Mauricio, In fact, I used to have this and the price change without window:length.. but when t : PriceChange() signal : Signal( id == "1234" ) not OrderCreated( id == "1234" ) over window:time (1m)
But this will cause more and more duplicates orders (and it have sense!). I added the length window to 1, as I would only like to create an order if there is some signal in the window, it can place an order..
