To update: MINV is available as a fractional share which can be used in place of MVOL. So as it stands the list of completely missing from the pies system ETFs is as follows:
JPGL (JPLG as an alternative)
IWQU (IS3Q or IWFQ as an alternative)
EMVL (5MVL as an alternative)
MVEU (EUN0, IMV or IMVU as an alternative)
WVAL (VALW as an alternative)
If these could be available as fractional shares I would be much obliged
