It is easy to see that those short are not anxious to get shorter at this price so if you are not getting filled and want to be filled you might consider making a market order. I believe you wiill be filled regardless of size and since they would not want an abusive trade causing an investigation with the spotlight being shone on them likely at a fair price all things considered.

Short volume this week so far:
20191202|IPIX|237093|0|437585|O
20191203|IPIX|191686|0|219098|O
20191204|IPIX|429104|0|527900|O

So so far this week short volume of 857,883. out of total volume of 1,184,583
or 72% of this weeks volume has been recorded as being short sales. Those short have more than just a few problems. I hope by now most who read this board understand that the MM's utilize wash trades to simulate selling and walk down the price so it very well could be that were that not happening 100% of the volume would be shown as short.
The shorts are controlling the share price but are doing so at great risk because they have no control over the science and the science will prevail and that is exactly why longs continue not to sell but rather to accumulate much to the chagrin of the shorts.

Go IPIX!!!
