Oh my god my sanity is quickly slipping away. I cannot find in the manual any reference to the chart needing to have the same timeframe as the strategy. I can only find

"While Zorro is connected to MT4 in [Trade] mode, do not close the MT4 client window with the attached Zorro EA, and do not reset it to a different asset or time frame. Otherwise Zorro will become disconnected and display a red square next to the server window; it must then be stopped and restarted."

Did I just create this whole issue for myself?
