Only what matters, by default
Candles, volume, VWAP and the levels traders actually trade around. Nothing else is on the screen until you ask for it.
Desktop charting for SPX and ES traders
Zyrova Chart:SPX and ES Trading Charts with Automatic Market Levels
Built for Interactive Brokers (IBKR) account holders
A clean chart with the levels that matter, already drawn.
Zyrova Chart is a Windows desktop charting app for SPX and ES futures traders who use Interactive Brokers. Most charts bury price under dozens of lines, panels and pop-ups. Zyrova Chart starts from the opposite side: candles, volume, VWAP and the levels SPX and ES traders watch every day, drawn for you before the open. Prior day, overnight, opening range and the expected move, with a clear mark when price grabs, sweeps or retests one of them. Everything else is one switch away, and off until you want it.
Needs an Interactive Brokers account with market data, TWS (Trader Workstation), and a Windows 10 or 11 PC. How it works
Zyrova Chart is an analytical tool. Its levels and readings describe the market. They are not trading signals or advice and do not guarantee results. Trading involves substantial risk of loss.
How it works
Your IBKR account, your PC, your charts.
Zyrova Chart doesn't sell or send market data. It reads the prices your own Interactive Brokers account already gets, through TWS running on your computer, and draws them as clean charts with the key levels on.
Broker
Interactive Brokers
Your account and its market data subscriptions
On your PC
TWS
IBKR's free trading platform. You sign in and trade here, not in Zyrova.
On your PC
Zyrova Chart
Charts, key levels, alerts. No orders.
Zyrova never sees your IBKR login, account, positions or trades. The only thing the app sends to Zyrova is a license key check.
Step 1
Have an IBKR account
With market data: Cboe index data for SPX, CME for ES, OPRA for the expected move.
Step 2
Install on Windows
Install TWS (free from Interactive Brokers) if you don't have it yet, and Zyrova Chart, a 5.5 MB installer.
Step 3
Log in to TWS
Turn on its API once in Global Configuration. Zyrova Chart finds TWS on your PC and offers to open it if it isn't running.
Step 4
Charts load with levels on
Prior day, overnight, opening range and the expected move are drawn for you.
Not with IBKR? Zyrova Chart works only with Interactive Brokers for now. Try it free for 7 days before you buy to make sure your account and data work.
Step-by-step setup guideSimplicity first
Less on the screen. More time reading price.
When a trade is moving, you don't have time to look for the one line that matters among twenty. Zyrova Chart is built around a simple rule: if a trader doesn't look at it every day, it isn't on the chart by default.
Every extra is one switch
Supply and demand, fair value gaps, big trades, delta, sweeps and marks each sit on their own switch in one panel. Turn on what you use and forget the rest.
Labels stay out of the way
Levels are short codes like PDH, ONL and ORH beside the price axis, in the gap right of the last candle. They never sit on top of price.
One click to a bare chart
The eye button on each chart hides every level and indicator and leaves just the candles, for when you want to read price alone.
What we left out on purpose
- No ads, no pop-ups and no social feed
- No library of hundreds of indicators to scroll through
- No news ticker or chat panel competing for your eyes
- No cloud: your charts, drawings and price history stay on your PC
Key levels
The levels are drawn before you look.
You shouldn't have to redraw yesterday's high every morning. Zyrova Chart works out the levels from the candles and draws them as soon as the chart opens, refreshing every minute. The levels are on the chart before the session gets busy, so your plan is written down before the move, not after.
Prior day high, low and close
Where yesterday's buyers and sellers stopped. The first places price is likely to react.
Overnight high and low
Taken from ES and shifted onto SPX, so an SPX chart shows where the futures traded while the index was closed.
Opening range
The high and low of the first 15 minutes after 9:30, the range many traders use to judge whether the day is going to trend.
Expected move
The options market's expected range for today, from the 9:30 at-the-money straddle, drawn above and below the open.
EM used
Next to the price: how much of today's expected move price has already travelled, so you know when the usual day's range is spent.
Today open, day high and low, prior week, round numbers
Ready in the same panel, off by default, one switch each.
