If a trading system uses max 6 contracts for a total of 20k $ margin maximum allowed (even if it has a buy power of 100k $), if i scale the system down to my 30k $ it scales the number of contracts right?
If i want to trade up to 6 contracts do i have to tell autotrading that i have money that i don’t really have? 
Thx 
Hi Luca,
Yes to both questions.

Does autotrading rounds to upper integer number of contracts?
If yes then i have to set an amount of trading money a bit less than the Buy Power of the trading system, right?
No, it rounds down.
