Issue with Data Download Oanda

| |

Hi,

I have followed steps to setup the needful, set up the "job-user-id" and "api-access-token" keys, data-provider: "QuantConnect.Lean.Engine.DataFeeds.ApiDataProvider" and when run it shows following red message :

ERROR:: ApiDataProvider.Fetch(): Unable to remotely retrieve data for path ../../../Data/forex\fxcm\minute\eurusd

I purchased Oanda historical data and not Fxcm.

Kindly assist.

Thanks.

Your algorithm is probably not specifying OANDA data. If so; please share the algorithm here for assistance.

Your algorithm needs to specify Market.Oanda; e.g.

AddForex("EURUSD", Resolution.Minute, Market.Oanda);

It looks like the engine is trying to decompress a bad file.
Could please checkout the files that were downloaded and see whether they are OK?
You will probably see one or more files with zero size and when you try to open (click on) it, the default software for openning zip files will show you an error. If so, delete this file and rerun Lean. It will download the file again and the issue will be fixed.
If the problem persists, please tell us which the problematic file is.

STAFF ,

A few of those dates might be corrupted & we'll fix them shortly. The others are new years day and christmas eve -- meaning you're probably using an old version of the market hours database. If you update it those dates will be registered as holidays and it won't ask for the data.

Hi, i installed Lean Master on 13-Apr hence should have the latest market hours database ? I have crossed check with the file in Github... May i know how to go about updating the version ?

i resides in Singapore, not sure if there's other settings that i need to do ?

Thanks.
