How to Get OHLCV Candlestick Data for a Solana Token

Introduction

To chart a Solana token you need OHLCV bars — call GET /chart/{mint}?type=1h (or use client.getChartData()) and you get timestamped open, high, low, close, and volume arrays ready for TradingView or any chart library.

What you need

• A Solana Tracker API key (free, 2,500 requests/month)
• Node.js 18+

Step 1 — Fetch hourly bars

import { Client } from '@solana-tracker/data-api';

const client = new Client({ apiKey: process.env.ST_API_KEY, baseUrl: 'https://data.solanatracker.io' });
const now = Math.floor(Date.now() / 1000);
const weekAgo = now - 7 * 24 * 3600;

const chart = await client.getChartData({
  tokenAddress: MINT,
  type: '1h',
  timeFrom: weekAgo,
  timeTo: now,
  removeOutliers: true,
});

const bars = chart.oclhv ?? chart.ohlcv ?? [];

Step 2 — Map to TradingView format

TradingView expects time in seconds (UTC), not milliseconds:

const tvBars = bars.map((b) => ({
  time: b.time,
  open: b.open,
  high: b.high,
  low: b.low,
  close: b.close,
  volume: b.volume,
}));

Step 3 — Pick the right interval

Common type values: 1m, 5m, 15m, 1h, 4h, 1d. Use shorter intervals for scalping dashboards, longer for weekly views. Pass time_from / time_to as Unix seconds to limit the window and save credits.

Step 4 — Pool-specific charts

If a token trades on multiple pools, pass the pool address for pool-scoped OHLCV:

const poolChart = await client.getPoolChartData({
  tokenAddress: MINT,
  poolAddress: POOL_ID,
  type: '15m',
});

Pitfall: mixing millisecond timestamps with the API's second-based time field will shift your chart by orders of magnitude. Always confirm the unit before plotting.

FAQ

Does the chart include volume?

Yes — each bar includes volume (and optionally volumeUsd depending on pool).

Can I get market-cap candles instead of price?

Pass marketCap: true in getChartData().

How is this different from the price REST endpoint?

/price returns the latest quote. /chart returns historical bars for plotting.
