ZenAlgo - Control
Control places important volume-profile levels from several calendar periods directly on the price chart. It helps answer a practical question: where did the market previously accept value, and where is value developing now?
How to read it
For every enabled period, begin with the developing POC. It moves as the current period accumulates volume and shows where activity is concentrating now. Previous-period POC, VAH, and VAL are fixed references from a completed profile.
Price returning to one of these levels may pause, reject, or accept through it. A hit is therefore a prompt to inspect price behavior, not a prediction of the response.
Lines and values
| Label | Meaning |
|---|---|
| dPOC | Developing point of control for the current period |
| POC | Point of control from the previous completed period |
| VAH | Previous value-area high |
| VAL | Previous value-area low |
| W / M / Q / S / Y | Weekly, monthly, quarterly, semiannual, and yearly profile |
The available periods depend on chart timeframe so that the profile receives useful lower-timeframe data. Weekly levels are intended for intraday charts; longer periods become available on progressively higher intraday timeframes.
Alerts
Control provides the same four alerts for each of W, M, Q, S, and Y, for a total of 20 alert conditions:
| Alert family | Meaning |
|---|---|
| dPOC HIT | Price reaches the current period's developing POC |
| POC HIT | Price reaches the previous period's POC |
| VAH HIT | Price reaches the previous value-area high |
| VAL HIT | Price reaches the previous value-area low |
Use dPOC alerts to follow changing current value. POC/VAH/VAL alerts are better for preparing around fixed historical levels. Alert behavior can be configured around touches, crosses, and current or previous levels.
