While we might directly be able to use these values for Correct Score markets, they're overall not that useful for other markets. We could certainly manually figure them out for upcoming matches but to run a back test on two seasons worth of data, we certainly don't want to be doing this manually for 748 matches. So let's run through how we turn this into something more useful!
Creating Rated Prices
Now that we've trained our model and calculated the probability for each unique scoreline possible for both full-time and half-time outcomes, we'll need to do some additional processing to be able to use these probabilities to bet into the Betfair markets. The next code block will take our model outputs and create rated prices for a selection of markets from the exchange.
This isn't an exhaustive list but it gives an idea of the type of calculation required to transition between modelling and betting.
The next block of code assumes that all required modules have already been imported
Define our markets
Following this we've applied the models to our test set (on which we'll run our simulations) and then generated rated prices for a (non-exhaustive) list of popular markets present on English Premier League matches.
df=pd.read_csv('ensemble_model_results.csv')
'''
The below code will calculate probabilities for each individual market and selection for most markets related to goals scored/conceded
The new column name takes the format that matches the exchange 'marketName_selectionName'

Player markets are not modelled here due to the nature of the dataset but this method could be applied to Cards, Corners and Shots as these fields are all present in our training data.
There are a subset of markets which are only loaded in-play if required (e.g. Over/Under 10.5 Goals) which have been excluded. Markets like Over/Under 8.5 Goals exist but usually contain very little liquidity unless the goal count approaches that value (i.e. scores are unusually high and most volume will come in-play).
Now our model outputs for Arsenal v Leicester look like:
| event_date | fixture | market_name | runner_name | rated_price |

Flumine Simulation
Our next step is to take our results and run simulations on the Betfair Historical Stream Files. These files have a cost associated with them (Australia and New Zealand customers should reach out to us at automation@betfair.com.au to discuss options). We'll use Flumine and its simulation mode to run these tests as these tend to be accurate, and will also help us to test out our string matching against the exchange markets, as this is key to being able to place live bets.
It's important to note that the historic files do not contain cross-matching volume (also called virtual bets) or information from the market catalogue. So just be aware that live behaviour may not necessarily reflect the simulations. Runner information is contained within market_book.market_definition.runners so runner names will be available in the files.
Unzipping The Files
Flumine requires the tar files to be unzipped to run the simulations so we'll iterate over the tar files to extract only the markets we need before commencing the simulation.
We'll quickly process our tar files using our super fast Rust-driven tutorial: JSON to CSV Revisted
By doing so we've created a csv file where we can easily pick out the markets we want to use. (You can skip this step and use the flumine process of check_market_book to filter out unwanted markets)
Market Ids
Market ids in the stream files are denoted by "1.XXXXXXXXX", however in the provided csv file we have removed the "1.".
In excel we do this using the formula: (marketId - 1) * 1000000000
We do this because excel likes to truncate trailing zeros on negative numbers. The python line is provided below
Remove '1.' from market_id in Python
df['MARKET_ID'] = df['MARKET_ID'].apply(lambda x: str(x).ljust(9, '0')[:9])

Here we will specify the folder where we are storing our stream files and where we want to extract the files to
The code will check if the output folder exists, and will create one if it does not.
It will then check the folder and delete any files in the folder that are not tar or csv files
This deletion is to clear any previously extracted stream files and will be much faster than manually deleting them
'''
# Specify the directory where your stream files are stored and where you want to extract the files
source_folder = 'DIRECTORY OF DOWNLOADED FILES'
output_folder = 'DIRECTORY TO OUTPUT DECOMPRESSED STREAM FILES'

except OSError:
pass
Running the Simulation
Now that we've unzipped the files, we'll need to run the simulations on the files.
Just a word of warning: This is not a fast process to run over two years of EPL data. It took my machine with 4 CPUs about 24 hours to pass over this data. The further out from the match start you're looking to place bets, the longer the process will take, as well if you leave bets inplay (using persistence_type="PERSIST") this will also take longer.
The advice here is to use the check_market_book function to not process markets that you're not interested in (e.g. OVER/UNDER_8.5_GOALS, SHOTS_ON_TARGET).
There's a code snippet included after the simulation code that enables you to delete markets that you've already processed so the entire process doesn't need to be restarted if it crashes or needs to be paused.

Conclusion
In this tutorial we've taken our previously trained model, processed the model outputs into rated prices for the exchange markets, unzipped some historical files and run simulations using our rated prices! In Part III we'll take our simulation output to decide what we can use to bet into future markets!
