Release Notes v9194-v9449
The QuantConnect team has focused on stability and bug fixes in the last two weeks. Diving deep into lingering issues, publishing fixes, and additional regression tests to lock in that stability. We also surpassed 10,000 unit tests giving the platform a rock-solid foundation for expansion!
A few highlights were finally merged into production LEAN. First, we set up continuous integration to generate Python stubs for QCAlgorithm, giving your favorite code editor autocomplete on the QCAlgorithm API. Second, we've rebased, polished, and merged Binance Exchange integration into LEAN and are excited to publish it to QuantConnect in the coming weeks. Finally, we've optimized specific intensive methods to add a 10% speed boost to LEAN.
Special thanks to Github users @mchandschuh @michael-Sena @aarjaneiro @nazbrok @jatinkumar

Another idea for VIX strategy, low DD, high performance..

Hello, I'm tryng to backtest alex meuci strategy until february 2018, because of termination of XIV and I can't. Runtime Error: A data subscription for type 'PythonQuandl' was not found. Also I want to test this strategy but only with VXX. short VXX under 0.95 and long VXX above 1.05. How I should write these code.
Thanks

Just tried to re-run the first algo I posted above (VIX by RSI) - by limiting the backtesting to end of Jan 2018 (i.e. self.SetEndDate(2018,1,20)) - and it did work as before.
Gabriel, why do not you try and use long positions in ZIV (which shorts mid-curve VIX futures, rather than shorting VXX) for a safer and, potentially, easier way to hedge vol spikes with either front VIX futures (now available) or VXX calls?
If I have time will try to post such an example later.

Thanks for the advice, but I want to backtest the system with short VXX because I already have wich ratios VIX/VXX are optimal. How could I change the code to allow short VXX and long VXX. I'm still learning the documentation. Thanks anyway for the advice. Later I will try with ZIV.

RIP XIV and the 1+ billions that vaporated during the liquidation event.
That being said, I am reviving this thread. ;) added my fix on data retrival below (may still have bugs!), some minor refactoring, and lastly, switched XIV to SVXY.

adding another version below. Summary of chages listed below:
+ as suggested by Alex, added "momentum" term based on increasing/decreassing z score of the vix/vxv ratio.
+ logic for long/short volatility is based on if vix/vxv is trending towards contago/backwardation based on "momentum".
+ provided 2 kinds of allocation style - aggressive and conservative.
Backtest performance of the 2 kinds of allocation are listed below (timeframe: 2012 to present).
# aggressive mode: PSR 41%, win/loss rate 59/41, max drawdown 49%, return 1573%
# conservative mode: PSR 34%, win/loss rate 57/43, max drawdown 18%, return 246% (displayed below)
Happy holidays.

Still new to this but learned the hard way to use the Open and not Close from the custom data imported. Lookahead bias is quite powerful! See Open vs Close performance below:

Tried combining momentum indicators along with the vix/vix3m and vix/vix9d ratios as a mesure of contango/backwardation (I've tried the futures term structure ratios but Quantconnect's futures system makes me want to pull my hair out). I use indicators on SPY since I belive it's the "underlying" and more represtative of the underlying market that ultimately affects VIX values, and technical analysis on a actual ETF makes more sense to me.
I used the SPY crossing sma as an exit signal for short volatility, and SPY macd as an exit signal for long volatility. I find that macd tends to "want" to switch every once in a while even when growth is sustained (but not gaining momentum) and provides too many false positives as an exit signal for short vol since the majority of the time the market trends upwards gradually, so I used sma as a kind of trailing exit. However for long vol I find that once the party is over you want to get out quickly before the spike crashes, so I attempt to use SPY macd as measure of momentum and an exit to get out and minimze losses.
Additionally, usually when exiting a long vol position, much of the time the market is recovering even if temporarily, however due to the lingering backwardation this recovery is not always reflected in a short vol ETP such as SVXY, so I take advantage of this period by staying in TQQQ.
If anyone sees something I missed or could improvme, or has thoughts to add it would be much appreciated.

I think you should add 1 day to the Time or set the Period = timedelta(days=1). You might be getting some lookahead bias with the custom data imports. I walk through importing custom data here.
