You can't change the TimeFrame to a lower value than your database,
which is EOD. The only part about Mixed EOD/RT is that it allows the
current quote (apparently every 5 minutes in your case) to take the
place of the current EOD value. So, you have no data smaller than daily
bars and you cannot change the timeframe to a value less than 1 day.

| you need to follow the examples and information that is provided in

| You need to get the data back to teh base time period, then expand the

|
| timeframeset(indaily);
| avgvolume=MA(V,30);
| timeframerestore();
| addcolumn( timeframeexpand( avgvolume, indaily, expandlast) ,
| "avgvolume");
|

| data in the same database causes any problems, as the eod is given a
| timestamp of 11:30pm I believe, and his could overlap the intraday
| times depending on your location and market. I keep them in separate
| databases so that they do not interfere with each others values
