Any chance you can add a Coinbase feed to SC feed? Thanks

Coinbase appears to be available as a data source from bitcoincharts in several different local currencies. You can view the history files directory here to look at the available ticker names (SYMBOLS) that you would use as a command line option -sSYMBOLS when starting scfeed.

Example usage: scfeed.exe -scoinbaseUSD,coinbaseEUR,btcexUSD

Coinbase feed is working nicely. Thank you.

Since BTC-e went down, the Litecoin feed is no longer working. Is there a similar history files directory for LTC on other exchanges? I'd like to get the feed working again. TIA.

Thanks DC, I'll give it a try.

Thanks, DC. On another tack, could you add a Coinbase feed to SCFeed?

Anyone notice that the downloads are still working but the live trade is not?

Looks like the live trade socket from bitcoincharts is not returning any data after subscription. A message to tcatm via the forum or a message to the bitcoincharts contact email may alert the site to a malfunction.

Frankly, I'm surprised that it has worked for four years, as the API is not documented or advertised, and is only known from the original sierrachart bridge code (and is likely the only code using the data stream).

DC, different problem now. SCfeed keeps giving a 'URLError = Bad Gateway' error when trying to get MtGox data. Does this for 10 times or so and then closes without continuing on to get data from the other two sites. Any way around this or will it have to be re-configured? Thanks.

6/10/16 - Working again now. Go figure.

DC, asked you about this a while back. Wonder if you could have a look at it. Coinbase has a live feed available at

https://exchange.coinbase.com/trade

and API specs for historical data at

https://docs.exchange.coinbase.com/#get-historic-rates

Would really like to get Coinbase feed integrated into SCFeed now that it seems to be stable. Thanks.

Hello deepceleron.

I'm trying to import okkoin. File size about 9 GB. I receive a memory error.

I cut the file into pieces. Importing successfully, if the file is less than 1 GB.
Maybe there is a way to fix the code in small labor costs?

Thank you.

Thanks for letting me know about this. I'll revisit this code and look at different ways of accessing and importing the files. Are you running 64-bit Python? (the exe here is 32 bit) That alone may fix the issue if it is an error reading or writing beyond 2/4gb. I also had some sorting code that sanitized data that might be using big chunks of memory if it is still in play (haven't dug into this project for a while). If the csv file has 9gb of actual trade data and is not sparse, I would anticipate the sierrachart data files would also grow pretty large too.

Anyone notice that BTCe data is no longer feeding?

It looks like there was a gap in data from Bitcoincharts: http://bitcoincharts.com/markets/btceUSD.html - this likely happened due to changes to the BTCe API that needed a software fix from Bitcoincharts, or actual exchange data downtime.

Sometimes they have recovered missing historical spans of data when bitcoincharts->exchange API connection goes down for a while.

I could remove mtgox as a default, but I'm sure everyone using this has custom configured their own command-line list of exchanges anyway.

i've found cryptowatch.com to be a decent alternative to this for my admittedly simple needs.

Same here. If you close scfeed and restart, it will DL all the data up to current, but no new live feed. Restarted several times during the last two days to keep up.

SCfeed dead again? No updates since midnight.

What exchange are you monitoring? I just ran the post #1 script with no command line options, and it updated 5 days of bitstampUSD and btceUSD history, and is getting live trades from both.

If a particular exchange is not getting data, it may be that the API between bitcoincharts and the exchange is broken (which is why I don't try to write a version that connects directly to individual exchanges - it would need to be constantly updated). You can look at the chart data for btce for example: http://bitcoincharts.com/charts/btceUSD#rg1zig1-minztgSzm1g10zm2g25zv - see that it is up-to-the-minute, and then compare it with the trade data from the exchange you are watching. If the other exchange has no new data, you should notify [email protected] that the feed is down.

Hmmmm..........Just ran it again and all is working fine. Was down for at least two days for me. Thanks for replying.
