I thought about including the fees, but I felt that would be too many input parameters to adjust, making the tool more unwieldly.  It's easy enough for users to check the fees on their own and subtract them out from the cost and expected payout.

I don't know of Predyx has an API, but a cool thing would be if the user could simply enter the URL of the market and have all the parameters auto-filled.  @mega_dreamer @Team_Predyx

I've recommended they implement something like this for a new mechanism that allows participants to directly input the probabilities they want and Predyx tells them the cheapest way (including sales) to get there.

It doesn't look like fees are taken into account in your tool (maybe they don't matter for what you're trying to do). Something that might be helpful would be a tool that gives the best ROI, based on beliefs and fee structure.
