Yes you are right, big money is made by a few monster trades.The reason traders fail to make money , is fail to capitalise on these trades. Now the question is why do traders fail to capitalise on such winning trades?
The answer to this question is the path taken by these monster trades? Now if you observe any monster trades in a 5 minute chart , you can see countless moves opp to the main direction. Now the question is what do these counter trend moves does?
The answer to the question is those counter trend moves eat away your profits already earned in that trade.which is unacceptable and painful.
This makes the path of earning wealth tricky, in the sence that a traders unwillingness to part with his profit is actually depriving him of more profits.
So i conclude that the successful trading is very painful and human tendency is to avoid pain.This makes trading against human nature.
Just my 2 cents....
there are only 2 ways to trade for me...
long by buying the retracement... in case of trending market
or
long by fading extreame... in case of bracketed market...
vice versa for short side...
One has to shift gear accordingly. There is a frame work of support and resistance based on how bigger traders are positioning themselves. Only way to make money is to align with them. No point shorting a scrip just above known support. likewise, taking a buy signal just below a known resistance is not going to help my odds.
Then comes the mindset part. As intraday trader, i know i wont catch the monsters. Sometimes, i might get lucky and a big one might survive my aggressive trailing. But I know my style of trading and i know my weakness. I prefer small stoploss and RR of 2+. So i play to my strength.
Good amount of money is made in the market with common sense trading only. Knowing the market, knowing oneself and knowing how to manage a trade.
