We are writing to you as a Vendor who offers a simulation mode (paper trading with no real money) as part of their software offering.
We ask that you make your customers aware that the simulation mode makes real requests for live Betfair data.
This is important from a Data Request charge and an efficiency point-of-view.
It should be made clear that the functionality (like any feature of the software) is offered as a tool to aid bet placement and not intended for long term data analysis.
If customers wish to test strategies, they should instead use the Historical Data services made available via http://data.betfair.com/ or http://www.fracsoft.com – rather than relying on the live system.
This is a much more efficient way for Betfair to provide such data.
