Your post was a thoughtful 1st post.I have bought the Scalpius system after following Scott his mails for about a year. I studied it in detail for a couple of months before taking it to real trading.
I did make my detailed spreadsheets with screenshots and wrote down everything in detail.
I was very enthousiastic because lots of things he says make sense, and I do believe he knows a lot about trading, but...
The system does not work in my experience. I did 60 trades in about a month and a half. It is not profitable. Even if I take out the few mistakes I made, it still was not profitable.
I pay to my broker 5.98 $ per lot commission round trip on a ECN account with FXDD broker.
I compared and finding a lot cheaper with a trustfull broker is dificult.
Even if I make e winner with 1.1R as a benefit and make a loser with as low as 0.8R (in case of the minimum viable R rule he uses ) as a SL, I still am not profitable, because of the commissions of the broker.
In Scott his statistics with his R curve he does not include the commissions, so your positive R curve can go slowly up and you still can be loosing!
Too bad, because this was like the last hope for me that a mechanical system could work. I really was looking for something mechanical for years, but I think for now I don´t believe in it any more.
Anyway I think I learned some things on the way, listening to Scott and other traders looking to alle the videos... I learned stuff, interesting stuff, but not a strategy that works.
So I will keep on studying and trying untill I get there.
Good luck to all of you
Most systems fail because of frictional costs e.g. commissions and selling on the bid and buying on the offer.
Keep at it till you develop an edge which makes money.
