Quote from gmst:
Your post caught my attention because I trade futures and I trade less number of contracts in times of high volatility to get same risk per trade. However, your peak exposure in shares during 2008 was 5-10 times the peak exposure in 2012. VIX(2008) was 3-5 times VIX(2012). So, if you are sizing your positions by volatility, for every 300-500 shares a clip in 2012, you would trade 100 shares a clip in 2008. Correct?
So, to attain a peak share exposure of 5 to 10 times in 2008 Vs 2012, you would be trading (5 to 10) multiplied by (3 to 5) = (15 to 50) times number of trades in 2008 Vs 2012. That means a 3 to 5 times higher VIX in 2008 led to 15 to 50 times more number of open signals/trades in 2008 compared to what you get in 2012 at the peak exposure time during the day.
Do my numbers make sense? If not, please feel free to correct me. I started trading after 2008 and so have no experience of trading in those extreme conditions. I want to prepare myself though, in case such extreme market conditions return in future. So, I am very interested in learning from your experience. Appreciate your thoughts.
