Is it possible to run out of buyers or sellers? Does this look different from a big buyer or seller at a particular area? For example, It would have been very convenient to have a double top at 91633 in AUD/USD but price stalled at 91631. It seems as if the buyers ran out of orders before they could polish off all the sells around 33 in order to hit the buys just behind it. Is it possible to be too short or too long in a currency?
