SierraChart bridge - Realtime Bitcoin charts [v0.5] (MtGox, Intersango, ...)

[Hunterbunter]

Does this stop working if bitcoincharts have a bad gateway issue?

does anyone know how to create a trading history video with Sierra charts? (other than slowly recreating the chart and video taping it manually)

There's history playback in Sierrachart (Ctrl+R) and you can record it using many tools like FastStone Capture (I have good experience with it, however it costs $20).

its been months since i've used Sierra charts but want to get back into it to do some analysis.

is the OP still current?

 slush, can i save an ongoing daily and weekly Historical chart with labels using your feed with Sierra?  or does it only work with Intraday Charts?

thanks. the history playback window appears but then it is so fast that I can make any use of it - no matter which settings I use..
any idea how to slow down the replay?

Yes, Sierrachart uses Chartbooks ("*.cht" fileformat) for storing labels, drawings etc. It's independent on data source or chart type. And yes, OP is still up to date.

I'm quite surprised that it doesn't work for you. I'll test it on my machine soon...

[slush]

myself: not by an option, but it's pretty easy change in the code directly. Unfortunately Sierrachart cannot handle volume as float, so the only solution is to multiply market's volume by 10**n (currently n=2 for two decimal places) and then move decimal place "in your head".

Everything you need to change for full precision is replace "10**2" by "10**8" in the sierrachartfeed.py source code (it is currently on two places).

Slush, did you check it already?

I checked it right now and it works. Maybe it's not intuitive enough; firstly you must move your chart to the history a little (use left arrow or bottom scrollbar). Then press Ctrl+R, set some reasonable speed (I used "100" on 60min graph to see if it is moving somehow). After pressing "Play", it starts drawing chart from current position to the end...

I just released version 0.5. It now stores all Bitcoin markets by default (it's because default symbol option is wildchar "-s *") and improves connection stability by using TCP keepalive on bitcoinchart's socket.

@slush
software packing and editing is not my best skill ....

So you're probably interested in new option "--volume-precision" introduced in version 0.5 :-). Simply start feed as "sierrachartfeed.exe --volume-precision 4" and you'll have what you requested...

Installed 835 on linux and running good so far.

Once I have a chart open (mtgoxUSD) How do I open in another tab cryptoxUSD?
How do I add Volume bar ask/bid to the bottom of the window?

I only been playing around with this for 30 minutes so be gentle.

It's same as for mtgoxUSD. Just select "New intraday chart" from main menu...

How do I add Volume bar ask/bid to the bottom of the window?

You can add chart analysis in Analysis->Studies window.

Yes I see, 'F6':

I chose 'Volume-colored based on Volume' Add>> <APPLY>
Then I chose Settings (along the right side) > width 3 > <OK> > <APPLY> > <OK>

Cool.

Do I have to start a fresh terminal for each exchange I want to monitor?

Code:

$ wine sierrachartfeed-0.5.exe -s cryptoxUSD

Code:

$ wine sierrachartfeed-0.5.exe -s mtgoxUSD

This didn't work:

Code:

$ wine sierrachartfeed-0.5.exe -s mtgoxUSD cryptoxUSD

[Portnoy]

This didn't work:

Code:

$ wine sierrachartfeed-0.5.exe -s mtgoxUSD cryptoxUSD

This should ( at least it does on windows ):

Code:

$ wine sierrachartfeed-0.5.exe -s mtgoxUSD,cryptoxUSD

No, feed is downloading *all* quotes by default,storing them in separate files (<market>.scid). Default behaviour is that markets are lazy-loaded,that means feed will dowload market history once there's some move. If you specify market in -s parameter, market history will be downloaded actively after startup...

[check_status]

The only (<market>.scid) files available are the ones I specified in the command line above. There are no other .scid files. You are saying other markets should be available to choose, I'm not sure what's wrong?

Are you using latest version, 0.5?

Edit: I see you're using 0.5. Then if you don't specify any market, feed will use "-s mtgoxUSD,*" by default. It means: Download mtgoxUSD history on startup, then start feed and store all other streams as well (and download market history on first update).

If you're using -s parameter without "*", it will stream only markets which you defined.
