Incomplete Charts: How to Manually Download Missing Data

During the login process, Optuma checks our servers to determine whether there are end-of-day data updates for your system. If so, then the data will be downloaded automatically. Occasionally data gaps can occur if downloads are interrupted or blocked by security software.


End-of-Day Data

Option 1: Downloading Data for an Entire Exchange from a Certain Date

Note: If data is missing for an entire exchange within the last 2 months, then the following procedure will download the data for all the codes. If the gap occurred more than 2 months ago, see Option 3 below.

1. Log into Optuma and with all charts closed click on the Data menu button and select the exchange to be updated, such as World Indices.

2. Change the Last Date Downloaded to the last bar downloaded or in the case of a gap in the data the day before the gap.

3. Click on Download Daily Data and a progress box will appear in the bottom left corner of the screen.

Option 2: Downloading Data for Individual Codes


If the data is missing for one or two charts, then by clicking on Download History in the Actions panel (or via the right-click menu) an open chart will download the entire data history for that particular code:




Option 3: Import Complete History for the Entire Exchange

If data is missing from more than 2 months ago, then it would be quicker to import the complete historical data for the exchange.

1. Log in to Optuma and with all charts closed click on the Data menu button and select the exchange to be updated, such as Japan Stocks.

2. Click on Import Data History and a progress box will appear in the bottom left corner of the screen.



3. NOTE: This will download the data from our historical data servers to the previous Friday. To download data from the previous Friday see Option 1 above, changing the Last Date Downloaded to the previous Friday.


Intraday Data from a 3rd Party

Optuma is compatible with a number of providers for real-time, intraday data. If data gaps or erroneous spikes occur this can be fixed by right-clicking on any bar before the gap/spike and mousing over the Actions icon and selecting the Clear Cache to this Bar.

This will send a request directly to the intraday provider's servers to refresh the data from the bar that was clicked to the most recent.

Note: If you click Download History a warning will pop up advising that if you continue all your historical data will be replaced, which means you may lose data.
