that 3 times today I tried a little experiment picking up enough shares to clear the ask up to the next penny. All three occasions were met with immediate replenishing of a few shares at the same sp I purchased at. It's been slow and there were long periods without activity when I did this. I say again the replenishing was immediate... as though it were a program that could respond without delay. I wonder, how is that done. I know that there are financial institutions with faster connections than we retailers. It strikes me that their computer gets a look at what I'm doing simultaneously with my transaction. Once or twice maybe co-incidence but three times?
