Horizon Software has launched its market data recording and replaying module. The Horizon Replayer allows financial institutions to replay an entire day of market data for a range of asset classes and instruments, including stocks, futures, options, bonds, indexes and ETFs enabling traders to test and fine-tune their algo strategies using real-time data. The Replayer records real-time market data, which can then be replayed at any time, giving traders the ability to analyse, benchmark and test trading strategies using real market conditions, in real-time. Simulated tests can also be run to establish a benchmark baseline for repeat tests. The Replayer allows institutions to reduce the risks and costs of running algos, as well as reducing time-to-market for both new and updated algorithms. An additional feature is being able to provide proof of best execution requirements for regulations such as RegNMS and MiFID. Sylvain Thieullent, CEO Electronic Trading at Horizon Software, says: "The Horizon Replayer is being used for real-time stress testing of trading strategies on the whole list of 50,000 instruments on the Euronext Derivatives exchange." He adds: "This incredibly useful tool is now available to all our clients. If, for example, an algo is not performing as expected, using the Replayer allows the trader to replay the whole trading day and fine-tune their algos, significantly improving performance. We developed the module in response to client requests; Euronext's experience with the Replayer to date has delivered significant benefits." The Replayer works alongside other Horizon Platform functionality, such as algorithmic trading, warrants, delta-one, options trading and market making.
