Did Zeev use Fifo or Lifo? The way I remember it, he would buy a "first serving", and then a second, third - sometimes up to five servings - as the price continued down.
Then he would sell them in reverse order as the price rose. He would often enter and exit a fourth or third serving several times before the price rose enough for him to focus on his second and then first servings.
So his "last in" buy was his "first out" sell. That's Lifo.
