the fact is:
whether you take care of profit or not, there is three possibles:
1. the market will not give you profit any more, stuck there
2. the market will keep giving you more profit
3.the market will rudely reverse and take away your profit, and if you do not take action, take away more even wipe your out
my wife always asked me about trades. she wanted to buy some stuff in her IRA. often I gave her the right time to buy, she will buy , most time immediately green, she is happy, then I realzied she bought something, I noticed the sell signals, and ordered her to liqidate the holding, she suddenly changed her mind, "no, it is going up, why sell, I want my money doubled". then the funny thing happened, she did not sell. after weeks, she noticed her holdings become red, she started to panic and ask for my suggestion. I said " you are not trading, just investment, you do not need pay attention to the daily ups/downs, just hold on, be patient". she started to frequently check the quotes, login her account and bother me about her holding, worried about the drop. I keep telling her " it is ok to ignore the drop and hold". after months of this struggle, the market comes back, and just I want to tell her to add, she could not wait and dump at the exact entry, see the market shoots like a rocket. then she may try to chase or the bad past horrible experience hold her and concluded :" investment is hard". In reality trading is not hard, just mouse click.
my wife's mistake is she does not know the market, she has no understanding of "TIME is her friend to an investor", the critical mistakes is: do not prepare beforehand, she wants to be a trader to timing or an investor to divendend and captical apprication, how long to hold, when up, what she do, when down, what she do, what indicators/clues/patterns to judge direction/reversal, before she bought her holding, she had no plan at all.
there are no secrets in the market. some market trends, always, just like MDVN, very nicely. FB too

to me, I know the trending market the most, so I just trade trending market. that is my secret.
