Vix Offers on Platform

Question

Hi both,

Can you please clarify what the Volititily index tracks on the platform. 

I see DFB, Mar and Apr offers. Does the March track the March 19 future, the Apr track the Apr19 future? What does the DFB track?

or do they all track the same future? If so how is this decided is there a date to expiration that you use to then roll to the next contract?

Regards
Danny

Mar and Apr will follow their respective Mar19 and Apr19 contracts. The DFB will be priced using our standard undated commodities method, and as a result will not attempt to mirror the cash VIX.

The price will be between the two front month futures contracts, as with all our other undated commodities, and will allow continuous charting with no expiry or rollovers.

As an example

I have only just noticed the dfb version of the Volatility Index.

The description you have of the dfb is that it seems to operate like the etf VXX?

VXX is notorious for decay because as the month progresses one has to typically sell at a higher future and replace with a closer, lower one each day.

The chart of the ig index dfb does not seem to indicate strong decay. Is that just a trick of the chart or do you have some special calculation that stops it? e.g. such as not gifting the proceeds of decay to those who may want to short the Volatility dfb? 

Is there any documentation I can peruse so that I can understand exactly how it works?

Thankyou for that. It pretty much replicates the answer posted by JamesIG earlier in this thread. What it doesn't answer is why doesn't it seem to decay like VXX as the month progresses and the futures curve is in contango.

They both purport to operate in the same way by buying and selling 2 front month futures contracts on a daily basis during the course of a month. I attach charts of Vxx and IG's Volatility Index and you can see how vxx decays over time yet Volatility index does not seem to.  What I would like to understand is what is the difference between them.

I see what you mean, don't know what IG's "standard undated method" is and though doesn't attempt to "mirror  the cash VIX" there must be some reference to the underlying market within the model (see chart below).

    • Some excuse is needed for a pullback ...
    • The spike down in indices in the last hour was the same ol' trade war news, China stating they are less optimistic than the US and feel they have been mislead by recent talks where they felt they had agreement over a rollback of tariffs that the US now say is not the case. After 18 months of this you should be use to it by now. 
    • Dax, Nikkei and FTSE100 remain below recent (past 2 weeks) turning points and we have seen an interesting recent bearish candle in play on US large caps, a potential spike and retrace back down, which could signal rally exhaustion.  In the case of the Dow and Nasdaq this occurred with an overshoot of the 4H chart rally channel and in the case of the Nasdaq also the Daily and Monthly long term resistance trend lines (overshoot and quick retrace being a particular signal of an exhaustion phase).  In the case of the SP500 this has occurred with a hit right on the Daily resistance trend line and rejection, so far at least.  As I have mentioned before: with volume relatively weak and seemingly in a down trend; and with COT net long positions weak and weakening (not what one would expect of a breakout rally); and with Gold/Silver rallying; and with NMD at the turn points on all markets and as USDJPY has also taken a similar bearish hit; the odds of a bearish phase are good and the risk reward is decent. I am already Short Dax and FTSE100 off the previous turns but money where my mouth is this time on SP500, as the exposure is tiny, I am Short off the hit and turn on the daily trend line with tight stops just above.
