What pros actually use
Every edge a serious trader pays for — on desktop, in the browser, free.
Order flow, liquidity, profile, alerts, automation, and a dashboard that brings every saved workspace one click away. Desktop on Mac, Windows, Linux. Browser on anything else. Same app, same speed, same price — zero.
See who's buying — every single candle
Footprint reveals real bid vs ask volume inside every bar. Spot exhaustion, absorption, and the move before it shows up on price.
See how it works
The big orders, before they fire
Watch large players stack liquidity on the heatmap. When the wall moves, you see it first — not after the fill.

Where the market actually trades
Volume profile and value area show where price is fair. Reversion or breakout — let the levels make the call for you.
See how it worksOne click to fire. One click to cancel.
The full order book on a ladder. Click bids to go long, asks to go short, drag-to-modify right on the chart.
See how it worksEleven alert kinds. One unified builder.
Price, indicator, drawing, composite, orderflow, cross-feed, position, market state, time, pattern, and custom DSL. Fires 24/7 from our cloud — pushes to Discord, Telegram, generic webhooks, email, OS notification, and in-app toast. Snooze 10 min from any toast; the worker honours it server-side.

Live headlines from Wall Street, Reuters, Yahoo and others — filtered to whatever symbol you're on. No tab-switching, no missed catalysts.

