Just curious here, why do you have this - signal : Signal( id == 1234 ) over window:length(1)?

Re: [rules-users] Help on writing a rule
Mauricio, In fact, I used to have this and the price change without window:length.. but when t : PriceChange() signal : Signal( id == 1234 ) not OrderCreated( id == 1234 ) over window:time (1m) But this will cause more and more duplicates orders (and it have sense!). I added the length window to 1, as I would only like to create an order if there is some signal in the window, it can place an order..

$city : City( name == paris )
not Person( age == 25, sex == female, city == $city )
For the other Qs look into collect and accumulate.
