Crypto Tokens OHLC Candle K-Line API - Real-Time & Historical Price Data

Get real-time and historical OHLC (Open, High, Low, Close) candle data, K-line charts, and price analytics for crypto tokens across all supported blockchains including Ethereum, Solana, BSC, Polygon, and Tron.

Recommendation: Use the Crypto Price API as your main source for OHLC and K-line data—real-time streams and pre-aggregated bars (low-latency, easy to use). When you need full historical OHLC (deep backfill, archive ranges, or candles built from raw DEX trades), use DEXTradeByTokens on EVM or Solana and aggregate trades into candles—see comparison below.

How do I get OHLCV data for a token using Bitquery?​

Use the Crypto Price API first (Trading → Tokens, Pairs, or Currencies): pre-aggregated OHLC, streaming, and intervals such as 1-second and 1-minute, with a clean, multi-DEX index view. For historical OHLC beyond what the Price API covers, switch to DEXTradeByTokens (or chain-specific DEX docs): bucket with Block { Time(interval: { count, in: minutes | hours | days }) } and derive open/high/low/close from PriceInUSD / Trade_Price. See Crypto Price API vs DEXTradeByTokens and the quick table below.

What is OHLC Data?​

OHLC (Open, High, Low, Close) data, also known as candlestick or K-line data, is the foundation of technical analysis in cryptocurrency trading. Each OHLC candle represents price movement over a specific time interval:

  • Open: The first price recorded in the interval
  • High: The highest price reached during the interval
  • Low: The lowest price reached during the interval
  • Close: The last price recorded in the interval

Our Crypto Price API provides pre-aggregated OHLC data with ultra-low latency—use it as the main source for live charts and typical OHLC needs.

Historical OHLC: For deep history or candles computed from raw DEX trades, use DEXTradeByTokens on EVM or Solana (with dataset: combined or archive as needed).

Crypto Price API vs DEXTradeByToken​

Default for OHLC: Use the Crypto Price API as the primary source for real-time and standard OHLC. Use DEXTradeByTokens when you need full historical OHLC or trade-based aggregation over long ranges.

FeatureCrypto Price APIDEXTradeByTokens
Data AvailabilityReal-time + recent OHLC (Price Index)Real-time + full historical (with dataset: combined / archive as supported)
Data ProcessingPre-aggregated and real time aggregation of price dataRaw trades aggregated on-the-fly in your query
Data QualityFiltered, clean price feed, second levelTrade Level Price

When to Use Crypto Price API:​

  • Default for OHLC and K-lines—live streaming and pre-aggregated bars
  • Real-time trading applications requiring normalized pricing
  • Live charting and dashboards with aggregated price feeds
  • High-frequency trading strategies with sub-second updates
  • Limit order execution with reliable mark prices
  • Futures trading and derivatives pricing
  • Lending and borrowing protocols requiring accurate rates
  • DeFi applications needing real-time price oracles
  • Any application requiring reliable real-time price streams
  • Fixed time intervals available due to pre-aggregated data

When to Use DEXTradeByTokens API:​

  • Historical OHLC and long-range backfills
  • When you need actual per-trade detail not only index OHLC
  • Full price history, custom intervals, or archive-backed ranges
  • Any time interval can be used because aggregation is defined in the query over trades

Supported Time Intervals​

Our Crypto Price API OHLC API supports fixed time intervals optimized for different trading strategies:

  • $1,000 USD
  • $10,000 USD
  • $100,000 USD
  • $1,000,000 USD

Choosing the Right Cube for OHLC Data​

The Crypto Price API offers three different cubes for accessing OHLC data. Understanding which cube to use is crucial for getting the right data for your specific use case:

Before we dive into the cubes, let's clarify the key terminology:

Currency - The underlying asset (e.g., BTC, ETH, SOL) Token - Specific implementations of a currency on blockchains (e.g., cbBTC, WBTC are Bitcoin tokens) Pair - Trading pairs between two assets (e.g., cbBTC/ETH, WBTC/ETH, WBTC/SOL)

Currency Cube - Chain-Agnostic Aggregated View​

Use the Currency cube when you want a unified price view of an asset across all blockchains.

