Re: [rules-users] Writing a pattern in which each event constraint depends on the previous event

how about numbering your ticks ? as a rough outline, this might look something like: 1st : Tick ($number : num) 2nd : Tick (num == $number+1, {this.value below 1st.value}) 3rd : Tick (num == $number+2, {this.value above 2nd.value}) this should find all "bottoms" -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Writing-a-pattern-in-...
