Credit goes to Shizaru for the original calculation. I made just a few fixes, so that the calculation is really that of Ehlers.
Fixed H2 and L2 period, fixed w natural logarithm

Release Notes:

@version=2 to @version=4

Release Notes:

fixed input(close) that was ignored in the last version

Release Notes:

Converted to v5.
Replaced the awkward log w by -4.6, as in the original white paper.
Replaced the dimen by variable assignment, to make the calculation a bit more clear.
