What I want to create seems very simple in concept, but I am having a difficult time figuring it out looking at tutorials online.
I want to create a Leading indicator that would plot a line for different parameters.
How should I arrange my data to accomplish this? I have the Year, Month, Weekday, Day#, and other strings, parameters I want to plot.
Any help would be appreciated. Thank you.

YEAR | MONTH | Weekday | DAY# | Variablexyz etc. |

In reverse use FileRead{datatype} () function.

Saves all historical bar data (Open timestamp, Open, High, Low, Volume) and every new tick to CSV of your choice.

Thank you for the response. Yes it needs to be in reverse. It needs to read the csv file, and plot the variable values for the corresponding date/time. I'll see if I can't muddle through it and get a simple daily test to work. If it works, when I attach it I should have a moving average in the window with the values for that specific date/time correct?

Is it possible to write an indicator that obtains data from an external text file?
Suppose we have a text file formatted like this:
--
Date1(Tab)Value1(LF)
Date2(Tab)Value2(LF)
...
DateN(Tab)ValueN(EOF)
--
where (Tab) could be actually Tab, or "," or ";" or something else.
How do you make reference to an external file in the source code of your indicator, and how do you make it read the data structured as shown above to show it as a line or bar chart?
Thank you!
