| } |
| ------------------------------------------------------------------------------ |
| NB: The bit that goes
"Today == Day()" has a double "equal to" sign |
|
| if you want to show the
Previous Day High, Low and Close for ALL days, use this line: |
| Today =
Day(); |
| instead of
"Today = Lastvalue(Day());" |

Someone has posted an Afl in the Amibroker library that uses the
linearry function for real time charting. It will do exactly what I
want but it doesn't draw the lines. Pasted below is the code, does
anyone have a suggestion?
