Analysis of High Frequency Data

Hi All,

We did some analysis on High Frequency Data (not available for retail traders) where data comes in every 2-3 microseconds (1 millionth of a second).

Just to give some perspective

  • Each day close to 1 TB of data is generated by the exchange
  • Data is disseminated across almost 30 IP addresses
  • The total bandwidth required is 10GBps (normal house internet is max about 300 mbps - some have 1 Gbps)

So what can we say about intraday trading ?

  • Profitable trades occur only in 20% of market time. So in essence - if your in market time where your positions are generating PNL is more than 20% of your investment horizon, you need to relook at your strategy

  • Roughly direction of market is determined in time steps of 120 microseconds - so for a trend to develop - it takes within a second - whereas market data comes in 1 second intervals for most retail trading platforms

Anyways - it takes years of development and fantastic technology professionals to build a platform that can handle such speeds of data. Hence so rare.

Is ‘HFD’ in any way useful for retail traders?

Yes ofcourse. Being retail just means you are not an institution - but you can trade it if you are able to process it and work with a broker who has colocation servers deployed.

What’s the use case?

Thats for you to research :slight_smile:

Let me guesstimate (don’t have the opportunity to analyse). HFD is unusable for the discretionary retail trader. And not of much consequence even for the retail algo trader.

Yes absolutely useless for discretionary trader

For retail algo traders - I think quite difficult if not impossible - as someone who has the computational infra to process is most probably not going to be a single person trading - more of a team with multiple competencies.

That said, any group of people as AOP or LLP want to trade - will still be classified as a retail trader. Typically institutional trader means financial institutions.
