Another free alternative is to get futures data directly from the exchange: in the case of ICE Russell 1000 Index Mini Futures (RF) futures, this means the ICE database on Quandl. Data from exchanges is not continuous; instead you will have to concatenate individual contracts by hand in order to generate long-term price histories. Also, many exchanges do not provide backfill and so the depth of history is limited for many contracts.
In order to carry out long-term historical analysis of futures, it is necessary to concatenate various individual futures contracts. Contracts can be concatenated using a variety of roll-date rules (end-of-month, last-trading-day, open-interest-switch) and price adjustments (unadjusted, panama-canal shifted, ratio-shifted, weighted-average). It is vitally important to use a roll rule and price adjustment that corresponds to your use case (trading, back-testing, technical analysis, risk management, economic forecasting) else your analysis will be compromised.
The SCF database provides a wide choice of roll and price rules for paying subscribers. The CHRIS database provides a single roll rule (last-trading-day) and a single price rule (unadjusted). Alternatively, you can build your own continuous contracts with your own custom roll and price rules, using the individual contract data from our exchange databases.
