Candle extremes: finished and unfinished auctions

The highs and lows of a candle, or of a session, are not all alike. The footprint lets you tell apart an extreme where the auction ended naturally, for lack of participants, from an extreme where it was interrupted while buyers or sellers were still active. The latter have a statistical tendency to be revisited.

It is a fine reading, but a simple one to make: you only need to look at the very last cell at the top and at the bottom of the candle.
