Backcandle replays real market history bar by bar — future hidden, orders executed, journal automatic. Compress months of paper trading into focused sessions without risking a dollar.
When you scroll back through charts, you already know what happens next. Every setup looks obvious in hindsight and impossible in real time. Live paper trading fixes the psychology — but validating a single edge takes months. A bar-by-bar trading simulator gives you both: real uncertainty, compressed into a weekend.
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.
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.
Manual step with →, or auto-play at up to 50×. The right side of the chart is strictly hidden. You feel the tape, not the outcome.
Market, Limit, Stop. Leverage 1×–50×. TP/SL, partial fills, margin, liquidation — the engine prices everything from actual historical candles.
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.
Chart, order book, tape, ticket — all on one screen, all on keyboard shortcuts. No sidebar ads, no signal feeds, no noise. The render loop is tuned for sub-50ms updates so numbers tick in place even at 50× speed.
Aggregated depth from historical tape, quoted to 0.10–0.50 steps. Bars are pseudo-elements — no layout churn when the book ticks.
Market fills cross actual candle wicks. Limit orders fill only if price reaches them. Slippage modeled from real intrabar ranges.
Trendlines, horizontal levels, boxes and text. Annotations persist per session, per timeframe. Nothing leaks across symbols.
Every price, qty and time uses monospaced digits. Numbers tick without columns jumping — readable at 50×.
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 by making you a better trader.
Space to play, arrows to step, B/S to submit market orders, numbers for qty, L/H/T to draw. Backcandle is built for traders who never touch the mouse.
Manual step or auto-play up to 50×. The engine strictly refuses to render a candle you haven't paid for.
Every fill, move and close logged with tags.
Crypto, futures, FX, metals.
Jump between 1m and 1d at the same session time — the playhead stays anchored.
Win rate, profit factor, avg R, max DD — rolled across every session you've ever run.
Isolated margin up to 50×, real liquidation price, partial fills.
After each session, Backcandle rolls your trades into a full analytics dashboard: cumulative PnL, drawdown curve, R-distribution, per-symbol breakdown, tag filters. Your win rate on breakouts vs. mean-reversion. Your avg R after news events — without spreadsheets.

Same month of price action. Same strategy. One is live paper-trading; the other is Backcandle at 8×. One of them will still be running in six weeks. The other will be done by Sunday night — reviewed, journaled, and improved.
Prop traders, discretionary retail traders, quants prototyping overlays. The common thread: they stopped waiting for data points and started getting them.
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.
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 in live paper-trading 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 — distraction-free is the only way to build real screen time. Would pay double for a DOM ladder.
