If you believe the adage that "good trading is boring," then system trading is boring to the nth degree.

There are days, sometimes weeks, that I don't generate an ORDER, never mind a trade. Then there are times when there are so many orders, you have to write them all out first in a general ledger and number the tickets.

On the flip side, system trading is also very peaceful because I'm able to scan thousands of instruments in less than a minute and not worry that I'm missing out of an opportunity. That is a mental advantage if nothing else.
