One may feel the need to add discretionary trading to the robot whenever unhappy of its last trade if closed at a loss.

Only to discover that "discretionary fear" caps the robot's gains on its next profitable trade.

I use money management depending on the strenght of the signal, place the new order or update its stops before the market opens each day.

And then I close the robot's account and never open it during the day.

Whenever I have "intraday" doubts, I just watch the robot's equity line and my own: this is enough for me to decide that I won't meddle with it. ;-)
