There are no missed days in trading
There are only lack of information/knowledge to satisfactory predict near term movements which are 100% predictable.
One should know what the market/instrument MIGHT do tomorrow ,
<b>today.</b>
If you do not know, you have not / can not prepare.
Opportunity + preparation = Success.
Opportunity + blindfolded = "Another missed +200 point opportunity"
Understand this and you will have stepped your game to the next level.
