The primary goal is to identify the theme of the market and consider how best to solve it.
My decision making is based on two basic principles. Marco/micro or inside/outside view
Macro/Outside view
1. Barometer: Bitcoin as the main indicator
2. Collective wisdom: The crowd
3. Cot data: Institution and hedge funds
Micro/Inside view
1. Technical : Chart Patterns and other technical that resonates with your decision making
2. Edge: Advantage with higher probability
3. Money management: How much to risk, stops adjustment, trailing stops, targets, cutting off position etc
4. Knowing yourself: Understanding your strength and weakness
This is the checklist i follow to make decision.
