# Periodic Activity Tracker Periodic Activity Tracker is an indicator on [Vela](https://vela.luxalgo.com/chart), our next-generation charting platform, written in Pine Script®. Tracks cumulative buy and sell volume inside each hourly, daily, weekly, or monthly period, drawing gradient buy/sell lines, per-period volume bars, and the delta between the two sides. Delimiters and tags keep every period of the current cycle readable at a glance: the day's hours, the week's days, the month's weeks or the year's months. A participation gauge for traders who want to know which side is on the attack. - Indicator in the LuxAlgo Library, by LuxAlgo, published Mar 28, 2024. - Access: free. - Concepts: [Intraday Time-of-day Effects](https://www.luxalgo.com/library/concept/intraday-time-of-day-effects/) (primary), [Day-of-week Effects](https://www.luxalgo.com/library/concept/day-of-week-effects/), [Relative Volume](https://www.luxalgo.com/library/concept/relative-volume/) - Open on Vela: https://vela.luxalgo.com/chart?pineScriptCodeId=cmpwn4hm30069vhsgmlyhxbt9 - Page: https://www.luxalgo.com/library/indicator/periodic-activity-tracker/ **Periodic Activity Tracker** accumulates buy and sell volume separately inside each period you anchor it to (hourly, daily, weekly, or monthly) and draws the result as gradient-colored lines, per-period volume bars, and a running delta. Every period of the current cycle (the day's hours, the week's days, the month's weeks or the year's months) sits side by side with delimiters and tags, turning [intraday activity patterns](https://www.luxalgo.com/library/concept/intraday-time-of-day-effects/) and calendar rhythm into a direct read of which side is pressing. ## How to Trade the Periodic Activity Tracker? - **Green line climbing fastest**: aggressive buyers dominate the period's tape. - **Red line climbing fastest**: sellers are the ones attacking. - **Positive, expanding delta**: buyer strength with follow-through, the pattern that accompanies sustained pushes higher. - **Matched volumes, flat delta**: neither side in control, typical of ranging or contested periods. Reading periods in sequence shows the balance evolving: matched months followed by a surge in buy volume and a widening delta is the tracker's classic pressure-building sequence. Weekly and daily anchors likewise expose [day-of-week effects](https://www.luxalgo.com/library/concept/day-of-week-effects/) in participation. ## Periodic Activity Tracker Settings - **Anchor Period**: the aggregation window: Hourly, Daily, Weekly, or Monthly. - **Bar Width**: sizing of the per-period volume bars, with a warning at the maximum. - **Delta**: enables or disables the delta area. - Volume colors for each side are selectable. ## Frequently Asked Questions ### Which chart timeframe should I pair with each anchor? Keep the chart timeframe below the anchor period: five-minute or lower for Hourly, one-hour or lower for Daily, four-hour or lower for Weekly, and daily or lower for Monthly. The indicator raises a conflict warning when the combination doesn't work. ### How does it relate to Peak Trading Activity Graphs?
