These types of strategies are suitable only for those with direct access to a prime broker that offers low cost execution and liquidity search algos that minimize slippage. These are not strategies for retail traders because they try to exploit small idiosyncratic edges. There are a number of significant steps to convert the idea to an automated strategy that often involve hundreds or even thousands of lines of code depending on specifications.
The strategy matched SPY buy and hold return but at much lower drawdown. Sharpe for the strategy is close to 1 versus below 0.5 for buy and hold. The trade sample is very large and impact of friction high, therefore performance is sensitive to execution cost. In 2008 return was about +10% versus -36% for buy and hold. Return was also positive during 2011 and 2018 corrections. There is no losing year since 2008.
