Is there a way to count the number of times a certain event has occured since the last time a different event occured?

Silly example - count the number of times a 52-week high has been set since the last time a 52-week low was set.

I thought that something like the following would work:

set{DAYS_SINCE_LOW,days(low reached new 52 week low,100)}
set{NUM_HIGHS,count(high reached new 52 week high,DAYS_SINCE_LOW)}

But debug says, "Warning: no period specified for count." Note that this is not the same error generated by a period of 0.

Any other ways?

Thanks!

maybe...

Fetcher[

set{DAYS_SINCE_LOW,days(low reached new 52 week low,100)}
set{NUM_HIGHS,count(DAYS_SINCE_LOW below .5,100)}

add column DAYS_SINCE_LOW
add column NUM_HIGHS

draw NUM_HIGHS
draw DAYS_SINCE_LOW
]
