4. Future and Plans

Algorithmic Trading Platform

• Fast market data and order execution to exchanges throughout the world

• Framework for algorithms written using Scala language

• UI for viewing current algorithm status

• Algorithms were programmed by developers

Algorithmic Trading Platform

The Idea: Broker for algo traders

We want to provide our clients with service that we needed while being algotraders:

• Create algorithms using specially designed simple language in convenient IDE

• Perform algorithm backtesting using historical market data

• Execute algorithms on our servers throughout the world

5

The Idea: Broker for algo traders

• Provide our solution for the clients• We need some additional

components• These components should not

decrease latency, stability and throughput of current system

Erlang OTPFunctional programming language and runtime system

Concurrent processes with async. messages (actor model)Single assignment, dynamic typing

Pros• Designed for distributed systems development• No serialization needed (Erlang terms)• Transparent world-wide nodes (messages and RPC)• Easy monitoring and real-time tracing• Out-Of-The-Box Templates• Other languages integration (C/C++, Java, etc)Cons• Calculations are slow• New development team needed (Risks)

Erlang Benchmarks

• Process spawn time 1.5 µs• Local node message loop delay

• Remote node message loop delay

• Remote node message throughput

We are working on allowing clients to:• Create algorithms using specially

designed simple language• Perform algorithm backtesting using

historical market data• Execute algorithms on our servers

throughout the world