BeforeAfter
Layout · workspace transformation
From single chart to mission control.
Start with one chart. Dock the DOM ladder, footprint, order-book heatmap, and positions panel. Save the layout. Spectra remembers it across every device you sign in on.
BeforeAfter
Chart layers · price to proof
Bare candles vs. the full order-flow picture.
Footprint cells, VWAP, anchored volume profile, value-area shading. Same instrument, same bars — the right side reveals what the tape is actually doing under each candle.
Drawings · live demo
Trendlines that tag the chart in real time.
Drop a trendline, attach a horizontal level, watch the renderer hold 144 fps as price walks straight into your zone. No lag, no janky redraw.
Paper trading · real matching engine
A paper book that fills like the real market.
Most paper trading is a screenshot — type a price, get a fill, done. Spectra simulates the real exchange: orders match against live bid/ask, slippage scales with size, partial fills happen, time-in-force is respected. The mistakes you make on paper are the same mistakes you'd make with money.
A real matching engine
Limit, market, stop, stop-limit, OCO, bracket — every order type routes through the same engine that powers live trading, against the live order book.
Realistic fills + slippage
Orders fight for the inside quote. Size moves price. Partial fills land in pieces. Backtest equity finally matches what live execution would have delivered.
TP / SL that fires while you sleep
The same cloud worker that watches alerts watches your paper positions. Take-profit and stop-loss auto-close 24/7 — your laptop being shut doesn't unmount the trade.
Every position, every device
Paper book lives in Supabase, syncs across native + web in real time. Open a position on the desktop, close it from the phone on the train home.
Alerts · 11 categories · all outbound channels
An alert engine that fires while your laptop is closed.
Spectra's alerts run on a dedicated cloud worker, not on your machine. Close the lid, the worker keeps watching. Eleven alert categories — from a simple price cross to a custom boolean expression in our scripting DSL — fan out to in-app, email, Discord, Telegram, Slack, custom webhooks, OS push, and sound. Every alert is independent, every channel is per-alert.
11 alert categories
Price cross
Above, below, or either-direction at a fixed price.
Drawing touch
Fires when price touches a line, channel, fib, or rectangle on the chart.
Indicator threshold
RSI overbought, MACD cross, any indicator vs constant or vs another indicator.
Volume spike
Bar volume exceeds N× the rolling N-bar average.
Order-flow imbalance
Bid/ask delta crosses a threshold within a window. Footprint-quality.
Custom DSL
Any boolean expression in our scripting language, evaluated bar by bar.
News keyword
Fires when a headline mentions a watched keyword for a watched symbol.
Open / close
Session-edge alerts per exchange calendar.
Position TP / SL
Paper or live position hits its take-profit or stop-loss — and auto-closes.
Backtest signal
Replay a strategy and fire when the same signal fires on live data.
Account events
Margin warnings, broker disconnects, fill confirmations.
Outbound channels
- In-app
- Discord
- Telegram
- Custom webhook
- OS push
- Sound
24/7 cloud worker
Fires from a Hetzner / Contabo node, not your laptop. Your machine being asleep doesn't miss the trigger.
Market movers · screeners
Find tomorrow's setup before everyone else.
Each market mover gets its own panel — gainers, losers, biggest dollar moves, unusual-volume leaders, gappers — refreshing every few seconds across stocks, crypto, and forex. The screener stacks any indicator, fundamental, or on-chain metric you want and turns hits into alerts.
Top gainers
Biggest % moves in the session. Per asset class, sortable, click-through to chart.
Top losers
Same shape on the downside. Useful for shorts and bounce setups.
Unusual volume
Symbols trading at N× their average volume. Often the leading edge of a news move.
Custom screener
Filter by indicator (RSI < 30), fundamental (P/E < 15), or on-chain. Save scans. Alert on hits.
News widget · alert-aware
The headline that moves your symbol — surfaced before the candle.
A real-time financial news feed wired into the workspace. Auto-highlights items mentioning a tracked ticker, sentiment-tags each headline, and powers the news-keyword alert category so a Powell mention pages you the second it lands.
Symbol + source + keyword filters
Watch only what matters. Reuters, Bloomberg, CoinDesk, Decrypt, your custom RSS — all in one stream.
Sentiment tag per headline
Bullish / bearish / neutral colouring so you scan a wall of news in seconds, not minutes.
Click → jump to the candle
Click a headline and the active chart jumps to the timestamp. See exactly how price reacted.
Wired to the alert engine
"FOMC" + "BTC" turns into a news-keyword alert. The cloud worker watches the feed for you.
Economic calendar · alert-ready
Macro events on the workspace — and on Discord the moment they print.
A 14- to 30-day forward calendar of every CPI, NFP, FOMC, ECB and central-bank decision. Filter by date window, importance, currency, or free-text search. One click promotes any event into a calendar-event alert that fans out to Discord, Telegram, generic webhooks, email, OS popup, and in-app toast.
14 / 30 day forward window
Worker pulls Forex Factory's weekly + next-week feeds twice daily so you always see two full weeks of macro releases.
Filter by importance & currency
Low / Medium / High importance chips, USD / EUR / GBP / JPY / AUD / CAD / CHF / NZD / CNY currency multi-select, plus free-text search across event names.
One-click event → alert
Pin a Create-alert button on any row. The Time → Calendar alert is pre-bound to that event id — pick an offset (-15 min, -1 h, etc.) and you're done.
Fires to Discord, Telegram, webhooks
Every alert respects the channel routing you set in Notification Channels. CPI prints at 12:30 ET → your Discord trading room gets the ping at 12:15 ET.
The dashboard · your account home
Every trade, journaled. Every alert, in reach. Every metric, charted.
Beyond the chart, Spectra ships a full web dashboard that turns every paper trade into review material. Equity curve, calendar P&L, per-trade journal with screenshots and strategy notes, live alerts, webhook-triggered orders, and tier usage — one signed-in surface.
Overview & calendar
Equity, win rate, monthly P&L calendar, exposure by asset class, and a daily debrief that asks what you did and what you'd change.
Per-trade journal
Notes, plan, lesson, mood and confidence ratings, planned entry / stop / target, tags, and chart screenshots attached to every closed trade.
Alerts you can trust
Active alerts list with the last-triggered time, 30-day fires history, capacity bar against your tier, all the alert kinds the chart can build.
Closed trades, every column
Filterable history of every paper trade — symbol, side, qty, prices, fees, P&L, account — exportable when you want it offline.

I spent six years writing low-level systems code, most of it with a trading screen open on the side. Spectra is the terminal I wanted on that screen: footprint where it belongs, alerts that don't sleep, and a price tag a trader can stomach. One developer, no committee, no enterprise sales call.
Versus the $1,500/year stack
Same tools the pros use. Now free.
Spectra rebuilds every surface that day-trading desks pay top dollar for. Faster. Friendlier. And $0.

The founder
Built by one trader, for traders.
Charbel Alhajj
Founder · Engineer · Trader
Designs, codes, supports, and operates every layer of Spectra Terminal — the Rust core, the native apps, the WebAssembly web client, the cloud workers, billing, and data.
Spectra Terminal is an independent product, designed and shipped by Charbel Alhajj. No investors leaning on the roadmap, no committee tuning the defaults — every decision answers to traders, not to a board.
Six years of full-stack and systems engineering, with the trading screen always within reach. Spectra is the tool that kept getting wished into existence: footprint and DOM on the chart instead of behind a $1,500 paywall, a real scripting language instead of a screenshot folder, and a roadmap shaped by the person who actually trades on it.
You email support, you get the founder. You file a bug, the founder fixes it. You ask for a feature, you talk to the person who decides what ships.
