The test is whether the S&P made a new 99 day high in the last 99 days.

The GTR1 version of DBE checks for 99-day high over the past 99 days.

Create [DBE]: [Maximum of [[[Closing g-price]/[Highest closing g-price over 98 days]] > 1 ? 1 : 0] over 99 days]
step0: [DBE] == 1; Cash When None
Holding period = 1 mkt days
