Commission fee for BF is 5% while only getting 1-3% arbs on average.
I need to know if the 5% is calculated before or after the arb display?
If it’s before it will be a negative arb, causing me to lose money. For example, if the arb is 3% but the commission is 5%, the calcuation would be 3 - 5 = -2
In the example above, I will get a -2% arb before Betfair commission. If this is true, how is this viable? And what should you do?
However, if the arb calculation is done after commission, then everything is okay, the exchange is profitable.
