I optimize using 7 days of one minute data. Each evening at the automatic data update, my one minute data is being deleted. It takes several hours to reload for my 81 symbol portfolio. How can I avoid having to reload for several hours every day?

I copied the following from the data update log:

Deleted Symbols A, ADBE, ADSK, AMGN, AMZN, ANF, BA, BBY, BHI, BMY, BTU, CCL, CHK, CLF, CMG, CNX, COST, DD, DIS, EBAY, EEM, EFA, ETN, EWZ, FCX, FDX, FLR, FXI, GD, GDX, GLD, GME, HAL, HD, HOG, HPQ, IBM, IP, IR, IWM, IYR, JCP, JNPR, KMP, MCD, MDT, MON, MOS, MRK, MYL, NFX, NOC, NTAP, NUE, PEP, PG, QQQ, SBUX, SHY, SLB, SLV, SNDK, SO, SPY, TIF, TJX, TLT, TYC, UNP, URBN, USO, WDC, XLB, XLE, XLI, XLK, XLU, XLV, XLY, XME, XRT

It looks like the log doesn't indicate to which bar scale and provider they belong.

Deleting the data is controlled by the Data Manager option "Delete data fo symbols not included in DataSets". So, unless you requested some symbols on demand w/o them being on any DataSet and then performed Update All Data (by provider) with that option checked, Wealth-Lab would not delete anything.

There's clearly something else to it.

Of course, you can save yourself the pain of starting from scratch by making a backup of the data one you have downloaded it.

It is shown as a data set in my list of data sets. I'll try recreating the set after the market closes.

May have found the problem. I did not set the scale to "Minute" when creating the set. I'll know if that is the problem after tonight's update.
