can't find metatrader answer

I need to get rid of all the past quotes in Metatrader 4 so that when I open a pair, it goes out and gets all the historical quotes (waiting for update screen).

I thought deleting the history data (c:\program files\metatrader 4\ history\MetaQuotes-Demo\)was it, but the data was still there. I know because I have corrupted data.

Does anyone know the anser?

If my data is tofu I just delete the history folder, MT4 will obviously recreate it, but it should be with new data.

Exit metatrader, delete \history folder, restart metatrader.

If the "bad data" is still there, then you are getting "bad data" from your DemoDealer

It worked. I deleted the data in the sub folders in the history and it worked. thanks guys!
