@DdIV Unfortunately, there is no easy way to tell what is the type of the asset. Assets returned from Alpaca API all have the "us_equity" class. The only way to distinguish Stock, ETF is from the name field, but the name field doesn't fit into the asset.csv file.

Thanks @kzhao. Unfortunately, that confirms what I thought.

3 ideas for consideration:

• Does the csv file ignore extra fields at the end of each line?
• Does the csv file support "#" comments at the end of each line?
• Perhaps also create a companion AssetsAlpaca[Paper]Name file?

Thanks.

@jcl Is that OK to include a custom column in the AssetList.csv file?

@DdIV I ran some tests. It seems fine to have a custom column in the AssetList.csv. I can add it in the next release.

Thanks @kzhao!

Would it be better as a custom column, or as a "#" comment at the end of the line? (In case @jcl & crew decide to add more columns...)

@DdIV I think it is better to add a custom column. The CSV standard doesn't have a comment.
