Bid Ask | Accumulates the volume of orders filled at the bid or less vs ask or more. Orders filled at the ask or more price are considered buying pressure. Orders filled at the bid or less price are considered selling pressure. If the current tick price is between ask and bid, the volume will be recorded to the same pressure as the previous tick. |
Up Down Tick | Accumulates the volume of up ticks vs down ticks. Up ticks are considered buying pressure. Down ticks are considered selling pressure. If the current tick price is the same as the previous tick price, the volume will be recorded to the same pressure as the previous tick. |
I wanted to clarify that in this context, "volume" is synonymous with "number" or "quantity" of up/down ticks. Put another way, is this value calculated by summing the number of up ticks vs the number of down ticks? As opposed to referring to a volume of orders filled.
Or, on the other hand, is it referring to volume as the quantity of contracts transacted at the moment of an up tick vs down tick.
Thanks!
