Pascal, if I understand you correctly, your point is that even an intraday robot would need to make exit decisions solely based on a line in the sand (the trailing stop). The question I have is, when would re-assessment of a new entry be done by an intraday robot? Is it not reasonable for an intraday robot not to wait till EOD but determine within a short period of time (after the trade exited) that the next trade provides for a desirable re-entry at the then-prevailing price?
