he's talking about something that being on the floor, having a squakbox or only modern math algo's are capable of detecting. it's a feel for excitement of market activity coupled with a good guess of directional mo. it's a feel you develop. mostly after you have lost your ass a few times being unaware of it. m
I think there is a formula for activity. Wyckoff draw some lines based on activity.maybe it’s relate to ATR or Volume.
From our trusty ChatGPT: Wyckoff's reference to "intensity of action (or activity)" refers to the energy or force behind market movements, which can be gauged through trading volume and how aggressively prices move during a given period. In his methodology, Wyckoff emphasized that price movements alone are not sufficient for accurate analysis; the strength of those movements, indicated by volume and the pace of transactions, offers deeper insight into market sentiment and trends. Here’s a breakdown of the concept: 1. **Volume**: The number of shares or contracts traded over a given period. A high volume indicates significant participation, which often reflects stronger conviction by market participants. Wyckoff encouraged correlating volume with price movements to understand whether trends were strong or weak. 2. **Intensity (Activity)**: This involves both the size of the price movement and how quickly it happens. A high-intensity move suggests strong buying or selling pressure, while a low-intensity move, even with a similar price change, indicates a weaker or more uncertain market. In essence, Wyckoff suggested that combining volume with price movement helps traders assess whether a trend has strong backing (e.g., large volume with a sharp rise or fall) or whether it’s weakening (e.g., smaller volume with sluggish movement). By focusing on this "intensity of action," traders could better time their entries and exits.
