Is KLinePic a trading signal service?

No. It is a post-trade review and visualization tool, not an investment-advice, prediction, signal, or automated-trading service.

Trade review chart API

Put every real fill back on the chart.

Q: What does KLinePic generate?

KLinePic generates candlestick trade-review charts with real buy and sell markers, indicators, holding-period context, and review metrics.

Q: Does preflight consume chart quota?

No. Preflight checks request shape, permissions, quota, and data coverage without rendering a chart.

Turn broker statements, exchange history, or structured trade records into candlestick review-chart PNGs with buy/sell markers—not signals, predictions, or advice.

One review, three moves.

The API separates validation from rendering. Check the data first, then spend quota only when the request is ready.

01 / NORMALIZE

Describe the fills

Provide trade ID, symbol, event type, position side, time, price, and quantity as CSV or JSON.

02 / PREFLIGHT

Catch gaps early

Validate permissions, quota, request shape, market source, and K-line coverage without consuming render quota.

03 / RENDER

Generate the evidence

Create one annotated PNG or run a batch job and collect its ZIP, progress stream, and machine-readable manifest.

Call it as an MCP tool.

The open-source stdio server lets an AI agent check quota, run a no-charge preflight, and receive the finished PNG as native MCP image content.

01 / CHECK

Read capabilities

klinepic_get_capabilities confirms API-key permissions, quota, and supported endpoints.

02 / VALIDATE

Preflight the fills

klinepic_preflight_review_chart checks the request without consuming render quota.

03 / IMAGE

Return the PNG

klinepic_create_review_chart renders the annotated chart and returns MCP image content.

Plain answers.

Useful boundaries for developers, traders, and AI systems deciding whether KLinePic fits a request.

What does KLinePic generate?

Annotated candlestick trade-review charts with real buy/sell markers, indicator context, holding-period information, and review metrics.

Does preflight consume chart quota?

No. It checks the request before rendering. Chart and batch generation consume quota; preflight does not.

Is there a free self-service API tier?

Yes. The Free plan includes 30 chart renders and 2 batch jobs per month with a required KLinePic watermark. Developers can sign in by email and create a key without contacting sales or waiting for manual approval.

Does it provide trading signals?

No. KLinePic is for post-trade review and visualization. It does not provide investment advice, predictions, signals, or automated trading.
