Refreshing chart with imported ascii data

I frequently need to update a dde instrument with ascii data.

Clearing the cash and reloading data does not update a chart with the new data, the only way seems to be to close and reopen MC.

Is this to be expected.

jl12, have you tried reloading the chart ?

Yes I have use reload and closed and opened the chart

jl12, how do you actually "update dde instrument with ascii data"?
What are the exact steps you do? Are you importing the data into dde instrument or using merging?
