Easy Language Help

[Michael Harris <eagleinc@xxxxxxxxx>]

Can someone please help me with:

I'm trying to write a SHOWME that will place a mark above every bar
whose high is is higher than the highs of the bar before and after it

and

place a mark below every bar whose low is is lower than the lows of the
bar before and after it.

This is similar to a swinghigh and swinglow.  Thank you in advance.

Mike
