After doing this for a couple of years, I realize this type of question is almost not worth talking about. And believe me, I used to ask the same questions!!!
Trading is about you, not the holy grail play that no one else knows about...
If your beliefs about the market are different that the creator of a play you will lose money with their plays. If you subscribe to a service you end up taking the plays you think are good not every play. So in effect you are actually trading your own system!!! Ability to handle drawdowns and bad trades in a row also affect each individual trader and system performance.
I have been in Carters room and I think they do a good job of teaching and giving a realistic view of trading. They have one of the best systems regarding market internals. The free market videos they do are excellent.
It is almost impossible to backtest most of the plays in the room, because most are discrectionary and to be taken in conjuction with market internals at the time.
So with pivot plays for instance they become reference points to daytrade off of and some people in the room are fading it and other people are waiting for it to consolidate and buying a breakout pullback type of thing.
Money mgmt for the trades always leave the last 1/3 or quarter discretionary and that portion of the trade is paramount to whether you make money or not at the end of the week. So this is another factor that makes it impossible to backtest and figure out whether the average person is are going to make money with the system..
Overall if you are looking to learn to daytrade or swingtrade futures I believe TTM it is worth checking out.
Just my two cents!!!
