I believe tick() works for both Zorro and Zorro S. But you can only use BarPeriod 1 or greater in free Zorro. So if you're only using run() and BarPeriod is 1, then you only get price updates once per run(), which is once per minute.
I didn't know about tick(). It does seem to be working with free Zorro.
My understanding of the manual is that in tick(), priceClose() gives the ask quote. So how does one get the trade price when a trade occurs?
