Strategy: Combo Z Score
Updated
Strategy version of Combo Z Score
Objective:
Can we use both VIX and MOVE relationships to indicate movement in the SPY? VIX (forward contract on SPY options) correlations are quite common as forward indicators however MOVE (forward contract on bonds) also provides a slightly different level of insight
Using the Z-Score of VIX vs VVIX and MOVE vs inverted VIX (there is no M of Move so we use inverted Vix as a proxy) we get some helpful indications of potential future moves. Added %B to give us some exposure to momentum. Toggle VIX or MOVE.
If anyone has a better idea of inverted Vix to proxy forward interest in MOVE let me know.
Noticeable delta is that Vix only approach over the back test period is slightly better. Questions would be, what is the structure and nature of the market over the test period and in a bear market would MOVE or combined perform better.

Release Notes
Added closing of trades ie when selling (shorting) close all long positions and vice versaRelease Notes
Add capability to set your own start period. This will help if you want to test say a bullish market (2010 -> now) or expand to longer timeframes. Would it help to add an end date for those that want to choose specific date range?Release Notes
Added option to apply an EMA on shorts ie only short if close is below ema. Ran this through Python with some different EMA values and 100 appears most reliable. CAUTION: Use normal candles not hiken ashi as you will get different results. Also, I ran this through a Python Backtester (Backtesting.py) and got woeful results so be cautious. Having said that I also ran it in 'dumb' mode essentially mimicing buy sell on long and short which was profitable with 100 lots (allowing for time to see event trigger and placing position the following day). Slippage and broker fees need to be considered as well. I also ran a model with OBV + OBV MA in Python and it under performed simple EMARelease Notes
Added Oil over Oil Volatility as a selectable option. Oil by itself out performs as an indicator over long timeframes. I also ran this in a Python script I built to validate the return profile using CL=F (due to yfinance not having USOIL as a ticker). Excluding the EMA (which matters for this script) you get a return of 72.8 however note the volatility on the combined scenario. Essentially it validates the script will be profitable. Better than buy and hold? Not sure.Long Results for SPY going back to 0, Sample size: 24 trades
