remember to adjust the volume dividing it by 100.

hit F5
go to advanced settings 2
change "volume/open int. multiplier" to 0.01

Good tip, cheers.

You can also create 'custom' studies by overlaying one study on top of another. Set 'scale' for the study to 'Independent'. Example: I added a StochRSI study and used a slow stochastic study (using only the 80% & 20% lines) as an overlay to customize the chart.

If you like my post please feel free to give me some positive rep https://bitcointalk.org/index.php?action=trust;u=18639

bitcoincharts is providing only limited history (I think it is 3 days), so if you're mising data in longer history, don't delete your scid file Wink.

btw sometime i report this error:

This happen when bitcoincharts is down for maintenance. Historical feed then return HTML page instead of CSV with trading data...

Yes, this happen when mtgox's websocket interface close connection for some reason (server restart, ...) and websocket connection fails. This is bug on my side, but I'm using 3rd pardy websocket library and I didn't find a proper way how to reconnect after such failure (better said; I even didn't find a way how to catch this error and not let the script to crash completely :-/).

Short answer - no.

It is using historical feed from bitcoincharts.com (URL to CSV is easily readable from source codes...), but server provides only limited history (+/- 3 days).

But I think that providing historical data would be interesting (paid) service for bitcoincharts.com, because they _have_ (almost) complete trading history in database...

Hi Slush,

The newest change to the websocket feed has your bridge grab the PLN as USD... resulting in some funky charts Wink
any fix coming?

Oh, I see mtgox added other currencies to the realtime feed, which break price charts in Sierra. I'll fix it and release new binary soon (tomorrow?). In the meantime, please use parameter "-w" as workaround (that will skip websocket and download clean data from bitcoincharts).

Thanks for release of new version. I've just noticed data pulled from mtGox is delayed by 15 minutes. Is this to be expected? I'm not very happy about this...

I understand, unfortunately this looks like a problem of data source (mtgox).

Ha-ha!  Grin
bitcoincharts.com is also delays its data for 15 min
I have to do some tweaks in BTC Trader to handle this correctly.

Do you mean BTC Trader does not have delayed data? Do you use different data source then?
