b2 - rembrandt eto's or warrants

Hi Rembrandt. Thank you for your comments .
I noticed NCP before the market opened yesterday and also noticed the NCPWMF were $0.16 at the open .
Is it possible to buy warrants and or ETO's in volume say $10,000 worth a lick and be able to find a buyer when one sells out please?
I thought with ETO's one could want to sell and there may not be a buyer in sight ? On warrants I thought they were different if there was a Jobber like Macquarries , or would they not take volume back or screww one down on price.
Any further advice you could let me have will be appreciated.
Thank you
best wishes
