Hi Smallz, Hi Zorro team,

the Zorro documentation is now excellent with respect to updating the system, while running a strategy (own or Z). This is the link:

However, there is one mystery, when updating a system while running the Z12 strategy. When i move the capital slider on the old version to 0, indeed no new positions open, and most of the existing positions close. All but two short FX positions one CX and one from CY algorithm.

Is there any time threshold how long the old instance should run in parallel with the new update ? I suspect, 2 months is too much for any of the Z12 algorithms? Thank you for any hint ...
