This whole discussion all boils down to this:
Do you have realistic expectations about what can be achieved over the long-term when investing or trading?
Some of us do have realistic expectations based on many years of experience in this extremely competitive profession.
Some of us do not have realistic expectations due to inexperience, ignorance, or lack of discipline and psychological self-control.
Which category we (individually) fall into (realistic expectations, or not) today may not be the same as tomorrow or in the future. This is true for us all because mistakes (very costly ones) are always possible at any moment. This is especially true if we (each and every one of us) are not following a business plan and trading plans with diligence and discipline.
Long-term success depends on continuously learning from past mistakes and not remaking those errors in the present tense (here and now). Talking about what you will do in the future is like creating a hypothetical and historical back-test and saying “I coulda, woulda, shoulda be a billionaire by now.”
If you think you can achieve a better long-term track record than Warren Buffet (an unrealistic expectation) than put your money up against him by taking the opposite position of his trades.
C2 has a lot of cons (negative consequences of using the service); especially if you have unrealistic expectations. Every human system has imperfections and limitations.
C2 does have a lot of pros (positive consequences) associated with it if you make prudent and well informed decisions and add the live track record of system performance afforded by C2 to that decision making process. Technology allows us to do things that are impossible without it.
Short-term track records (including few trades over a longer time-span) can be just as dangerous as the improper use of back-test information (hypothetical and historical, not third-party audited in real-time). All probabilistic systems (not 100% certain) have various short-term streaks of winners and losers.
The years you have for experience in this business are inversely proportional to the expected percentage return (annualized) you will think is achievable. The goal is to actually exceed those lower realistic expectations over a longer period of time. It is better to be conservative and careful while still aiming for excellence: this is contrary to being sloppy and careless while taking on unnecessary risk for unlikely rewards.
If it is true that 90 - 95% of us traders lose money and fail and quit than almost all of us have unrealistic expectations.
