Scaling question

I am looking to go automatic on a futures strategy I subscribe to. The developer is trading at 12-18 contracts per trade. I only want to do 1-3 contracts for now. I have contacted C2 and they sent me an article on this. Looks like in the automatic trading setup you can only choose a % for scale. Even in the article they point out that this is not going to work for futures accounts in some cases.

comments please

I would think just doing a 6-17% of 18 lots traded on average would be at
1-3 lots.
And monitor it if you need to trade bigger scale up if he’s trading smaller… best!

Which system are you referring to? You can set max contracts, but if they trade 1, and you scale it, you might not get in on the trade.
