Backcandle 2.1 — a softer, clearer look on every screen

A fresh coat across the whole product: a mint canvas with white rounded cards, a teal accent and new type, in a light theme and a matching dark one. The terminal now fits a laptop, a tablet and a phone without cutting anything off, popups open faster on machines without graphics acceleration, and your discipline score on the progress page shows how your recent sessions went at a glance.

added 1

Your discipline at a glance on the progress page: the average score of your last five graded sessions and how it moved, one tile per session that opens it in the journal, and your run of perfect sessions

changed 4

A new look across the terminal, every app page and the public site: a mint canvas, white rounded cards, a teal accent and soft depth instead of hard frames
New type: Bricolage Grotesque for headlines, Plus Jakarta Sans for text and DM Mono for prices and figures
Both themes redrawn — a light one by default and a matching dark one
A new logo: "back" with "candle" on a mint highlight, and a "bc" icon in your browser tab

improved 6

The terminal fits every screen: on a laptop or tablet the player folds its buttons to icons and the top bar drops labels instead of pushing your balance off the edge, and on a phone the symbol is shown in full
The session status leads the player bar — a coloured dot and its state: active, paused, completed or abandoned
Order and position notices appear as a small card under the top bar, with the time and whether it went through
Popups and the margin form respond faster on computers with graphics acceleration turned off, and lite mode now drops every soft shadow
On a tablet, the dashboard's today's sessions, the top sessions in analytics and your billing history show as cards instead of tables that ran off the screen
Journal rows stay on one line on a tablet, and the session length on the dashboard sits in its own pill next to the date

The "Picked" tag on the instrument you chose when starting a session — the highlighted card already says it

Backcandle 2.0 — a new look, blind replay, challenges and shareable results

Backcandle has a new look: the terminal, every app page and the public site now share one design, with Paper as the default theme and Graphite as its dark twin. Underneath it there is more to practise with — replay blind without knowing the market or the dates, take on challenges with a pass mark and a leaderboard, try a session without an account, and finish every session with a report card you can share.

added 19

Paper is the new default theme, with Graphite as its dark twin
Blind replay: Backcandle picks the market and the dates and hides both until the session ends, so you trade the chart in front of you, not what you remember about it
Try a replay without an account — one free session from the landing page or any historic day; sign in with Google afterwards to keep it, otherwise it is cleared after 48 hours
30 historic market days to replay — crashes, rulings, halvings and squeezes — each written up with what made it hard to trade and one click into the session
Challenges: fixed scenarios with a pass mark — finish green, keep drawdown under a limit, hold your discipline score — graded automatically the moment the session ends
The 10% Week: seven blind days on Bitcoin, Ethereum, Solana or XRP, with a fresh window on every attempt
Challenge leaderboards ranked on each trader's best attempt, under a nickname you choose in settings — or as Anonymous
A progress page: your streak, active days, the trend of your discipline score and badges for milestones from your first session to ten passed challenges
Add or remove margin on an open position to move its liquidation price without closing the trade
Hover a trade marker on the chart to see the trade behind it
One-click risk rule presets when you start a session — pick the commitments you are making and the report card holds you to them
A report card when a session ends: your discipline score, every rule you kept or broke linked to the trade it happened on, and one thing to work on next time — with a button straight to the session's journal
Share a finished session: a public page with the chart, every trade and the result, and a link you can revoke whenever you like
Free now covers Ethereum, XRP, Solana, Apple and gold alongside Bitcoin
A warning in the app header when your paid access is about to end, and an email three days before it does
Emails for the moments that matter: a welcome, access granted, access about to end and access ended
A blog: fifteen posts on backtest statistics, risk and trading discipline
A keyboard map with every shortcut the terminal knows
Side-by-side comparisons with other replay tools, with a source and a date for every claim about them — or "not verified" where nobody checked

changed 3

A new look across the whole product — the terminal, every app page and the public site share one design: hard frames, plain type and status colours you can read at a glance
A new logo: the BACK | CANDLE stamp
Plans are one-time payments for 30 days or a year — nothing renews; buy the next period whenever you like and it starts when the current one ends

improved 10

One menu in the app instead of two — every section, settings, billing and sign-out in a single side menu that also opens as a drawer on a phone
The dashboard, journal and analytics read better on a phone — today's sessions show as cards instead of a table you had to scroll sideways
The position card has Manage and Close buttons, and open positions page one at a time instead of stacking up
Funding and its countdown sit in the top bar, next to balance and equity
Cancelling a limit order removes it at once
Every instrument and session length is on the new-session page; the ones your plan does not include are greyed out with the plan that unlocks them
The journal shows the timeframe, session length and return on every row, the gross result behind the net one, and your session note beside the dates
Sessions that ended without a trade can be shown in the journal when you ask for them
Abandoning a session now says plainly that it will not reach your journal
Dates and times are shown in your own timezone

fixed 1

Signing in returns you to the page you were trying to open instead of the dashboard

removed 1

The cancel button — with nothing renewing, there was nothing for it to cancel

Feature

launch

Backcandle 1.0 — trade real market history, bar by bar

The first major release. Pick an instrument and a point in history, then step the market forward one bar at a time with the right side of the chart hidden — you trade what you can see, never what already happened. Positions behave like the real thing: leverage, margin, funding and liquidation all cost what they would live. Every closed trade is journalled on its own, so a session ends with numbers on your execution instead of a vague feeling.

