I will say choose your own way of trading . Any trading system can be profitable for a person who design it ir practiced on it all cannot get same earning from it until they not had enough experience on its advantages or disadvantages. I will advice hard work and spend time in making analysis before you open any position.
3 ducks is a trading system, not an indicator. Search here on BP and you'll find it.It doesn't calculate position, risk, etc, you have to do some things yourself
Please tell me which is the good broker for scalping
My advice for all newbies is to start trading with the Demo account and build a strategy for your future trades. Learn from each trade whether it ends in profit or loss. One more thing, always keep calm and stay away from silly mistakes.
