Options Volume Tracker [S1S2]

Options Volume Tracker allows you to track the options volume for calls and puts expiring today (0DTE) or any other day available in the options chain.

Options Volume Tracker supports five instruments: /ES, /NQ, SPX, SPY, and QQQ.

The script highlights those strikes that have both calls and puts exceeding a volume threshold set for each instrument*. The script also marks the call and the put with the highest volume among the options visible in the table at any given time.

Options Volume Tracker is designed to track the volume filling activity according to the thresholds defined by BkBrown's PDVR theory.

Options Volume Tracker introduces a few new features compared to existing options volume trackers:

- If you want to track 0DTE volume only, there's no need to manually insert today's date
- If you want to track /ES or /NQ options volume, there's no need to manually define the prefix
- If you have a paid TradingView subscription, you can change the volume collection frequency from 1m to 1s or 1T
- Irrespective of your chart time frame, you can track the volume delta for an arbitrary period (default: 5min)
- You can highlight volume delta that crosses an arbitrary threshold (default: 1000)
- You can ask the script to automatically color the background of your chart when one or more strikes are "filled" (have both calls and puts exceeding the volume threshold set for each instrument*)
- The script tracks call/put ratio for each strike, and automatically highlights ratios with special significance (50/50, 17/83, 83/17).
- You can ask the script to automatically color the background of your chart with a special color when a strike reaches a significant call/put ratio.
- You can change the color of every component of the table, matching any chart style.

Thanks to these features, you can place multiple copies of Options Volume Tracker on the chart and track 0DTE, 1DTE, 2DTE side by side, or keep an eye on multiple instruments at the same time for confluence.

Limitations

Due to Pine's limitations, it's not possible to track calls/put volume for more than 19 strikes (a center strike + 9 strikes up and down).

The same limitation prevents the script from automatically identify the center strike and show 19 strikes at the same time. If you choose the automatic selection of the center strike, you'll only be able to see 3 strikes up and down the center strike, which is not very useful.

This means that you have to manually adjust the center strike as the market moves during the day.


*Call/put volume thresholds for each instruments are hardcoded.
