I think the key psychological assets are:
1) an indestructible belief in the law of large numbers, and its corollary: "the outcome of the current trade doesn't matter the least, as long as it is perfectly executed according to my trading plan / system rules which has a positive expectancy".
2) an indestructible belief that one has done his/her homework, and that this trading plan / system has indeed the best edge the trader could come-up with. As a result, it is futile to try outsmart it on a trade by trade basis.
A by-product of 1) PLUS 2) should then be the ability to remain disciplined and execute according to the plan.
For me, automated trading is a big help wrt to execution according to the plan, as it allows me to literally walk-away from my desk when I feel uncomfortable with the current trade. Not that I interfere any more with my systems' trades, but I sometimes get so distracted by those uncomfortable trades that I can't do any useful work.
Automated trading is also an edge in itself, as it frees-up my day-time for research & developing new systems.
