@DdlV You can use the Download script. In the first input box, replace the Symbol with the generated asset file name (without the .csv)

Thanks @kzhao. But I don't understand. How does this help create a subset csv containing only those Assets with <n> History values?

Thanks.

@DdlV I see. I misunderstood your question. Do you want to create a .csv file containing the history values of all the symbols in *symbols? I'm afraid Zorro doesn't provide this functionality. But you can use the ZHistoryEditor (http://server.conitec.net/down/ZHistoryEditor.zip) to create .csv file for each symbol from the .t6 file then combine them to a single .csv. Hopefully, this helps.

Thanks @kzhao. Sorry for not being clear. I'm looking for a way to query "How much History does this Asset have?" without actually downloading the History at that time.

Example scenario: I get a list of Assets (stocks and/or ETFs) for some sector. I'd like to quickly prune the list, eliminating any Assets that don't have whatever I consider to be enough History. I.e., I don't want to waste the time downloading what won't be enough History for Assets that I won't consider further.

Thanks.

I know zero broker API's that give you this information. Really, the only way to know this is to download historical data.

@DdlV

As @AndresAMD said, Alpaca doesn't provide any API to give you this information.

Thanks @AndrewAMD, @kzhao.

I didn't expect, but I hoped...

Oh well, off to devise yet another workaround...

Thanks.

Hi @kzhao,

I'm not sure if this is a plugin or Zorro issue... Very occasionally (like 1x/mo at most) when I'm downloading prices and there is an extended or more severe Internet outage, Zorro will hang hard. The message window stops updating, clicking Stop does nothing, and clicking Close does nothing. I have to kill Zorro completely. Have you seen this? Or is it a Zorro issue? Or Windows?

Thanks.

@DdlV Hmm, I haven't seen this yet. Not sure if it is a Zorro or plugin issue. Both are possible. I'll keep an eye on this. If you have a log with the log level set to 6, that could be helpful.

@kzhao,

Have set log level 6. Will let you know what it shows when/if happens again.

Another question: If I use



to get a csv of all symbols, is there an easy way to tell what's what? Stock, ETF, or other attributes?

Thanks.
