Re: [rules-users] error when referening LHS->exists block var in RHS

As long as you can say "how close" you want using an absolute number, it is possible: let's say you want all tickers that happened up to 10 minutes before a given timestamp: rule "Pseudo rule" when ArrayList() from collect( Ticker( price == 20.00, timeInMillsec before[1ms,10m] 1000000 )) then //do conseq end You can replace your timestamp (1000000) above with a Date variable or something like it.
