Currently the trading margin is between about 1:10 (on PNKS-CREP market) and 1:400 (on PNKS-XMR market). Margin is going to increase as the PNKS-PSTAR fork day is closing by (PSTAR will be launched on April 24th) and everyone is trying to hoard as many PNKS as possible due to PSTAR having low supply amount (120 million PSTAR). Trading volume is still too low for anyone to be able to sell enough PNKS to cover network fees for XMR withdrawal.
