Relevant to day traders.
OBSERVATION # 1
The greatest number of losing traders is found in the short-term and intraday ranks.
This has less to do with the time frame and more to do with the fact that many of
these traders lack proper preparation and a well thought-out game plan. By trading in
the time frame most unforgiving of even minute error and most vulnerable to floor
manipulation and general costs of trading, losses due to lack of knowledge and lack of
preparedness are exponential. These traders are often undercapitalized as well.
Winning traders often trade in mid-term to long-term time frames. Often they carry
greater initial levels of equity as well.
CONCLUSION:
Trading in mid-term and long-term time frames offers greater probability of success
from a statistical point of view. The same can be said for level of capitalization. The
greater the initial equity, the greater the probability of survival.