Bells on levels
Tap the bell next to a level and the app plays one sound, with a short note, when price comes within the distance you set. No need to stare at the chart while you wait for price to get there.
Tests at your levels
See what price did when it got there.
A level is only useful if you can see how price treats it. Zyrova Chart marks the moments that matter at the prior day, overnight and opening range levels, with small, quiet symbols instead of arrows all over the chart. Both sets of marks are two small buttons on the panel, off until you turn them on.
Grab
A wick pokes through a key level and the same candle closes back inside. A solid triangle marks it.
Sweep
Price closes beyond a key level, then comes back inside within 3 candles. A hollow triangle marks it.
Retest
Price breaks a level, holds beyond it, then comes back to it from the new side and holds. A small diamond marks it.
VWAP reclaim and lost
A small mark when price closes back above VWAP after a run below it, or below after a run above. At most one every 30 minutes, so it never crowds the chart.
Marks describe what already happened on a closed candle. They are not signals and do not say what price will do next.
Market reading
Read the whole market in one line.
SPX doesn't move alone. A strip under the charts reads NYSE TICK, ADD and VOLD for you and says in one sentence whether buyers, sellers or neither are in control, so you can see the wider market behind a move at a glance.
One label, one sentence
TICK, ADD and VOLD turned into plain English: Buyers in control, Sellers in control or Mixed market, and one line on what that usually means for the day.
Today's TICK
Every NYSE TICK reading of the session as green and red bars under the charts, so you see when buying or selling waves hit.
Trend row
Up, down or mixed on the 1, 5, 15 and 60-minute candles for each chart's symbol, in the chart's header. When all four agree, the trend is clear.
The reading describes the market right now. It is not a signal and does not say what price will do next.
Steady data
Stays connected, so you don't have to watch it.
A chart that quietly freezes is worse than no chart. Zyrova Chart watches its own connection to TWS and every price feed, fixes what it can by itself, and shows you plainly when something is off.
Opens TWS for you
If TWS isn't running, the app offers to open it. After you log in, the charts load by themselves. If TWS's API is off, it tells you which setting to change.
Reconnects on its own
When the connection drops, after TWS's nightly restart or a Wi-Fi blip, Zyrova Chart reconnects and picks every chart back up.
Fills the gaps
After any drop it reloads the candles it missed, and every 2 minutes it checks the newest candles against Interactive Brokers' own.
A dot that tells you
A small dot by each symbol: green when prices are live, amber when none came for a while with the market open, red while it reconnects.
A day with Zyrova Chart
From the morning plan to the evening review.
Before the open
Open the app and the prior day, prior close and overnight levels are already drawn. Set a price alert on the level you care about and leave it.
At 9:30
A thin line marks the open. After 15 minutes the opening range is drawn, and the expected move appears from the open.
During the day
Watch how price behaves at each level: a grab, a sweep, a break and retest, VWAP reclaimed or lost. EM used tells you how much room the day usually has left.
After the close
Replay the day candle by candle with the levels as they stood, and practise your entries before tomorrow.
Order flow on the chart
Big trades and delta, without a second app.
Turn on Big trades and every large trade shows as a bubble at its price: green when a buyer lifted the offer, red when a seller hit the bid, bigger for more size. You set the minimum size per symbol, 50 ES contracts to start.
Turn on Delta and a thin pane under the volume shows buying minus selling in each candle, with the cumulative delta line restarting at 9:30. When price makes a new high and delta doesn't, you see it.
On an SPX chart both come from ES trades, because the index itself has no trades to read.
Bar replay
Practise yesterday before you trade today.
Pick a day and the chart goes back to that morning. Play it at 1 to 10 candles a second, pause with Space, or step one candle at a time with the arrow key. The key levels are worked out as they stood that day, so you see exactly what you would have seen live.
Press Buy, Sell or Flat to take practice trades at the candle close and see the result in points. Nothing is sent to your broker, and nothing from replay is saved.
Compare
See who is leading, on one chart.
