Basically, yes. You can configure most cron programs to mail task output to you (it’s usually done by setting the MAILTO
variable in the crontab, provided sendmail is available on your system).
I use that to do things like:
0 9 11 10 * echo 'lunch with John Doe at 12:20'
It sends me a mail, and I can see the upcoming events with crontab -l
. If it’s not a recurring event, I then delete the rule.
As a trader, I would say this is a minor correction and we really should not read much into it. :) (of course, this is not a financial graph, but I’ve seen the similar patterns of impulse/correction in many graphs that measure opinion and/or human activity)
