What is Arbitrage?
Arbitrage bet in sports betting is an activity where you simultaneously place bets on all possible outcomes of an event at odds that guarantee profit, whatever the result of the event will be. A simple example of how this can be achieved is found here.
Getting a betfair API key
In order to use the Betting & Accounts API, you need to have an Application Key. The Application Key identifies your API client. Two App Keys are assigned to a single Betfair account, one live App Key and one delayed App Key for testing. The delayed API key will give a delay on all odds feeds from the listMarketBook operation. This script can be used using only the delayed API key, however red herrings's may appear, and arbs may be missede due to the delay in the feeds.
To obtain a betfair API key, you must first create an account on Betfair. Once this is done:
- Log in to your Betfair exchange account (make sure to do this first).
- Go to the Accounts API Visualiser and ensure the the Endpoint "UK" is selected.
- Select the createDeveloperAppKeys operation from the list of Operations on the top left hand side of the visualiser.
- Enter your Application Name (this must be unique) in the 'Request' column. The Application Name can be any name of your choice, but like your Betfair username, must be unique.
- Press Execute at the bottom of the 'Request' column.
- Two Application Keys will then be created and displayed in the Developer Apps column of the demo tool.
You will only need to create an application key once. See here learn more, and to find out about activating the live API key
How to use the script?
Dependencies:
- urllib
- urllib2
- json
- requests
- BeautifulSoup
- Pandas
- unicodedata
- numpy
- pytz
- sqlite3
To use the script, you will first have to fill out the betfair/userinfo.py file. It should contain your Betfair username, password, and API key from above.
Provided this is done and all dependencies are installed, the bot should run infinitely (until stopped) by simply running python master.py.
It will return arbitrage opportunities in the form of:
We will get 5% ROI if we bet 70% on N Djokovic at 1.5 and 30% on R Nadal at 3.5
(Info as to which book each odds are available at will be in the next commit)
This means that if you are betting €/$/£500, you should bet 350 on N Djokovic and 150 on Nadal, to get a guaranteed profit of €/$/£25.
Disclaimer
This is intended purely as an experiment and it is not recommended that anyone pursue the alerts provided by this script with their real money. I will not be devoting any time to maintaining this bot, and as such bugs can creep in which can challenge the authenticity of an arb. Combined with this, arbitrage is a risky endeavour even with a perfect alert service. I repeat the earlier mantra: do not practice this with money.
