Algo, do you need any apprentice. LT
Google or yahoo finance provides daily Open-high-low-close (OHLC) format historic SVXY or XIV trading data.
Using these data, draw a monthly histogram, you can obtain the same result as I posted. This is very useful if there is a strong bias such as today. On opposite, fifty-fifty means no bias, not useful. |
