If I were buying NNVC on margin would I be stupid enough to do that with a broker who is going to increase the margin requirement to 100% as soon as the price gets at or below $5 -- a price level that NNVC has been at very frequently over the past 5 months? Would anyone else be that stupid?
I think you protest the Evil IB Margin Requirement overmuch. I suspect it actually has a negligible effect on NNVC's stock price.
