Get Solana OHLCV Candles Without Building Price History

Charting starts with timestamp discipline

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.
