Western roll Osborn (1924), Walter Marty (1933), and Cornelius Johnson (1936). Johnson's record, (), was equaled on the same day by Dave Albritton, the first world record holder to use what we now call the straddle technique. At first, the straddle was viewed as just a variation of the Western roll, and indeed video of the 1936 Olympics shows Albritton using a conventional Western roll at lower heights. The straddle did not come to dominate the high jump until the mid-1950s, by which time it was recognized as a separate style. Walt Davis was the last Western roll jumper to hold the
Straddle year to expiry: After 50 days, the P/L graph of the straddle will look as follows (blue line): The P/L blue graph is "negative" at prices from approximately 84 to 107 dollars (these are the break-even points), which means that in order for the strategy to be profitable after 50 days, the stock price should be either higher than 107 dollars or lower than 84 dollars. As time goes by, due to time decay, the straddle P/L graph goes down (and becomes more and more unprofitable), until it reaches the orange line (which is the P/L of the straddle at
