....Why most of us fail at trading ? ....


By ....most of us....,

which do you mean:

Those learning how to trade?

Those traders wining some, losing plenty?

Those traders winning more than losing?

Those traders winning consistently over a period of time?

FOR THE LEARNING HOW TO STAY ALIVE GROUP:

Mostly they fail to succeed because not finding the right tools
and setups as yet; akin to trying to lobotomize with linen table knife!

FOR THOSE WIN SOME, LOSE SOME GROUP:

Mostly failure dues to inconsistency in executing trades
according to setups and plans, even though their tools of
trades should be profitable, but they perhaps, just carry
too many self-doubt, emotional and psychological
hangups with extended physical fatigue. IN TRYING TO TRADE
FROM BEGINNING BELL TO CLOSING GONG.

FOR THOSE CONSISTENTLY WINNING MORE THAN LOSING GROUP:

Mostly are consistently unable to carry out own goals and objectives,
trying too hard to stay on winning trades too long, wishing
and hoping that those winning trades will ascend or descend
to personal stops; without giving enough respect to the
ever changing market buying selling factors; and/or

applying the same profitable tools and setups in the
earlier session, to the changing and different market
buying selling forces/factors in latter hours; erroneously wishing
and hoping for the market forces to remain favourably
unchanged.

SUMMARILY, consistently profitable traders will apply different
tools and setups to ever changing market conditions with an
open eye on their own physical, mental and psychological
limitations; namely, refrain from trading from opening bell
to closing second, like so very many avid traders believe and advocate!

Believe what you may, and
trade what you wish with
whatever tools and setups you love;
no worry, no hurry, margin calls
is just waiting around the corner,
confound it.

My humble apology for rambling on so long. Many would
have more to augment with even more substantively
info and contributions.

Profitable trading to everyone.
