Candlestick chart generated from a trade CSV with buy and sell markers — Example output: real BTCUSDT candles, buy/sell markers, and the realized P/L path — generated from two CSV rows.

How it differs from generic chart makers

Real market candles, fetched for you

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

Buy/sell markers and trade results

Each chart annotates entries, exits, realized return, holding period, and max drawdown. It is a trade review chart, not just a picture of candles.

Batch and API

Render one annotated chart per trade for a whole trading journal in one batch, or automate generation through the Agent API and MCP server.

Three steps from CSV to chart image

1. Prepare rows with trade_id, symbol, event_type (buy/sell), time, price, and quantity — or upload a broker/exchange export directly. 2. Review the detected trades and pick a chart style. 3. Generate a single PNG or a ZIP of every trade.

FAQ

Is the candlestick chart generator free?

Yes. You can generate watermarked candlestick chart images for free without signing up. Watermark-free high-resolution images are available through credit packs or subscriptions.

Do I need to enter OHLC data by hand?

No. Unlike generic chart makers, KLinePic fetches real market candles for crypto, US stocks, A-shares, futures, and forex. You only upload your trades — the K-line data around each trade is loaded automatically.

What file formats can I upload?

A simple CSV with trade_id, symbol, event_type, time, price, and quantity is enough. Broker statements, Binance/OKX/Bybit exports, MetaTrader history, and backtest logs are also recognized automatically.

Can I generate many charts at once?

Yes. Batch generation renders one annotated candlestick chart per trade and packs them into a ZIP. There is also an Agent API and MCP server for automated chart generation.