Press Compare and add up to two more symbols. Each one becomes a line showing its percent change from the same starting point, so SPX, SPY and the Dow sit on one scale and you can see at a glance which is stronger and which is lagging.
When SPX holds up while the Dow slips, or SPY breaks away from SPX, it shows right away. Each line keeps its own colour and its change sits at the price axis. It works on every timeframe down to 1-second candles. The red × next to a symbol removes it, and removing the last one puts the candles back.
Everything you need, nothing in the way
A full charting app when you want one.
Simple doesn't mean limited. The tools are there, they just wait in the side rail and the panel until you reach for them.
Layouts
One, two side by side, two stacked, or four charts, each with its own symbol and timeframe. It opens with SPX 5-minute over ES 1-minute. Save layouts and switch in one click.
Detachable windows
Pop any chart into its own window for a second monitor. Keep it independent or link it to follow the main window's symbol.
Timeframes
1 second to weekly. Up to three years of daily candles, and the history you load is kept on your PC so it opens instantly next time.
Drawing tools
Trend line, ray, horizontal line, rectangle, Fibonacci, long and short position box, parallel channel, fixed range volume profile, text notes, with a magnet to snap to candles.
Alerts
Right-click a key level, a price line or a trend line to be alerted when price crosses it.
Session volume profile
Where volume traded today, beside the price axis, with buying and selling in two colours. The busiest price shows its buyer and seller split, and any bar shows its own on hover.
Snapshots
The camera button copies a picture of one chart, all charts or an area you drag, ready to paste into a chat or journal, and saves it as a file too.
Watchlist
Your symbols with live prices and change on the day. Drag to reorder, click to load.
Light and private
Fast to start, light to run, yours to keep.

It starts in a moment, redraws only when a new price arrives, and keeps everything on your own computer. It talks to your broker's TWS on your PC and nothing else.

Questions
Frequently asked.
Does Zyrova Chart tell me when to buy or sell?
No. It draws levels and marks what price did at them. It never recommends buying, selling or holding anything, and any level or mark can fail. You make every decision.
Does Zyrova Chart place trades?
No. It has no order entry and never sends orders. Buy, Sell and Flat in bar replay are practice entries on past candles and stay inside the replay.
Do I need an Interactive Brokers account?
Yes. Zyrova Chart is built for IBKR account holders and has no data feed of its own. You need an IBKR account with the market data subscriptions for what you chart, and TWS installed and logged in on the same PC. The setup guide at zyrova.com/zyrova-chart/setup walks you through it.
Why is it so simple?
Because most of the screen in other charting tools is something you don't use. Zyrova Chart starts with the few things SPX and ES traders look at every day and puts everything else on a switch, so you decide what is on your chart.
Where does the data come from?
From your own Interactive Brokers account through TWS (Trader Workstation) on your computer, with the market data subscriptions on that account. Zyrova Chart has no data feed of its own.
Where is my data kept?
On your PC. Candle history, drawings, alerts, layouts and settings are saved locally and never sent to Zyrova.
Where do the overnight levels on SPX come from?
SPX doesn't trade overnight, so the overnight high and low come from ES and are shifted onto SPX by the ES to SPX difference.
How is the expected move worked out?
From the at-the-money SPX straddle at the 9:30 open, drawn above and below the open. It needs OPRA options data on your account, and it is the market's priced range, not a forecast.
Is the market reading a signal?
No. It describes what NYSE TICK, ADD and VOLD are doing right now in plain words. It doesn't predict where price goes next, and markets often do the opposite of what the breadth suggests.
What happens if TWS disconnects?
The dot by each symbol turns red, the app reconnects by itself and reloads the candles it missed. If TWS isn't running at all, the app offers to open it for you.
Can I use IB Gateway instead of TWS?
Zyrova Chart connects through TWS. IBKR lets one username be logged in at one place at a time, so with IB Gateway you couldn't trade in TWS while charting; logging in to TWS would knock Gateway, and your charts, off. With TWS you chart and trade from the same login.
Do I need to keep it open for big trades and delta?
Yes. They are built from the every-trade feed while the app runs, so start it before 9:30. Today's are kept if you restart.
