At times it takes some time to get an order filled or a stop-loss order does not work immediately. Because I trade very light, I did not have problems with the low volume on both instruments.

For reference, I just re-performed the comparison of the nine S&P sub-components. These back tests are performed without stop-loss, without possible optimization (only trade under certain 20DMF states) and using only the single ETFs from July 30, 2007 up until the close of yesterday.

PDP,


Until 2009, the composition of these XLX was much different than what we have since 2010.
Hence, the XLX model that I ran in back-tests is reliable only since 2010.
There is no point in going back down to 2007.
