AtlasFlow
Options premium traded per bar in its own pane, calls above zero and puts below, with filters for legs, sweeps, moneyness, side, DTE, premium and Flow Score.
Flow puts the options premium that traded in each bar in a pane under the chart. Call premium draws above zero, put premium below, in your candle colours. It's the quickest way to see whether a push in SPY came with real options money behind it, and which side that money was on.
Every pane has its own filters. Add one Flow pane for everything, and a second filtered to ask-side sweeps over $250K, and you can watch the whole tape and the aggressive size side by side.
Adding the indicator
Open the chart settings panel and use the Add button in the Indicators section. Flow sits in the Subpane group. You can add up to four, each in its own pane with its own filters, and each always follows the chart's symbol.
Settings
Every filter starts wide open. A pill group always keeps at least one option on.
| Setting | Options | What it controls |
|---|---|---|
| Leg Count | Single, Multi (both on) | Single-leg trades, multi-leg spreads, or both. |
| Trade Type | Sweep, Non-Sweep (both on) | Sweeps only, everything else only, or both. |
| Moneyness | ITM, ATM, OTM (all on) | Which strikes relative to the stock price count. |
| Trade Side | Bid, Mid, Ask (all on) | Where the trade printed against the quote. |
| DTE | Min and max days to expiration (blank) | Limits the expirations that count. |
| Premium | Min and max premium (blank) | Only trades in this premium range. Accepts shorthand like 250k or 1.5m. |
| Flow Score % | Minimum score, 0 to 100 (blank) | Only trades scoring at least this high. |
| Sweep C/P Ratio | Off (default), On | Overlays a line of sweep call premium divided by sweep put premium, with a 1.0 baseline. Above 1.0, more sweep money went to calls. |
Reading notes
- The row label tells you the filter. An unfiltered pane reads "Flow". A filtered one spells it out, like "Flow · Single · OTM · Ask", so two panes are easy to tell apart.
- Each bar sums the premium that matched your filters in that bar's time window, so a filtered pane will always look smaller than the unfiltered one. Compare shapes, not just heights.
- Premium isn't direction on its own. Ask-side call premium leans bullish, but a big bid-side print could be someone selling. Use the Trade Side filter when the side matters.
- Want a running total instead? Net Premium adds bought minus sold premium up through the session.
