Most here will concede that the goal of being a successful trader has at least a 90% failure rate. The odds of having a successful trade each time out is 50/50. The only reasonable explanation for this is that there is something else, something extra working against the trader. Some of it, is the commissions that must be paid on every trade. The main problem is that a trader tends to think he/she has figured out something about the market.
Many people begin trading knowing about the 90% failure rate, but begin anyway. Then they conduct themselves under the guise of making their decisions based on "probabilities" and "odds". This is a contradiction.
If they were so ruled by odds, the 90% failure rate would have prevented them from trading in the first place!
The decision to begin trading, and every subsequent trade ever made, is based on a "leap of faith". This is acceptable, but only if it is successful. Obsession with probabilities and odds only reinforces the confidence one has about what they THINK they know about the market. This confidence is the single destructive element in every major trading blowout ever seen. LTCM, Livermore, and on and on..
I did not say that being a successful full-time trader is impossible.
I did say, and reiterate here that someone who is losing consistently should not continue to trade, for their own good.
It is simply another option that these folks should know about, rather than the fallacy that the methods hyped on message boards will turn things around for them. Very very unlikely, which should be telling to one who is not a gambler, that is, who does not bet when the odds are against him.
