Easy Lang Help

["Tom" <profilic@xxxxxxxx>]

I am having a problem with the following:

I want to create a setup: SlowK crosses below 90 and then sell when a low
takes out the previous low.

"If L < L[1]" doesn't work because if the market first rallies, I want to
sell a low that takes out the previous low, even though it may be higher
than when the SlowK crossed below 10.

Any help would be appreciated.

Tom
