Market Data Charting Aggregations TerminalAggregated data services bring the next level of data visualization and analytics. They allow brokers, financial analysis software vendors, and wealth management firms to provide their clients with data services for multiple asset classes using various delivery options. Our services are beneficial for backtesting trading strategies, locating better trading opportunities, or simply delving into the market dynamics using our real-time, delayed, and historical data feed services along with market data aggregations.

Real-time data feeds

Provide better analytics and smarter trading opportunities with valuable data on the current market dynamics from a low-latency stream with candles created on-the-fly. The dynamics are also backed by historical data, reflecting the entire picture of the market situation. 

Historical data downloads

Provide backtesting of trading strategies and historical data collection for analytics with our REST API dedicated to provisions of long time-series of historical candlestick data.

Multiple types of candles

We provide numerous types of aggregations:

  • Tick-based
    Every candle is based on any predefined number of ticks. Traders use them to define possible price movements based on earlier patterns.
  • Time-based
    Every candle is based on a predefined time interval: any number of seconds, minutes, days, weeks, months, or years. They help traders to see the market’s volatility.
  • Volume-based
    Every candle has a predefined volume. They help to identify more precise patterns in the price movement.
  • Price-based
    New candles are accumulated based on individual ticks and built only after the defined price movement happens. They help users to smooth the insignificant price changes and identify the trend more clearly.
  • Price Momentum
    These candles take into account not only price change but also the possible tick size of the instrument. They are more comprehensive and closer to the possible price movements on the market.
  • Renko
    A Renko candle is formed only if the closing prices on the chosen chart time frame moves at the pre-defined value (box size). It is designed to filter out minor price movements to make it easier for traders to focus on important trends.
  • Price level
    The pre-defined aggregate is split into the defined price slices. Such data presentation helps to see on which price level the maximum liquidity was accumulated inside the fixed time interval.
  • Option expiration
    Analysis of the option price trends can be noticed when one option is rolling to the other.
