yes, if person cannot automate then manual trading is needed n lots of practice, either on paper or with real money,
i regularly teach n train programming languages n trading to all my younger cousins who r in school
they all start with 1 lakh on paper, n they must double their money, n then again start with 1 lakh
some go from 1 to 3 lakh in just 1 week, n then again start with 1 lakh
n some keep losing bcoz they dont change n adapt easily
by resetting again n again to 1 lakh, greed and risk remains in control n money management is good
it is all abt discipline n setting fixed rules for profit n loss n then following them
if there is confusion, then person will not follow rules, not take profit , not take loss....
so if u have practiced enough on paper or in real, i would still suggest u to start small
