Do you want the "average" price for one bar, or over time?

Metastock Formula Language can be a little confusing, until you recognize that the price variables of H, L, O, C (High, Low, Open, Close) is treated as an "array" -- a collection or group of numbers spread over a time. The time PERIODICITY is specified in the lower-right toolbar: D=Daily, W=Weekly, etc -- each bar can represent a Day, a Week, etc.

In the example you gave, "Highest(C)" would give the largest value for closing price over the entire time period you loaded (something specified in LOAD OPTIONS when using FILE OPEN). It is important to note that this is different vary from the period loaded for Explorations and System Tests -- if they're not the same, the results can be different from what you see on a chart!

For any given bar, you can use these built-in functions (details are in F1 - HELP):

Median Price, or MP(), which is (High + Low)/2
Typical Price, or TYP(), which is (High + Low + Close)/3

Try this:

{* Long-Term Average *}
Periods:=Input("Periods",1,10000,500);
(HHV(C,Periods)+LLV(C,Periods))/2

Do you mean the average of all the prices of the loaded data, or, the midpoint between the highest and lowest data points? They are not the same...

Use LastValue() to make a constant of the data across the entire chart, but be warned the information cannot be used for real life trading without being fully aware of how it works!
