A volume profile for every group of candles — buying and selling at each price, with the totals underneath.
Chart pictures are illustrations of the software, not a performance record. Futures trading carries substantial risk of loss and is not suitable for every investor, and hypothetical or simulated results have inherent limitations that may differ materially from live trading. Risk disclosures.
Why you need it
A candle tells you where the market went. It doesn't tell you where inside that range the volume traded, or whether buyers or sellers were doing the pressing. DS Flow x-rays groups of candles into a volume-by-price profile — a horizontal bar at every price level, split into buying and selling, with the heavy, statistically significant levels marked — so you get hidden support and resistance, absorption and exhaustion, and value migration across groups, not just a shape.
What the rows tell you
Each group of candles is x-rayed into a volume-by-price profile: one row per price, split into buy and sell, the longest row the fairest price.
Before you buy
Where it runs
Futures and stocks
It profiles traded volume, split into buying and selling. Forex and CFDs have no trade tape in NinjaTrader.
What it reads
Traded volume at each price; the bid/ask of each live trade. Loaded history is estimated from one lower-timeframe series (1 minute by default), no tick download.
NinjaTrader 8 · 8.1.8.1 or newer. Everything runs on your machine, on your own data feed.
Good to know
Detail scales cleanly with zoom, and DS Toolkit can show or hide the whole overlay from the toolbar.
DS Universe tools are charting and research software for educational and informational purposes. They are not investment advice and no output is a forecast or a guarantee of any result. Trading futures and other leveraged instruments carries substantial risk of loss and is not suitable for every investor.

Four screenshots and a paragraph are not enough to judge an indicator on. Watch it work in your own instrument, on your own timeframe, before it goes anywhere near a live account. Both ways of doing that are free.
DS Flow itself is free for three days — time to replay sessions you remember and trade it forward on the simulator before you pay anything. Replay runs a past session at any speed, so the three days hold far more than three sessions.
Start free trialMarket Replay runs a past session back tick by tick, at whatever speed you like. You get to watch DS Flow print in conditions you remember, and pause on the bars where it mattered.
Replay shows you the past with the ending already known. The simulator does not — it runs live, in real time, on real prices, with nothing at stake. That is where you find out whether you can actually act on what you are seeing.
A simulated fill is not a live fill. Replay and the simulator cannot reproduce real queue position, slippage, or what it feels like to hold a position with money on it, and results from either may differ materially from live trading. Test to learn how a tool behaves — not to estimate what it might return.
See it work
The conditions DS Flow is built for, drawn by its shipped rules. Scroll and scale it like a chart, replay it bar by bar, jump between its moments, or switch the chart to light.
DS Replay examples are illustrative: each scenario is composed for the example from recorded one-minute futures candles, to show the conditions a tool is built for, and is not a recording of a trading session. The tool drawing on it runs its shipped rules unchanged. They show how the software reads price; they are not a performance record, no trade is taken or shown, and live markets often behave differently. Futures trading carries substantial risk of loss and is not suitable for every investor, and hypothetical or simulated results have inherent limitations that may differ materially from live trading.
