Our study was conducted in the 6 sector ETFs mentioned above using data from 2005 to the present. We chose the option cycle closest to 45 . We sold at-the-money (ATM) short and , if possible, or held to expiration if we could not. A results table on the sector ETF short Straddles was displayed. The table included the win rate, average P/L, average win and average loss. The table showed that all the ETfs had similar win rates but different P/Ls due the the variation in underlying prices.
Within the Okataina Volcanic Centre, heat flow from the large crater lakes at Waimangu has been monitored. Inferno Crater lake shows large water level variations (10 m) while the overflow of Frying Pan lake varies between 120 and 100 litres/sec.
The maximum depth of 589 m (1,932 ft) was established in 1959 by the USGS using sonar measurement. This depth is referenced at the surface elevation of 1,882 m (6,176 ft). But since its primary input source is dependent upon the climate, lake level is subject to abrupt changes. Crater Lake partially fills the collapsed caldera of the ancient Mount Mazama Volcano. The caldera is a bowl-shape depression of about 1,219 m (4,000 ft) deep.
