Trade Verification

Overview

Financial organizations with broker/trader operations, managing high volumes of financial transactions, need to monitor, record, log and index transactions to comply with regulations and maintain an accurate snapshot of transaction history. Two problems common to these organizations are requesting history replay and state recovery, both of which are necessary to maintain accurate records and avoid hefty regulatory fines.

The Challenge

Financial transactions stream into the organization at high volumes. Each needs to be verified and documented. The challenge is to capture, copy and index traffic as it enters the system, confirm all trades are fulfilled in the order in which they are placed, and ensure any transaction data entering the system can be easily referenced by all platforms in the organization.

The Solution

Broker/trader operations can use VoltDB as the recovery platform for all transactions received within the organization. VoltDB can be used to record order execution history and to recover state in the event of an application restart. Unlike traditional RDBMSs, each VoltDB execution engine is single-threaded and contains a queue of transaction requests, which it executes sequentially—and exclusively—against its data. Elimination of stalls and associated locking and latching overhead allows VoltDB write operations to complete in milliseconds.

Bottom Line

VoltDB provides execution correctness and trade verification for broker/trader operations in financial organizations, a result not possible with NoSQL solutions, which cannot guarantee transactional correctness.

VoltDB can also be used to search for historical transactions to verify activity, and can publish messages directly from the database, using a third-party connector, to any other platform in the organization.

 


Fraud Detection

Overview/Background

Large multinational banks are targets for many kinds of fraud. Chief among these is transaction fraud, in which a fraudster steals someone’s credit card number or credentials and attempts to charge goods and services illegally. For banks to protect their customers and contain losses associated with fraud, it’s necessary to monitor each card swipe, detect unusual or fraudulent activity, and make an immediate decision to allow the purchase to go through - or to block it as fraudulent.

The Challenge

Detecting fraudulent credit card swipes before a charge is allowed to go through requires moving the fraud detection process from a post-facto, batch decision to a real-time, in-transaction decision before the card swipe is authorized. Latency is a major challenge. Analyzing a card swipe and responding with a decision in minutes takes far too long. Relying on a third-party fraud detection tool to manage fraudulent transactions also can place an organization at risk of monetary loss. Banks need a solution that can ingest card swipe data, analyze it in real time, and make a decision on its validity in double-digit milliseconds. 

The Solution

VoltDB is used to apply bank business rules to a stream of card swipes, hundreds to thousands of times per second. Using stored procedures to manage the analytic logic, paired with state held in VoltDB, banks increase their ability to detect fraudulent cards on the first swipe. As blacklists and rules change, these are uploaded into VoltDB, where the new rules and stored procedures immediately affect card processing decisions.

Bottom Line

Banks using VoltDB are able to reduce fraud risk significantly, increasing their ability to detect fraudulent activity before multiple card swipes occur.

 


Bid & Offer Management

Overview/Background

NBBO is the National Best Bid and Offer, defined as the lowest available ask price and highest available bid price across the participating markets for a given security. Brokers must route trade orders to the market with the best price, and by law must guarantee customers the best available price.

The Challenge

Brokers must be able to provide evidence of compliance with NBBO or risk censure from the SEC. Tracking current NBBO prices of securities, or providing access to the history of NBBO changes on demand to consumers (dashboards or other applications), is challenging with legacy RDBMSs. Legacy offerings do not have the scale, speed and flexibility to ingest vast streams of trading data, analyze the data in real-time for pricing changes, and recommend an action - all within milliseconds.

The Solution

VoltDB can be used to store each market data tick and automatically insert a new NBBO record whenever there is a change to the best available bid or ask price. By maintaining the current NBBO and NBBO history in real-time, broker/trader applications can track routing compliance and slippage in real-time, identifying systemic problems before they create large costs for the institution.

Bottom Line

VoltDB is able to meet the NBBO requirements of broker/trader operations by maintaining real-time fast-changing calculations and enabling real-time compliance tracking and risk management.
