It seems like there are many similar problems but I have not been able to find anything that addresses my issue exactly. I have a stock trading application, and I want to check if the price is out of a range (high,low) if the price goes below low, the problem is the rule keeps firing if the price keeps going lower, this creates too much noise and overhead. I thought maybe the no-loop and duration attributes would help but they didnt. I know I could check not(Fired()) and use insert fired but I believe that spans the entire session which I do not want either. Is there a way to say fire this rule if true once then wait a period of time before I check again. flexible enough. -- View this message in context: http://drools.46999.n3.nabble.com/fire-a-rule-only-once-for-the-time-bein...
