01 · The problem

Hindsight is a drug.
It ruins your edge.

Scrolling back on a chart, every setup looks obvious — because you can see the outcome. Real trading happens at the right edge, where the future is blank. That's the muscle Backcandle trains.

FAULT · 01

Backtesting by eye lies

When the next candle is visible, your brain quietly filters out the losers. You remember the wins and call it a strategy.

Live paper is too slow

One trading day per day. Twenty real setups a month if you're lucky. Statistical significance arrives sometime next year.

No journal, no learning

Manual journaling dies by Wednesday. Without logged fills and outcomes, every review session is guesswork.

02 · How it works

Pick. Replay. Trade.
Review.

Four steps, zero setup. Pick an instrument, seek to any date, and trade forward. Every bar revealed is a bar you haven't seen yet. Close the session and your journal and analytics are already written.

01

Pick a symbol & seek

Choose from 38 instruments across futures and crypto perp. Jump to any date in the last 8 years or let Backcandle pick a random day to remove confirmation bias.

Coverage 2017–presentTFs 1m → 1d
02

Advance bar by bar

Manual step with , or auto-play at up to 10×. The right side of the chart is strictly hidden. You feel the tape, not the outcome.

Latency <50 msSpeed 0.5× – 10×
03

Execute real orders

Market, Limit, Stop. Leverage 1×–50×. TP/SL, partial fills, margin, liquidation — the engine prices everything from actual historical candles.

Journal writes itself

Every fill, move, close and PnL update is logged. The analytics view rolls it into win-rate, profit factor, max drawdown, and equity curves across all sessions.

03 · Feature set

Built for the work.
Not the marketing.

No social feed, no "AI signals", no algo marketplace. Backcandle is a single purpose-built terminal: keyboard, chart, order book, ticket, journal. Every feature earns its place.

01 · KEYBOARD FIRST

Live on hotkeys

Built for traders who never touch the mouse.

02 · BAR-BY-BAR

Future stays hidden

The engine strictly refuses to render a candle you haven't paid for.

03 · JOURNAL

Writes itself

Every fill, move and close logged with tags.

04 · COVERAGE

38 instruments

Crypto perps, CME futures, FX, metals. 8 years of history.

05 · MTF

Switch without losing place

Jump between 1m and 1d at the same session time — playhead stays anchored.

06 · ANALYTICS

KPIs you care about

Win rate, profit factor, avg R, max DD — across every session.

07 · RISK

Leverage & liq modeled

Isolated margin up to 50×, real liquidation price, partial fills.

08 · SPEED

Up to 10× replay

A month of price action in an afternoon, smooth even on an old laptop.

04 · Analytics

The numbers that
don't lie.

After each session, Backcandle rolls your trades into a full analytics dashboard: cumulative PnL, drawdown curve, R-distribution, per-symbol breakdown, tag filters. Export CSV or JSON to pipe into any external tool.

05 · Workflow

30 trading days.
One weekend.

Same month of price action. Same strategy. One is live paper-trading; the other is Backcandle at 10×. One will still be running in six weeks. The other is done by Sunday night — reviewed, journaled, improved.

06 · From the desk

What traders say after
a month with Backcandle.

Prop traders, discretionary retail traders, quants prototyping overlays. The common thread: they stopped waiting for data points and started getting them.

LOG · MAR 18 2026★★★★★
I ran 40 sessions over two weekends — more data than I'd collected in three months of live paper trading. My win rate on opening-range breakouts went from 38% to 51%. The bar-by-bar constraint is the whole trick.

LOG · FEB 04 2026★★★★★
The analytics tab forced me to face my profit factor on breakout trades. It was 0.8 — I thought it was fine. I spent a weekend adjusting my TP and got it to 1.6. Couldn't have done that live without waiting months.

Space to play, B/S to fire, arrows to step. I never touch the mouse during a session. The keyboard-first design is rare and it's correct. Would pay double for a DOM ladder.

08 · FAQ

Answers before
the questions.

The things traders ask before their first session — order matching, data coverage, export, sharing, API.

Is this real money?01
No. Backcandle is a pure simulator against historical data. There's no broker, no deposit, no risk. You can't lose a dollar here — that's the whole point.
How does the order matching work?02
Market orders cross the best quoted level at the current bar. Limits fill only if price actually touches them in a subsequent bar. Slippage is modeled from each candle's internals.
Can I export my trades?03
Yes — on Pro and Premium. CSV or JSON, with all fills, positions, PnL snapshots, tags and notes. Third-party analytics tools can ingest it directly.
What instruments are supported?04
Crypto perps (BTC, ETH, SOL, XRP +more on Pro), CME futures, spot FX majors, and metals on Premium. 38 total, growing monthly.
Does it run offline?05
The simulator runs in the browser but pulls historical data from our edge. Historical candles are cached for fast seeking within a session.
How fast can the replay go?06
Up to 10× on auto-play — on every plan, including Free. The render loop uses requestAnimationFrame-batched writes, so playback stays smooth even at full speed.
Can I cancel anytime?07
Yes — cancel from the billing page in one click. Your access stays active until the end of the current 30-day period, then the account auto-reverts to Free. No surprise charges.
Is there an API?08
Not yet on the public roadmap — the platform is browser-only today.
