be backtest over the most recent 5 years. Refer to our documentation here.
