I absolutely understand this, and I know that there are no prices and trading on the weekends. I am trying to understand how Zorro is supposed to function with interruptions in service

As in on Sunday afternoon, will it start trading with a continuation of friday's prices or will it start a brand new look back period? You see if you are trading 4 hr bars and your waiting for a lookback every sunday you effectively waste a large fraction of the week waiting for your lookback period to complete. If you were unlucky to have been disconnected then the lookback starts over. I wanted to know if there was a way I can use the historical close prices of the last 40 bars so that it can resume trading instantaneously upon turning it on.

If Zorro needs to be on continuously to function then I will have to run it of virtual private server, otherwise I will spend most of my trading waiting for lookback periods to finish. That is why i was asking the question so I can decide on how to best proceed. Again, many thanks jcl, I appreciate your input, I am merely trying to understand how Zorro is supposed to function through breaks in service.
