What's new.

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 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
• added Start a session anywhere in history: pick the instrument, the date you want to begin at and the balance you want to trade with
• added Step by hand when it matters, or let the market run on its own from quarter speed up to 10× and pause the moment something interesting shows up
• added Skip the dead stretches — jump the session forward without clicking through hundreds of bars nothing happens in
• added Autoplay keeps its own pace even if you switch tabs or your laptop stutters, so a run is never quietly distorted by the browser
• added Walk away mid-session and come back later: the chart, open positions, working orders and your drawings are exactly where you left them
• added Change timeframe without losing your place — drop to 1m to time an entry, step back out to 4h for context, anywhere between 1m and 1w
• added Replay the same stretch of history twice and it behaves identically, so a difference in the result is a difference in your decisions
• added Market, limit and stop orders, each able to carry a stop-loss and a take-profit set at the moment you enter
• added 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
• added 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
• added Scale in and out: add to a position and watch the average entry move, take part of it off and leave the rest running
• added Move a stop or a target on an open position as the trade develops, without closing anything
• added Hedge mode: hold a long and a short on the same instrument at once, each with its own size, entry, margin and liquidation price
• added One-way mode when you would rather a buy simply reduce the short you already have
• added Leverage from 1× to 125×, chosen per side — a long at 5× and a short at 20× can run side by side
• added 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
• added Maker and taker fees charged on every fill, at rates you can set per session — the cost of overtrading shows up in the numbers instead of being hidden
• added 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
• added Nine indicators — moving average, EMA, RSI, volume, Bollinger Bands, VWAP, MACD, Stochastic and SuperTrend — each with its own periods and colors
• added Save the indicator set you actually use as a named preset and put it on any new session in one click
• added Fifteen drawing tools: trendlines, rays, extended, horizontal and vertical lines, channels, rectangles, ellipses, triangles, fibs, freehand brush, text, callouts, flags and a ruler
• added Your drawings stay with the session — the levels you marked before the move are still there when you come back to review it
• added Every closed trade is journalled for you: entry, exit, direction, size, PnL, fees, how long you held it and what closed it
• added Write notes and tag individual trades — the setup you thought you were taking, the mistake you know you made — and leave a note on the session for the plan behind it
• added Filter the journal by instrument, period and outcome, and export exactly what you filtered as a spreadsheet
• added 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
• added 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
• added 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
• added A calendar heatmap of daily PnL, so a bad Thursday habit is visible rather than remembered
• added Set your own rules before a session: a cap on trades, a leverage ceiling, a maximum position size, a daily loss limit and a stop after a run of losses
• added Decide what a broken rule means — the order is refused outright, or it goes through and is recorded against you
• added 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
• added Crypto perpetuals, commodities and US stocks, with the historical candles already loaded and ready to replay
• added Sign in with Google — no extra password to invent or forget
• added 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
• added Upgrade, renew or cancel from the billing page — checkout opens over the app instead of sending you somewhere else
• added Built for the keyboard: step with Space, go long or short with Shift+B and Shift+S, and reach for a drawing tool with a single key
• added Dark and light themes, so the terminal is readable at 2am and at noon
• added Review on your phone — the dashboard, journal and analytics all work on a small screen