Key Features:

  • Aggregates all token representations of the same underlying asset for example for BTC it will combine multiple tokens like WBTC, cbBTC, LBTC etc.
  • Can provide both chain specific and chain agnostic prices
  • Can provide only USD-quoted prices
  • Can combine volume and price data from all chains

Tokens Cube - Chain-Specific Token Data​

Use the Tokens cube when you need OHLC data for a specific token on a specific blockchain.

Key Features:

  • Aggregates across all pairs for that token
  • Can provide both chain specific and chain agnostic prices
  • Can provide only USD-quoted prices
  • Can combine volume and price data from all chains

Pairs Cube - Trading Pair Specific Data​

Use the Pairs cube when you need OHLC data for specific trading pairs on specific DEXs.

Key Features:

  • Pair-specific OHLC data (e.g., ETH/USDC on Uniswap)
  • Can be quoted in USD or quote token
  • Market/DEX-specific data
  • Most granular level of price data

Kafka Streaming for OHLC Data​

For high-throughput applications, use our Kafka streams to get real-time OHLC data:

Kafka Topic: trading.prices​

The Kafka topic delivers real-time, pre-aggregated OHLC data for all supported tokens and currencies.

Schema: Protobuf Schema

Packages:

Kafka Consumer Example (Python)​

from kafka import KafkaConsumer
import bitquery_pb2

# Configure Kafka consumer
consumer = KafkaConsumer(
    'trading.prices',
    bootstrap_servers=['your-kafka-broker:9092'],
    value_deserializer=lambda m: bitquery_pb2.PriceIndexMessage().ParseFromString(m)
)

# Consume OHLC data
for message in consumer:
    price_data = message.value
    
    # Extract OHLC data
    ohlc = price_data.price.ohlc
    print(f"Token: {price_data.token.symbol}")
    print(f"Open: {ohlc.open}")
    print(f"High: {ohlc.high}")
    print(f"Low: {ohlc.low}")
    print(f"Close: {ohlc.close}")
    print(f"Volume: {price_data.volume.usd}")
    print("---")

Kafka Consumer Example (Node.js)​

const kafka = require('kafkajs');
const { PriceIndexMessage } = require('bitquery-protobuf-schema');

const client = kafka({
  clientId: 'ohlc-consumer',
  brokers: ['your-kafka-broker:9092']
});

const consumer = client.consumer({ groupId: 'ohlc-group' });

async function run() {
  await consumer.connect();
  await consumer.subscribe({ topic: 'trading.prices' });
  
  await consumer.run({
    eachMessage: async ({ topic, partition, message }) => {
      const priceData = PriceIndexMessage.decode(message.value);
      
      // Extract OHLC data
      const ohlc = priceData.price.ohlc;
      console.log(`Token: ${priceData.token.symbol}`);
      console.log(`Open: ${ohlc.open}`);
      console.log(`High: ${ohlc.high}`);
      console.log(`Low: ${ohlc.low}`);
      console.log(`Close: ${ohlc.close}`);
      console.log(`Volume: ${priceData.volume.usd}`);
      console.log('---');
    },
  });
}

run().catch(console.error);

TradingView Integration​

Our OHLC API is perfect for TradingView charting. Use our ready-to-use SDK:

TradingView SDK​

import { BitqueryTradingViewDatafeed } from '@bitquery/tradingview-sdk';

const datafeed = new BitqueryTradingViewDatafeed({
  apiKey: 'your-bitquery-api-key',
  token: 'BTC', // or any supported token
  interval: '1m', // 1m, 5m, 15m, 1h, etc.
});

// Initialize TradingView widget
const widget = new TradingView.widget({
  symbol: 'BTC/USD',
  interval: '1m',
  container: 'tradingview_chart',
  datafeed: datafeed,
  library_path: '/tradingview/',
  locale: 'en',
  disabled_features: ['use_localstorage_for_settings'],
  enabled_features: ['study_templates'],
  charts_storage_url: 'https://saveload.tradingview.com',
  charts_storage_api_version: '1.1',
  client_id: 'tradingview.com',
  user_id: 'public_user_id',
  fullscreen: false,
  autosize: true,
});

