No, the opposite. You need to be able to trade with uncertainty. Perhaps you meant confidence rather than certainty.
agree....there's chasm between a confident strategy that trades through an uncertain price and having confidence about where price is going.....that chasm can be summed: one is business and the other is gambling
as this is a newbie question requiring a response for newbie readers:
the difference as far as the "need to be right" goes is that you can still smell the coffee and make money with a positive expectancy (forward tested strategy) but you'll puke or oversize very quickly when "certainty" becomes fear
without a proven strategy....most traders who fail do so not because of irregular thinking or poor personal habits (although does contribute) but because they simply dont have a plan, lack knowledge and lack account size....go to any chat room and ask a probing question and see how quickly a definitive strategy is replied, rarely so and it's the distinct (business) reason that many consistant earning traders charge good money to watch their chats, not because they know where price is going but because they can quickly isolate data, appropriate size, know when to sit on their hands and that has nothing to do with some guru prescience which most newbies might think they have...
even a trader who spends way too much time looking at indicators (=once!) can still make an income if they have a forward tested strategy, the difference being rate of return and cost of time....i've seen some top proprietry indicators give false positive signals, yet, the writer still laughs because the strategy simply said to rely on the trade plan at hand and their work has a high win-to-loss ratio.....so, it doesnt matter if youre a DOM player or a swing trader or coin to sser: simply have a trade plan....the need to be right is the need to look good in front of other people and frankly no ones gives a **** if you make a squillion or not because youre not puting it in their account and if you made a squillion without knowing how you did then you'll cough it straight back up again, anyway!
the truth is, most people who blow their accounts simply want to trade want to be in the game, look good, they have no interest in running a business .....
if you want to know if youre speaking to a good trader just ask them to explain recent draw downs and they'll be able to elocute each one on it's own merits and you could call them positive losses because the trader has not veered from the proven plan, the trader simply accepts that there is a win/loss ratio that affects all transactions....the only exception to this conversation is the loss of time employing a plan that requires a dumb turnover to build capital, youre always in the mode of refining the proven plan rather than recovering from no plan at all.....
another thing...philosophical strategy is not the same as actual strategy...this should be fairly obvious, but, truth is, again, go to any chat room globally and you'll find a larger % of talk that is less than strategic and more inline with folk lore euphemisms and gallant urban legends.....they all cook their accounts :-0
certainty cannot be measured in the auction process except in hindsight yet your own reaction to price
is measured (sayings from the gallant urban legends volume 1
)
