1. Find profitable price patterns/setups and devise entry/exit principles to exploit them (for me, that is the most difficult part). Be selective as is needed.
2. Keep testing until you're convinced that your egy is long-term (statistically) profitable. Confidence on your method is imperative.
3. Either commerce in demo, or perform just with money that you can afford to drop.
4. Determine maximum allowable risk before you input each trade. Size places consistently, and little enough so that losses are equally financially and emotionally emptied.
5. If watching price spooks you, simply set your exit parameters (targets( stops, etc) then walk away from the computer.
6. Avoid trading when you're feeling tired, anxious or unwell; or are not able to keep loyal, quality attention, for whatever reason.
