why is MegaVault making a loss of $56,377 on a token with zero volume, zero trades and zero open interest
The screenshots you cited are comparing 30d p&l against 24h volume/trades/open interest. The MegaVault operator has mandates to provide liquidity to tail markets which tend to experience spikey one-sided flow i.e. sometimes there will be a lot of volume and trading, and sometimes there is none.
