Between it and the book percentages

1. 2 decimal places are not always shown e.g. £9.30 is being displayed as £9.3 currently
2. Negative values in the market book diff table are £-x and not -£x
3. The currency symbol £ is hard coded which may not be correct
4. The string GBP in the total volume matched string is hard coded and may not be correct

• Add the ability to step backwards and forward through a sequence of order books
• Include a play button that will automatically cycle through them
• Default behaviour could be to replay the order books at the frequency they were generated in real-time (using the publish times), and fast forward/rewind controls could speed this up
• Once other visualisations are implemented (e.g. vertical ladders), it should be possible to create a slideshow for any of them

• Vertical ladders are a more traditional way to visualise order books
• These will be on a per runner basis
• For an example of how this is done for Betfair, see Betangel and the runner graph popups on the Betfair website
• It may be possible to display multiple runners alongside each other
• Inspiration can be taken from financial markets (e.g. crypto exchanges) which have more sophisticated front ends than Betfair

Hi Mo

Do you have a sports-data or a POI example to share?

• Will POI get merged into the main branch or kept separate?
• any plans to deal with multi markets or event files?

Cheers

Is there any way to incorporate these visualizations into a Streamlit App?

Allow ingestion of order stream data, either recorded live or simulated based on backtesting results.

• Display executable orders as per website (right hand side)
• Display simulated pnl based on matched orders
• Display orders on ladder view

• One way this could be done is to generate the HTML as is done in the Jupyter notebook, save it to a temporary file, then run the browser and point it to this file

Hey @mberk , thanks a lot for this library. I am using that for personal project and quite curious to see is it possible to also visualize traded amounts?

I am adding one example as attached. We can see traded amounts and also graph which shows how last price traded is changing.

Get the following on install, I assume its because betfairutil isn't on pypi?

It would be great to have a text input to go to a specific minute since the event start (also before with a negative number).

I know that can be achieve with the slider, but i think this way can be handy.

The in-play indicator assumes that all markets turn in play

I've experienced the following issues:

1. Dashboard does not display at all. This seems to be related to the plotly graph. If I remove the graph entirely from the dashboard then everything works. However, I can still create the graph by itself so it's some kind of combination of creating the graph in the context of ipywidgets
2. Slider does not work. This seems to be a problem with using jslink instead of link. See the following issue for a workaround: googlecolab/colabtools#1612
3. Button icons are not displayed. See this issues for a workaround: googlecolab/colabtools#1302
