The system is 100% automatic, there's no discretionary decision.

Unfortunately not.

I use a system that trades at the NYSE's stock market close. As I'm living in Asia, that involves having a quite shitty schedule. So I wonder if there's any way to do it automatically. My system is based on the following information: the two nearest futures's prices of a particular product, the...

Are you sure you wouldn't be taxed for trading earnings in Singapore if they are your main source of income? I know capital gains taxes are in theory 0%, but in practice in some countries things change if they consider you an active trader and bullshit like that. I'm currently living in the...

Actually, as margin requirements for short positions on VIX futures, VXX and UVXY are so high, I just simply go long SVXY (I wish Proshares hadn't changed it from -1 to -0.5...).

What does that mean in practice, could you give me an example? How do you hedge a VXX short by being long volatility if it isn’t by buying VXX calls? Do you buy VIX futures (that would be absurd, it would be better to just short futures directy instead of VXX)?

Excuse my ignorance, but what do you mean with “hard deltas”? The problem of using short ES as a hedge is that the futures “beta” keeps changing, and in some cases even becomes positively correlated to VIX futures. I try to find something safer, like simply VXX calls when shorting that ETF or...

What would be an effective way to hedge a short VXX position? I have been studying this (and UVXY) for years but I can’t find any strategy with them that would give decent returns while being hedged. Calls for both ETF are always very expensive. Puts too.

Will it be possible to go long, though? I wonder when will futures options be offered.

I actually calculated something like that. The only problem is that I know historical VIX values, but the VIX doesn't tell me the IV of a particular option, but of a group of options. And in practice I don't sell so many different options (for many reasons), but just those near the ATM. And...

The problem is finding bets with positive expected value. If you want to randomly bet for unlikely scenarios, you can just buy literal lottery tickets.

I'm asking about the SP500, not SPY...

I see, thanks. But I'm looking for older data. As you say, if I wanted information from 1993 I could just download it from Yahoo.

Thank you. I'm not familiarized with Quandl, so it's a bit confusing, it seems like I have to download an add-in for excel or something like that. From which years does it provide the kind of information that I'm looking for?

I'm looking for daily historical data (adjusted close price is enough) of the SP500 including dividends. Something like this but including dividends: http://finance.yahoo.com/q/hp?s=^GSPC+Historical+Prices Could anyone help me? I know I could just download the SPY data (from 1993), or from CBOE...

I see, Taleb precisely was talking about currencies. "But if you have a 24-sigma event on an option that’s 24 standard deviations out of the money, your payoff is 750,000 times your bet, which is what happened in eurodollars." Let's say you want to bet for example that the HKD will no longer...

Why would all money in circulation disappear if the US government doesn't pay its debts? We could be betting in a different currency anyway, as I said. And to make the bets, we would need to deposit the money at the bookmaker before. Sorry for the heavy derailing, I should had simply started a...

The same party that would enforce any other payment. Both of us would need to deposit our money in advance in the bookmaker or similar.

In this exact case, betting against the government paying its debts, maybe there would be no payoff in the financial markets, but a bet could be made outside. For example, we can make the bet, if you really think it's completely risk-free, you would ask me for very small odds. And if I find...

You could bet in a currency different than USD that the government will default . It may be more complicated to find a counterparty, but it's a possible bet. When lending money to another party, the best possible scenario is that they return it to you (plus interest), but nothing better can...
