1. (a) From the picture of the generator, we compute |
![]() |
dY1 = 0.5, dY2 = -0.25, dY3 = 0.25, dY4 = 0.5 |
dt1 = dt2 = dt3 = dt4 = 0.25 |
(b) All the dti are equal, not all the dYi are equal, so
not all the Hi = |
(c) To find the Trading time generators, first solve the equation |
|dY1|D + |dY2|D + |dY3|D + |dY4|D = 1 |
Here this becomes |
.5D + .25D + .25D + .5D = 1 |
The solution is D = 1.45 |
Then the Trading time generators are dTi = |dYi|D. That is, |
dT1 = dT4 = .51.45 = 0.366   and   dT2 = dT3 = .251.45 = 0.134 |
