Implementation of pre-match and Live line

Implementation of pre-match and Live-line in betting

The pre-match and Live line are two key mechanisms in the work of any betting platform. They provide the player with choice, depth and betting dynamics. At the same time, the technical implementation of these lines requires high accuracy, instant response and reliable architecture, especially in live scenarios with thousands of bets per minute.

What is the pre-match and Live line

Pre-match:

• Formed in advance, includes events that will begin in hours or days. Suitable for analytical rates and strategies.

Live line:

• Works in real time, reacts to every moment of the match. Bets are accepted in dynamics, and coefficients are recalculated every second.

Technical Implementation Process

Stage	Pre-match	Live
Getting data	Scheduled events from providers (APIs)	Streaming feeds (WebSocket/Kafka)
Information processing	Calculation of coefficients based on status	Response to live events
Market Formation	Fixed Markets	Dynamic and Time Markets
Update coefficients	At intervals (5-30 minutes)	Every 1-5 seconds
Bidding Terms	Before Event	Live Timeout
Calculation of winnings	After the end of the match	According to the results of live fixing

Architecture components

Feeds - connection to data providers (Sportradar, LSports, Oddin, etc.)
Coefficient calculator - own or provider
Market engine - responsible for the generation of markets and their logic
API server - gives data to clients (web, mobile applications, partners)
Admin - setting up lines, limits, hiding markets
Caching (Redis) - fast response for UI and minimizing database load

What is important for a reliable line

Low latency (especially in live betting)
Stability of feeds and automatic switching in case of failures
Margin control, risk algorithms
Monitoring and logging of each coefficient change
The ability to connect external logic and manual control of markets

User benefits

Wide range of events and markets
Transparency and predictability of calculations
Quick interface update without rebooting
Guarantee of correct bid processing in live

The pre-match and Live line is the core of betting. The success of the project depends on how quickly the platform updates data, how flexible it forms markets and how consistently it can withstand the load in live mode. Competent implementation of the line is a synthesis of technology, data and rates without a single failure.
