Data Feeds

Future Options


The Futures Options data feed is a stream of contracts trades, quotes and open interest delivered to your trading algorithm during live execution. Live data feeds enable you to make real-time trades and update the value of the securities in your portfolio.


The Future Options data feed consolidates market data across the following markets:

  • CBOT
  • CME

Bar Building

We aggregate ticks to build bars.

In live trading, bars are built using the exchange timestamps with microsecond accuracy. This microsecond-by-microsecond processing of the ticks can mean that the individual bars between live trading and backtesting can have slightly different ticks. As a result, it's possible for a tick to be counted in different bars between backtesting and live trading, which can lead to bars having slightly different open, high, low, close, and volume values.


Most live trading algorithms run on co-located servers racked in Equinix. Co-location reduces several factors that can interfere with your algorithm, including downtime from internet outages, equipment repairs, and natural disasters.

Live data takes time to travel from the source to your algorithm. The Future Options data feed has a latency of 20-50 milliseconds. QuantConnect is not designed for high-frequency trading.

Historical Data

When you request historical data or run warm-up, the amount of historical data you can access depends on the resolution of your data subscriptions. The following table shows the amount of trailing historical data you can access for each data resolution:
