Why did the Nexa system make the decision it did about this brokers current buy power?
The Nexa system implements business rules that consider many criteria about a broker’s current account and trading to decide whether that broker has sufficient buy power to perform a specific buy. Brokers often call to find out what the buy power calculation was. The Nexa rep will handle this request similarly to the transaction validation above. The only difference is the rep will look for a series of log messages preceding the trade activity for the order ID in question. These will show three buy power calculation messages. Splunk’s View Source link, which shows a selected event in the surrounding stream of events with which it was loaded, lets them quickly spot the calculation messages prior to a trade.