Will it slow my computer down?
It is a native app that takes 16.9 MB on your PC, and charts only redraw when a new price arrives, so it stays light even with four charts streaming.
Does it work on Mac?
Zyrova Chart is built for Windows 10 and 11.
What does it cost?
$19.99 a month or $199 a year, with everything included and a 7-day free trial. The first 100 customers on the yearly plan pay $99.50 for their first year (50% off). The monthly plan is always $19.99.
Is there a free trial?
Yes, 7 days for everyone. Enter your email in the app and the trial key arrives by email. No card is needed to start.
How many computers can I use it on?
One subscription works on 1 Windows PC at a time. You can move it to a new PC from inside the app.
Zyrova Chart is charting software only, not trading advice. You make every trading decision and trade at your own risk.
Important Zyrova Chart disclosure
Disclosure version: ZYROVA-CHART-RISK-2026-11-01-v3
This product-specific disclosure supplements the company-wide Zyrova Technologies Terms of Service. Zyrova Chart is desktop charting software. It displays prices, candles, volume, key levels, expected moves, indicators, marks, alerts and replays for informational and educational purposes only. Website screenshots use sample prices from the app's built-in simulator and are not trading results.
Zyrova Technologies LLC is not a broker-dealer, investment adviser, commodity trading adviser, fiduciary, exchange, tax adviser, legal adviser, or trade-execution service. Nothing shown by Zyrova Chart is individualized investment advice, a suitability determination, an offer or solicitation, or a recommendation or instruction to buy, sell, hold, or trade any security, option, futures contract, derivative, or other financial instrument. Zyrova Chart does not place or execute trades. Buy, Sell and Flat in bar replay are practice entries on past candles only and never send orders.
Labels such as key level, expected move, EM used, grab, sweep, retest, VWAP reclaim or lost, supply, demand, fair value gap, big trade, delta, trend, buyers in control, sellers in control, mixed market, TICK, ADD, VOLD or similar describe software-generated market context only. They are not predictions, guarantees, signals or instructions to trade, and the same rules applied to past data do not mean the same outcome in the future. Features, calculations, thresholds, terminology, pricing and packaging may change, be corrected, or be discontinued as the product evolves, subject to applicable law and binding written commitments.
Zyrova Chart shows the market data that your own Interactive Brokers account and subscriptions provide through TWS (Trader Workstation). Prices, history, levels, trade classifications, alerts and other displays may be delayed, incomplete, inaccurate, or unavailable. Zyrova Chart depends on third-party services and infrastructure, including Interactive Brokers, TWS, market data providers, payment processors, hosting providers, internet connectivity, computer hardware, and other external services. These services may change over time. Zyrova is responsible for the development and operation of its own software, but does not control independent broker, market data, operating system, network, or other third-party services on which the Software may depend. Interruptions, delays, errors, or changes in those services may affect Zyrova Chart. Zyrova remains responsible for its own software and obligations under applicable law. Alerts and level sounds may not fire or may fire late, and the live feed indicator, automatic reconnection and candle corrections cannot guarantee that every price is received or shown on time. Interactive Brokers is a trademark of its owner; Zyrova Chart is not affiliated with, endorsed by, or sponsored by Interactive Brokers.
Trading and investing involve substantial risk. Options (including same-day-expiration options), futures, other leveraged instruments, and short-dated strategies can lose value rapidly, including the possible loss of the entire amount committed, and some strategies may expose you to losses greater than the initial amount committed. Replay results, practice P&L, examples, historical levels and statistics are not guarantees or indicators of future results.
You are solely responsible for verifying what you see, evaluating suitability, choosing position size, configuring your broker, deciding whether to trade, and making your own financial, tax, and legal decisions. You manage your own trading risk and use Zyrova Chart at your own risk. Use of Zyrova Chart is subject to the Terms of Service, including the warranty disclaimers and limitation-of-liability provisions stated there. No marketing statement, example, or informal communication overrides those Terms unless Zyrova expressly agrees otherwise in a signed writing. Nothing in this disclosure excludes or limits any responsibility that cannot legally be excluded or limited.
