Working on Pop firms companies

Hello , i wanna know if its allowed to work on a pop firm company like (ftmo , trueforexfunds , …) The thing is i will do analyses for forex pairs cfds . if my analyses are correct on chart i get money if my analyse is wrong i lose nothing because im not using my money so basicly just the account get a negative balance(stop loss). (i know its not allowed to trade CFDS) but here im not trading im just offering my service to the company. so ill be taking positions depending on my strategy . i wont risk any money . Thank you very much … Im so lost .
