True odds calculator written in Python with a nice GUI. Use this calculator to remove the vig/margin from the bookmaker's odds (use a sharp bookmaker/betting exchange with a lot of liqudity to make sure you have the most accurate odds as possible) and see if you can beat their true odds at other bookmakers.
The methods to remove the margin/vig included in the true odds calculator are:
- EM - Equal margin
- MPTO - Margin proportional to odds (hidden if negative odds are detected)
- SHIN - Shin
- OR - Odds ratio
- LOG - Logarithmic
