I don't understand why ISX only have about 100K each on license and professional service in H117. Integration usually bring in lots PS. 100K PS revenue is about 50 man days service, or 10 man days per customer which is even not enough for training? how XM generate revenue for ISX? usually ISX should charge XM to customize the API and add additional requirements as report says.
if XM would pay 7m+ to ISX annually, the integration between XM trading system and ISX platform must bring significant professional service revenue to ISX, as it need to implement a lots of XM requirements. watch the PS revenue in coming Q317 as key indicator.
