Funding account trading

Assalamu Alaikum

My question is how funding accounts are haram ? We don’t trade on live account it means we are not even trading on live it doesn’t include any transactions of interest and anything. I have contacted many firms it is simulated account and it’s upto them they copy our trades or not. We are just providing data the transfer our data to proprietary firm. We are just providing data to them they are trading on spot or cfd we don’t know that we are getting paid through our skills.
