Market prices from API don't correspond prices from the

Hello there,
I'm learning DDD, (man will I ever actually build an application that works?). I am currently contemplating aggregates, aggregate roots and where they start and stop.
My domain is sports trading with Betfair. I henceforth wish to work with information about sports markets. I gather data about sportsmarkets via Betfair's API as well as other sources...
Lets take a horse race for example. Betfair's market data comes with lots of stuff such as; - A collection of runners (with a whole tree of other classes like price etc) - A venue (a racecource where the race is run.) - An event (for example, the melbourne cup where a bunch of races are run)
Now...when I download market data from the API, it comes as a DTO object graph from one API call... I need to map this to my domain.
I currently have my domain entities independent. No aggregates. (I have a domain entity for a market, a runner, a venue, an event, etc).... However, I have run into problems with the actual implementation of mapping the DTO's into my domain entities.
It seems I have two choices; - I could have a single mapper that maps to an aggregate root (with the market being the root)? - I could have multiple mappers, one for each domain entity, plus one big mapper that does the whole DTO object graph? (The BIG issue here is handling duplicate domain objects. E.g. Mapping runners, each runner will have the same market)
Merging my domain entities into an aggregate I think seems like a good idea. But it seems like it might become a huge aggregate.
I would be super grateful to hear any wisdom or comments on my problem Thank you very much for reading.

WHAT DO YOU MEAN BY A SPORTS BETTING API

API is an application programming interface that is set between two websites to fetch data from the other.

Hello there,
I am attempting to run some indicators on price data provided by betfair's API. I was wondering if anyone could give me any idea or insight on how one deals with inconsitant intervals between observations?
For example presume I have the following price observations (the last one is lagged); 0000ms $3.50 0200ms $3.60 0400ms $3.20 0600ms $3.00 0800ms $2.99 1000ms $5.00 1200ms $8.00 1900ms $8.81
What would you guys suggest one does in this circumstance?
I am inclinded to think the best avenue would be to snap the 1900ms to a 200ms interval, and create artificial observations at the missing 200ms intervals?
I'd be super grateful to hear from anyone who has thought about this stuff before.
Thank you for reading

Hello there,
I am contemplating my architectural choices for consumuing Betfair's api for trading price data...for use in a sports trading application...
I currently, simply use their pull api, where I have a async loop that retrieves the price data every 200ms .... which is simple and works for most things I need to do but it's not ideal. They do have a push api available (their stream api) however I am yet to implement it. It's on the drawing board, but working on my own architecture as a priority.
My current architecture is mostly imperitive. I.e. I got too many loops pulling things around. It seems to me the best way to handle consistant price data and applying algorythmic change is via a messaging system of some variety. The common/maintstream/popular options for doing this I am ignorant of.
As I use DevExpresses' WPF libraries which has a messenger component in it. I have started using that to handle my messenging. However, it occurs to me that perhaps I should be looking at something more generally used than that? (perhaps even just as a learning point for correct architectural decisons)
I was therefore seeking advice as to what products people might commonly use for such circumstances, or any general advice on architecture for this kind of situation.
Thank you kindly for any of your valuable time.

FINAL REMARKS
When you have so many competitors around you with the same business concept, uniqueness and quality are what best decide the fate of your existence. In such situation, not only you need to be extra cautious, but also take every step keeping all your enemies (competitors) in mind.

About me

I have a background in Mathematics and have previously worked in the financial sector and in a supply chain analytics role for a manufacturing firm. These roles were very data driven in nature.
I will work fast and for an affordable price and I can deliver nearly all of this work remotely, so location is not a problem.

What can I do for you?

In a nutshell, I can automate any repetitive task you might do on a computer and, in particular, I can gather, analyse and visualise any data you care for.

Data Collection

I can scrape any website (within the confines of law) and use any API to acquire data. I already have experience and developer accounts set up with several popular APIs including:

• Ebay, Amazon (including access to a Terapeak account)
• Reddit
• Twitter
• Quandl
• Betfair
• Yahoo Finance

Data analysis

Technologies that I am experienced with:

• Python
• R
• JavaScript
• MS Office / Libre Office -- in particular this means Excel and Calc.
• LaTeX

Other languages that I am enthusiastic about:

• Nim
• Golang

Data Visualisation

I can produce data visualisations using the following libraries:

• matplotlib (Python)
• ggplot2 (R)
• d3 (JavaScript) -- this is good for making interactive visuals to display on the web, see here

Scripting and automation

• I can automate tasks in a web browser.
• I can automate gui tasks for desktop programs.
• I can set up automated reminders or trigger tasks at specific times.
• I can write scripts to parse, format and extract data from files.

So what might you hire me for?

Seriously, anything. Let's talk -- even if you just want to someone to bounce some ideas off of.
Here are some more specific examples of things I could do for you:

For your website or blog

• Create nice visuals that tell a story e.g. word clouds, infographics, any time of graph or chart
• Set up analytics services for you website

For your business

• Research your competitors
• Generate leads programatically
• Automate repetitive tasks
• Automate social media tasks.

For your own personal amusement

• I can make you reddit a bot
• Sports analytics -- this is a hobby of mine.

What am I looking for

Remote work would be ideal.
I'm based in London and I recognise this site has an international user base. I'm also genuinely interested in the possibility of working with someone in another country.
Of course, I would be happy to work in person with anyone who is not too far away.
I'm happy to take on ad hoc / one off work but would be pleased to develop a continuous working relationship with anyone that can provide interesting work.
As someone has already asked, I would also consider opportunities for permanent positions.

Sound good?

Leave a comment or send me a pm. :-)
Thanks for reading.
