Hmm... What range are you talking about? Is it a range of valid collateralization? I wonder if that could be it. The top short has a collateral ratio of 20,000 BTSX/BitBTC, but 1.5x13,518 is greater than 20,000. So that would mean that every short in the order book is currently invalid until the price of BTC falls a little more.
I think this 20,000 BTSX/BitBTC is just the collateral that person trying to open a short position provides (i.e. does not include the proceeds of the bitBTC sell), partly because the sell price is unknown...
Is there a lower bound on the allowable collateral? so if the price is 13,333, could you short at anything less than 20,000?
@ 13,333 the min will be 13333 BTSX
Ah, because the sale proceeds are 13,333 and those are also held as collateral, so you have 200% collateral after the sale. Thanks.
None of this explains why my bids weren't matching the short wall.
