Yes, it is all of that and more. A trader just gotta get good in all those areas and flexible to bend in all those areas. Markets do not "live" by our rules. There are only moments when probable success in a trade is high like 90%. Most of the time if a trader can "see" 60% or 65% probabilty of success he best make haste and place his bets.
Many times probability is only 50% or even less. A trader can still trade the lower probability but will PROBALLY get stopped out more often. However, the times he does get the direction correct ..well..it can make up for all the stop outs.
There is no high level of certainty in the markets, and cannot be, or all who found it would ...well be extremely rich. There are only pressures bull or bearish..up or down..and determining which has the upper hand at the moment is a traders primary task before placing a high probabilty trade. A low probabilty trade can be placed if a trader can read the larger context and interpret it correctly.
Markets have been known to twist interpretations..decisions....stats...into a convoluted mess that has no redemption. That is what stoplosses are for. ROFL
