Trade ticks not matching Aggregates
Aggregates ( OHLCV ) are a little more complex to calculate than just min,max,sum. There are condition matrix tables you must adhere to in the CTA and UTP specifications.

Addition Forex Banks
We have added an additional cluster of Forex banking institutions. Due to adding this, and plans to add more, we have modified the schema of the forex ticks to include the exchange ID. This will be valuable when looking at the prices between forex banking institutions. The Forex schema will be updated April 17, 2018. Since this is a schema addition, and not editing/removing a key, we expect the impact to be low on client application logic. Thanks,

Aggregate Stream Optimizations
We have changed both channels to only broadcast updates on the tickers which have actually had trades in that timespan. Which means the average is ~1000 ticks/second instead of ~8000. This allows better throughput, and less processing messages of tickers that have not changed.

Schema Updates
We are updating the schemas of the TRADES and QUOTES real-time data feeds. All other real-time feeds, and APIs will stay as they are currently. We are changing the schema of the trades/quotes for smaller and only unique per tick data attributes. This will make the messages smaller, enabling less bandwidth and less processing per tick for encoding/decoding the JSON. New schema ticks will start streaming on market open, Monday, January 29th. Current Trade Schema: { sym: 'MSFT', // Symbol sym
