"On re-checking plot (re-activating the Hi: and Lo: formula lines),
they do not plot ONLY the highest and lowest values WITHIN that
period (flat lines within periods)."
Lantohsay, with all due respect, you are displaying an inability to
understand a simple & basic logic: there is no software in the world
that can predict future values with 100% accuracy.
A flat line displaying highest/lowest values within that same period
would have to know in advance the High/Low of that complete period,
even before the period came to its end.
Perhaps the "Pivots - intraday" indicator formula at
http://www.metastocktools.com/MACDH/Forex.htm
may be of further assistance to you.
"Moreover, because cross and ref functions are used, N/A values
arise at left-end and right-end of chart."
Yes, it's best not to use any forward referencing in MetaStock code.
A few N/A values at the beginning of the chart do not generally pose
any problem (other than possibly generating some time-consuming
pedantic obsession) - they have little or no bearing to real-world
trading.
Lantohsay, I would suggest that you stick to the originally posted
code to avoid further confusion between the original code and your
amended versions.