Advanced OHLC Analytics​

1. Price Change Analysis​

Calculate percentage price changes using expressions:

{
  Trading {
    Tokens(
      where: {
        Price: { IsQuotedInUsd: true },
        Volume: { Usd: { gt: 100000 } },
        Interval: { Time: { Duration: { eq: 300 } } }
      }
    ) {
      Token {
        Symbol
        Network
      }
      Price {
        Ohlc {
          Open
          Close
        }
      }
      # Calculate price change percentage
      priceChange: calculate(expression: "((Price_Ohlc_Close - Price_Ohlc_Open) / Price_Ohlc_Open) * 100")
      # Calculate absolute price change
      priceDiff: calculate(expression: "Price_Ohlc_Close - Price_Ohlc_Open")
    }
  }
}

2. Volume-Weighted OHLC​

Get volume-weighted OHLC data for more accurate price representation:

Note: We include Volume: { Usd: { gt: 5 } } to further remove extreme outliers; the stream already pre-filters outliers—this is an additional check.

subscription {
  Trading {
    Pairs(
      where: {
        Currency: { Id: { is: "bid:eth" } },
        Interval: { Time: { Duration: { eq: 60 } } },
        Volume: { Usd: { gt: 5 } }
      }
    ) {
      Token {
        Symbol
      }
      Volume {
        Base
        Quote
        Usd
      }
      Supply {
        TotalSupply
        FullyDilutedValuationUsd
        MarketCap
      }
      Price {
        Ohlc {
          Open
          High
          Low
          Close
        }
        Average {
          WeightedSimpleMoving  # Volume-weighted average
          Mean                  # Simple average
        }
      }
    }
  }
}

3. Cross-Chain Arbitrage Detection​

Find arbitrage opportunities using OHLC data across chains:

Note: We include Volume: { Usd: { gt: 5 } } to further remove extreme outliers; the stream already pre-filters outliers—this is an additional check.

{
  Trading {
    Pairs(
      where: {
        Currency: { Id: { is: "bid:bitcoin" } },
        QuoteCurrency: { Id: { is: "usdt" } },
        Volume: { Usd: { gt: 5 } }
      },
      limit: { count: 10 },
      orderBy: { descending: Block_Time },
      limitBy: { by: Market_Address, count: 1 }
    ) {
      Currency {
        Name
        Symbol
      }
      Market {
        Name
        Network
        Address
      }
      Price {
        Ohlc {
          Close
        }
        Average {
          Mean
        }
      }
      QuoteCurrency {
        Symbol
      }
    }
  }
}

Run Query ➤

Can I get 1-minute historical OHLC data for a full year?​

Crypto Price API: best for live and recent OHLC; an unbroken one-year 1-minute series may exceed what the Price Index is designed to serve—check your plan and try coarser intervals or DEX-derived data for deep history. DEXTradeByTokens: bucket with Time(interval: { count: 1, in: minutes }) and a 365-day Block.Time range; minutes with no trades will be empty or sparse, and the query can be heavy. Prefer hourly/daily bars or export raw trades for backfill. See Historical Solana aggregate data and DEXTradesByTokens OHLC.

Supported Blockchains​

Our OHLC API supports all major blockchains:

  • Ethereum - ETH, ERC-20 tokens
  • Solana - SOL, SPL tokens
  • Binance Smart Chain (BSC) - BNB, BEP-20 tokens
  • Polygon - MATIC, ERC-20 tokens
  • Arbitrum - ETH, ERC-20 tokens
  • Optimism - ETH, ERC-20 tokens
  • Base - ETH, ERC-20 tokens
  • Tron - TRX, TRC-20 tokens

API Endpoints​

  • GraphQL Endpoint: https://streaming.bitquery.io/graphql
  • Kafka Broker: streaming.bitquery.io:9092
  • Topic: trading.prices

Best Practices​

  1. Choose the right API: Use Crypto Price API as the main source for OHLC; use DEXTradeByTokens for historical OHLC from DEX trades
  2. Choose the Right Interval: Use 1s for high-frequency trading, 1m for standard charting
  3. Use USD Quoting: Set IsQuotedInUsd: true for consistent price comparison