added 40

Replay real market history one bar at a time, with the right side of the chart hidden — you can only trade what a trader standing at that moment could have seen
Start a session anywhere in history: pick the instrument, the date you want to begin at and the balance you want to trade with
Step by hand when it matters, or let the market run on its own from half speed up to 10× and pause the moment something interesting shows up
Skip the dead stretches — jump the session forward without clicking through hundreds of bars nothing happens in
Autoplay keeps its own pace even if you switch tabs or your laptop stutters, so a run is never quietly distorted by the browser
Walk away mid-session and come back later: the chart, open positions, working orders and your drawings are exactly where you left them
Change timeframe without losing your place — drop to 5m to time an entry, step back out to 4h for context, anywhere between 5m and 1d
Replay the same stretch of history twice and it behaves identically, so a difference in the result is a difference in your decisions
Market, limit and stop orders, each able to carry a stop-loss and a take-profit set at the moment you enter
Stops and targets belong to their position: close it and they go with it, so nothing is left working on the book behind your back
Nothing fills on the candle you were looking at when you clicked — market orders fill on the next bar, resting orders only once price actually reaches them
Scale in and out: add to a position and watch the average entry move, take part of it off and leave the rest running
Move a stop or a target on an open position as the trade develops, without closing anything
Hedge mode: hold a long and a short on the same instrument at once, each with its own size, entry, margin and liquidation price
Layered exits: rest reduce-only take-profits and stops on part of a position and let the rest run
Leverage from 1× to 125×, chosen per side — a long at 5× and a short at 20× can run side by side
Isolated margin and liquidation modelled on Binance USD-M futures: get liquidated and it costs you the position's margin, exactly as it would live
Maker and taker fees charged on every fill, at the rates you set, fixed for each session when it starts — the cost of overtrading shows up in the numbers instead of being hidden
Funding on perpetuals settled every 8 hours from the real historical rates, with a countdown to the next payment so an overnight hold is priced honestly
Nine indicators — moving average, EMA, RSI, volume, Bollinger Bands, VWAP, MACD, Stochastic and SuperTrend — each with its own periods and colors
Save the indicator set you actually use as a named preset and put it on any new session in one click
Fifteen drawing tools: trendlines, rays, extended, horizontal and vertical lines, channels, rectangles, ellipses, triangles, fibs, freehand brush, text, callouts, flags and a ruler
Your drawings stay with the session — the levels you marked before the move are still there when you come back to review it
Every closed trade is journalled for you: entry, exit, direction, size, PnL, fees, how long you held it and what closed it
Write a note on any trade — the setup you thought you were taking, the mistake you know you made — and one on the session for the plan behind it
Filter the journal by period and instrument, and on Premium export a session's trades as a CSV
Win rate, profit factor, maximum drawdown, average win and loss, expectancy in R and an equity curve — for a single session and across everything you have traded
Risk-adjusted numbers when the averages are not enough: Sharpe, Sortino, Calmar, value at risk, your longest winning and losing runs, and your biggest single win and loss
Find out when you trade well and when you should stop: breakdowns by hour of day, day of the week, how the trade ended and how long you held it
A calendar heatmap of daily PnL, so a bad Thursday habit is visible rather than remembered
Set your own rules before a session: a cap on trades, a leverage ceiling, a maximum risk per trade, a daily loss limit, a stop after a run of losses, a required stop-loss and no averaging down
Decide what a broken rule means — the order is refused outright, or it goes through and is recorded against you
Finish a session and get a discipline score out of 100, with a rule-by-rule account of what you kept to and every breach that got past you
Crypto perpetuals, commodities and US stocks, with the historical candles already loaded and ready to replay
Sign in with Google — no extra password to invent or forget
Free, Pro and Premium plans covering how much you can trade in a day, how many sessions you can keep open, which instruments you can reach, and how deep the journal and analytics go
Upgrade, renew or cancel from the billing page — checkout opens over the app instead of sending you somewhere else
Built for the keyboard: play and pause with Space, step with →, go long or short with Shift+B and Shift+S, and reach for a drawing tool with a single key
Dark and light themes, so the terminal is readable at 2am and at noon
Review on your phone — the dashboard, journal and analytics all work on a small screen
