[rules-users] Help on writing a rule
Hi Guys. I have one quesiton on how could I implement my rule.
I have this rule:
when
t : PriceChange() over window:length(1)
signal : Signal( id == "1234" ) over window:length(1)
not OrderCreated( id == "1234" ) over window:time (1m)
then
insert(new OrderCreated("1234));
Basically, when there is some signal and some price change, create a new
order if there has no been any other order in the last minute.
But this sometimes is being fired twice:
12:31:01,121 INFO [org.drools.audit.WorkingMemoryConsoleLogger] (Camel
(camel-1) thread #4 - JmsConsumer[marketDataTopic]) ACTIVATION CREATED
rule:ertetr activationId:ertetr [393, 392, 0] declarations: t=PriceChange
[](392); signal=Signal@1413ddef(393)
12:31:01,160 INFO [org.drools.audit.WorkingMemoryConsoleLogger] (Camel
(camel-1) thread #4 - JmsConsumer[marketDataTopic]) ACTIVATION CREATED
rule:ertetr activationId:ertetr [393, 394, 0] declarations: t=PriceChange
[](394); signal=Signal@1413ddef(393)
I think that, when the 1m window have passed, it creates twice the
activations, as I have not called fire all rules yet. Does is make sense? Do
you have some idea on how could I implement this rule? "when there has been
some price change and some signal, and I did not create a new order in the
last minute, just create a new order".
Thanks in advance!
Demian
