Wips occur with all systems as near as I can tell. 5% loses are hard, 6% harder, etc. No system is perfect for all situations and all ETFs.
I've not traded FAS this mid year, too volatile, when there are better ETFs available, e.g., TNA. Generally, when volatility rises I use shorter time frame charts, or simply step aside and don't trade.
It's always important to pick ETFs that are amenable to one's system; I've used my daily system with TNA, SSO, and VTI. Chart reviews indicate it will work with other ETFs.
Until it doesn't. . .then it's time to change what I'm doing.
