Most people only repeat what they have heard.
If you think about such a statistic for a moment, you will quickly recognize the problems:
- Do we really want to lump serious traders and the Lunchmoney Retail Gang together? This may sound a bit snide, but the problem remains that a trader who feeds an account with 50 USD probably has a completely different attitude to this business than someone who forms a company, hires tax consultants and has a 6-7-digit amount with his broker. Just the marketing of brokers alone is already divided within these extremes and ranges from casino-like to the serious Prime of Prime Broker (if we restrict it to FX). If we were to include all the BinaryOptions gamblers, we would have a market that, for technical reasons, probably produces almost 100% losers.
- The other problem is the time span of the observation and thus the sample size. A short-term trader with a holding time in the minutes produces thousands of trades in 6 months, someone with a holding time of 1-2 months produces only a few.
My conclusion: I wouldn't worry about those numbers at all. The time is better spent working on the traders' mindset and other aspects that define your individual success.
