I have seen a tip from somewhere that in order for you to be become successful always in your trading, you have to to a sniper rather than a machine gunner.. If you trade always see all opportunity, every indicator, every momentum, etc. before starting to trade. Don't be hasty to trade every signal day. You just have to find that one trade that can bring you good profits and not painful losses.
I agree with you that we have to keep try ( practice ) to find the best strategy but I'm not see all aspect. Just use technical method ( MA & MACD ) in long term period ( monthly ) and use martiangle money management is enough for me. Never follow other signal but trust my skill only.
