KKLinePic

Candlestick chart generator

Generate candlestick charts with your real buy and sell points.

KLinePic is a free online candlestick chart generator for traders who want a chart of their own trades — not a blank OHLC canvas. Upload or paste real fills to get a TradingView-style K-line image with entry/exit (B/S) markers, holding window, return, max run-up, and max drawdown on real market candles. No manual OHLC input, no account required.

How it differs from generic chart makers

Real market candles, fetched for you

Generic candlestick chart makers ask you to type OHLC values. KLinePic loads real K-line data around each trade automatically — crypto, US stocks, China A-shares, futures, forex, and MetaTrader.

Buy/sell markers and trade results

Each chart annotates entries, exits, holding window, return, max run-up, and max drawdown, with optional indicator panels such as MACD. It is a trade review chart, not just a picture of candles.

Batch and API

Render one annotated chart per trade for a whole journal in one batch, or automate it through the documented Agent API and CSV/JSON data protocol.

First, get your trade history out of your platform

The export path is platform-specific, but the pattern is similar: crypto exchanges keep executed fills under an Orders or Trade History area with an export button; stock brokers put them under Account Statements or Activity. Pick a date range covering your trades and download a CSV.

Expect three quirks: date-range limits per download, separate exports for spot and derivatives, and timestamps printed in local time without an offset. For venue-specific menu paths, see the guides for crypto exchange exports and broker CSV exports — column names differ by platform, so the mapping below stays generic.

Map your export's columns to the KLinePic CSV

Whatever your platform calls its columns, they map onto the same nine KLinePic fields:

Typical export column KLinePic field Notes
Order ID / Trade ID trade_id Reuse one ID for the buy and sell legs of a round trip so they render as one chart.
Symbol / Pair / Ticker / Instrument symbol Keep the venue's plain trading format, e.g. BTCUSDT or AAPL.
Side / Direction event_type Normalize to buy or sell.
Position side (long/short) position_side Only needed for derivatives (hedged futures); omit for spot and stocks.
Time / Date / Filled at time ISO 8601 with an explicit UTC offset is safest, e.g. 2026-02-28T01:15:00+08:00.
Price / Fill price / Avg price price The executed fill price, not the order's limit price.
Quantity / Amount / Filled / Size quantity Base-asset or share quantity, not quote-currency notional.
Fee / Commission fee Optional; improves net-return accuracy.
Fee currency note There is no fee_asset column — keep the fee currency as free text in note, e.g. fee_asset=USDT, or drop it. Any unrecognized column makes the row fail validation.

From CSV to chart image, step by step

  1. Prepare your trade rows. Each fill becomes one CSV line with trade_id, symbol, event_type, time, price, and quantity (position_side, fee, and note are optional). Anything extra, such as the fee currency, goes inside note as free text like fee_asset=USDT. Give the buy leg and the sell leg of the same round trip the same trade_id so they render as one chart.
  2. Upload or paste into KLinePic. Open klinepic.com and drop the CSV in, or paste the rows directly — no account is needed to render a chart. Exports from the covered exchanges and brokers can be uploaded as-is.
  3. Review the detected trades and pick a style. Confirm each trade sits on the right symbol and candles, then choose a chart style and any indicator panels (e.g. MACD).
  4. Export the image. Download the annotated chart image for a single trade, or batch-render the whole file to get one chart per trade. Watermark-free high-resolution export is a paid option.
trade_id,symbol,event_type,position_side,time,price,quantity,fee,note
T-001,BTCUSDT,buy,long,2026-02-28T01:15:00+08:00,65205.21,0.22,0.92,fee_asset=USDT

Key facts

  • KLinePic (klinepic.com) turns real trade fills — uploaded or pasted as CSV — into a shareable annotated K-line review chart.
  • Charts mark entries/exits (B/S), holding window, return, max run-up, and max drawdown; indicator panels such as MACD are optional.
  • Free to start; no account is required to render a trade review chart. Watermark-free high-resolution export is a paid option.
  • Coverage: crypto exchange fills (Binance, OKX, Bybit, Bitget, Gate, MEXC, KuCoin, HTX), US stock brokers, China A-share statements, futures, forex, and MetaTrader.
  • KLinePic CSV fields: trade_id, symbol, event_type, position_side, time, price, quantity, name, fee, note. Any other column is rejected — extra details such as the fee currency belong inside note as free text.
  • Batch rendering is supported; Agent API documented at klinepic.com/guides/trade-review-chart-api/, data protocol at klinepic.com/docs.
  • The interface is bilingual: English and Chinese.

Common mistakes to avoid

  • Timestamps without a timezone offset. If markers land on the wrong candles, add an explicit UTC offset to the time field, e.g. +08:00 or Z.
  • Quote notional instead of base quantity. Exports often show both a cash value and a filled quantity. The quantity field wants the base-asset or share count, not the cash value.
  • A new trade_id for every partial fill. That splits one trade into several charts. Keep one trade_id per round trip; multiple fill rows under it are fine.
  • Missing position_side on hedged futures. If you hold long and short on the same contract simultaneously, set position_side so the legs are not merged into one trade.
  • Extra columns left over from the export. The parser accepts only the documented fields and rejects rows with unrecognized columns such as fee_asset, currency, or exchange. Fold that information into note as free text, e.g. fee_asset=USDT or exchange=OKX.

FAQ

Is the candlestick chart generator free?

Yes. KLinePic is free to start and no account is required to render a trade review chart. Watermark-free high-resolution export is a paid option.

Do I need to enter OHLC data by hand?

No. KLinePic fetches real market candles automatically — you only upload your trades.

What data can I upload?

A CSV with trade_id, symbol, event_type, time, price, and quantity is enough; position_side, fee, and note are optional, and extra details such as the fee currency go inside note as free text. Fills from Binance, OKX, Bybit, Bitget, Gate, MEXC, KuCoin, HTX, US stock brokers, China A-share statements, futures, forex, and MetaTrader are covered.

Can I generate many charts at once?

Yes. Batch rendering produces one annotated chart per trade in a single run; a documented Agent API and CSV/JSON data protocol cover automated generation.

Why do my buy/sell markers land on the wrong candles?

Almost always a timezone issue: many exports print local time without an offset. Write times in ISO 8601 with an explicit UTC offset, such as 2026-02-28T01:15:00+08:00.

Can I use the generator in Chinese?

Yes. The KLinePic interface is bilingual — English and Chinese.
