I use it. It is quite good. Signals are quite accurate.
The only thing, in my humble 2 cents, it requires a whole lot of work, as far as for your sheer focus, attention and discipline.
Granted that in general, trading requires these but with this "system", you can see that its winnings depends a whole lot of your ability to control and manage stoplosses.
It is a scalper system. Thus,if you are satisfied and happy with small profits at a time then it is for you. But if you aim to go for a home run, you might need your skill in managing your stoplosses.
Most often, you see that, they move their stops almost immediately once trades are in profit. Trading NQ for example, with this type of fast stoploss moving very close to price movement, you are destined to be whacked out pretty much left and right. You will get frustrated. You will swear up and down and curse up the storm if you don't accept this fact.
