Nope.
See my earlier post http://finance.groups.yahoo.com/group/amibroker/message/143523
Your solution will plot zero for the first 2 bars when it should be NULL.
If the original poster wanted to keep your structure (i.e. IIF and no pre-assignament of OneHigh, TwoHigh, ThreeHigh), then just change the initialization of ResLine to ResLine = NULL.

I'm assuming that this code correction goes in at line 7? could you please make the correction to the looping sample and re-post? I'd really appreciate it.
