Hello Joel,<br><br>nothing on the LHS (between when and then) matters when a rule fires; so eval() and all other CEs are evaluated when facts are inserted.<br><br>So, trying to get rid of the eval's would be worthwhile.<br>
<br>The second thing (and I agree with Michael) is that you shoudl get rid of collect, which causes the delay during insertion. I'd also use a Collector fact with attributes for deal, a booking rule and a count.<br><br>
rule addCollector<br>when<br> $deal: <font size="2" color="black" face="Courier New"><span style="font-size: 10pt; font-family: "Courier New"; color: black;" lang="EN-GB">MarketDealModel()<br> not (Collector( deal == $deal )<br>
then<br> insert( new Collector( §deal ) );<br>end<br><br>When there is a matching Collector and a </span></font><font size="2" color="black" face="Courier New"><span style="font-size: 10pt; font-family: "Courier New"; color: black;" lang="EN-GB">BTExecutionBookingRuleModel matches </span></font>the deal:<br>
then<br> modify the collector by incrementing the count and storing the matched booking rule<br><br>At a lower salience, add 2 rules matching a collector with count == 1 and count != 1 with obvious consequences. (The second one could switch to the next level activation group.)<br>

use « exists » because I want one and only one booking rule of a specific
level (LEVEL_1, LEVEL_2, …) matching a deal, that’s why the bookingRuleModels
list collected should only contain 1 booking rule. This explain why in the RHS
I’m getting the first booking rule (bookingRuleModels.get(0)).</span></font></p>

<p><font size="2" color="blue" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: blue;">As an aside, you shouldn't need to use a
rule flow as the rules themselves determine which RHS is activated. Could you
consider using "exists" instead of the "ArrayList( size == 1)
from collect..." - it looks like you're not too bothered which Booking
Rule matches as (I believe) you have no way to determine which is at index(0).
Also, what do your "matchXXX" functions do? Could you investigate
removing the "evals"?</span></font></p>
