Hopefully the story of TVIX CHIT and its defeat at the hands of his commanding officers, Credit Suisse, (also known a CHIT SUISSE) gives you some insight for the following recommendation.
Avoid TVIX. Use 'real' Volatility ETFs instead, not FAKE ONES WITH NAMES THAT MISLEAD and MATERIALLY OMIT FACTS.
Trading volatility is difficult enough. Don't bother yourself with concerns over whether Credit Suisse thuggs will add uncontrollable variables to your trade by messing with TVIX so that they can gain fee income. If you are already long TVIX, look to DUMP THE CHIT on strength and switch over to a more predictable product.
Put your money on a product that does not depend on Credit Suisse's business model of ripping-off somebody everyday to generate fee income. DUMP TVIX CHIT!
