And the proliferation and increased frequency of data on The Street is further fueling the need for quants in algorithmic trading, notes John Comerford, EVP and global head of trading research at Instinet. For example, "Level 2 [i.e., Nasdaq depth of book] data is about 30 gigabytes a day," he says. "We're dealing with data that's closer to what they deal with in the biosciences and the genomes and not what people deal with in standard relational database technology."
30 gigabytes of data for level 2 only!!!! imagine how many calculations per second you need to be able to browse, scan and make orders based on this database in real time, and the connection you need to the market to be able to deliver this order with the minimum lag. No wonder Spooz changed the office and the connection when testing, and is still making tests with the brokerages. I guess the database will be based at the brokerages offering the service and every client will have access to the assets he is interested in only or it will create a major bottleneck. LOL
