Hi
I'm trying to understand what is wrong with this rule. It validates in
guvnor, but when running it throws an error.
I am trying to write a rule that will fire if there have been less than ten
trades in ten minutes.
This is the rule:
1. | rule "Trade Count"
2. | dialect "mvel"
3. | when
4. | Number( trades : intValue < 10 )
5. | from accumulate(
6. | e: TradeOrder( )
7. | over window:size(10m),
8. | count(e) )
9. | then
10. | TradeOrder silverTrade = new TradeOrder();
11. | silverTrade.setMt4username( "4002642" );
12. | silverTrade.setOperation( "OP_BUY" );
13. | silverTrade.setStatus( OrderStatus.OPENING );
14. | silverTrade.setSymbol( "SILVER" );
15. | silverTrade.setVolume( 1 );
16. | silverTrade.setOrderLots( 2 );
17. | insert( silverTrade );
18. |
19. |
20. | modifiedOrderList.add(silverTrade);
21. | end
What I assume to be the relevant portion of the stack trace is here:
