Yes! I receive many price change events.. but, as I am using window length = 1, I would expect to have the activation cancelled for the previous one?

I am not sure how to express this:
"when there is some price change, and some signal, and there has not been any order over the last minute, then place an order"

The price change and signal are like "existence" facts.. "If there is some price change change.." "if there is some signal ..."

Would this be another way to achieve what I am trying to do?

Thanks,

Demian

PS: This is a simple rule, but then, the idea is to have more complex rules.. like, if there has been 10 signals in the last time, place an order, etc.

Am I wrong or do you have two PriceChange events - 392 and 394 ?
If so, you can expect two activations.. when you fire al rules, one of
the two
will insert the OrderCreated, which in turn will cancel the other
