Below I am proceeding on the assumption that if I already have the QMS data with its downloaded values from my source, I could make a new symbol to store this data indefinitely for re-use in backtesting. Then import that data to a new symbol to use it. Also if something goes wrong with my local database, I could re-import that backtest data without having to re-download it.
I have a set of data downloaded from OANDA through QuoteManager, and I made a new symbol to store this data for reuse (ie: "EURUSD_O")
First, I made a symbol to store the new testing data, but then I did not see an option for QMS or Multichart data. So... Since I got the original data from OANDA, I set it to OANDA. Is this right?
Second, I would like to export or otherwise save this data to a home network drive so I don't have to slowly download this again. I try exporting and I notice that there is an important difference between the major export types.
- QMS Export does not allow Exchange Time Zone? Why?
- What is the difference between "Time Expressed In" for ASCII and "Time Zone" in QMS?
Third, when importing the QMS data to my new symbol, it sees that I already have some data from OANDA from the original symbol that matches and wants to know if I want to overwrite. Why would it do this if I am importing to a NEW symbol? Of course, I hit "No", and and the import stops.
All in all, what should I do here to maintain a library of backtest data that is separate from regularly updated trade data that is consistent with time zones, etc? The documentation does not really explain much to me for this.
