Quote from short&naked:
travis, indeed, the order of the factors up for discussion is paramount. As is the order of the general factors of trading that one should consider. Let me therefore propose a possible order that the three elements of trading might be grouped into (in order of consideration).
1. Money Management (risk profile and equity): I would submit that one's risk profile and approach to money management should come before all other considerations. The relation of equity to order size to stop size should be determined first. As we discussed, if order sizes are small relative to equity, psychology will play less of a role in trading. If, in addition, stops are placed further away from a position (while still keeping order size low), a trading edge could be quite dull and still be profitable in the long run. Traders with less capital can often compound nicely without the need for day-trading or taking large risks.
In short, the questions that should be answered here are: How much capital do you have to trade? And how much ROI do you wish to receive on that capital? Once these goals have been set, we can move on to the technical aspects of trading to fit the profile we have just specified,
2. Edge: This is where we determine whether to go with a discretionary or automated approach and whether short-term or long-term trading should be implemented. Again the sharpness of an edge depends on ROI goals and the risk profile specified above. The possibilities here are almost endless as there are many approaches that can be taken there. The goal should be to find an edge that lasts as long as possible given a particular risk profile. At this point paper trading and back testing might come into play and developing an edge.
3. Psychology: Once the risk has been set and we have determined to a profitable edge (either via automated or discretionary trading), we can determine how much time should be spent on psychological considerations. In many cases, this issue will be come almost mute. If the strategy chosen is rather aggressive and discretionary, some mental hardening might be necessary. However, in most cases, dealing with these issues in the beginning is a waist of time, since this issue usually ends of taking care of itself.
I therefore think that putting a percentage relevance on each factor is less useful than the order of their consideration. And in the end, it is only logical that psychology finds its place at the end of the list. Once the order of the above three has been fixed, then their relevance can be determined.
A laboratory posting at best with no relevance to real trading despite all appearances.
