I have two after market data sources for about 30 instruments.
The first provides data in OHLCV format at minute intervals. While importing data, I also create daily bars by checking the option, "Generate 'Day' bars". This will give me the minute bar data as well as the day bar data.
The next source is daily data in OHLCV format which will be available on next day morning, before start of trading.
My question is:
Will the 'Day Bar' data I import replace the ALL the 'Day Bars' generated from the minute data or only to the extant the data for the instruments for which the minute data is missing? (Will a second Import 'Replace' the existing data?)
Thanks in advance.
