yes Ref(Buy,-1) basicly shifts all elements of the array Buy 1 bar forward in time. The close price is used to trigger a signal. In reality it will be hard to develop a system that enters at the close except if you follow 1 stock or a few but if you track a few 1000 stocks then the earliest you can enter a position is at the open of the next bar.
