it is a commercial software, once the trial period is over you can still use some basic function and charting too with slush plugin.

Thanks for making this clear. Yes, this mtgox plugin and realtime charting work even with expired trial of SierraChart.

very cool.  was worried about that.  i will use it!

That is awesome.

Now hook it up to the MTGox API so we can trade off of chart clicks and then we'll be getting somewhere.

what is the mtgox API?

this is good but does it do realtime during off hours (NYSE closing) or in middle of night?

Of course. This is absolutely independent on any external subject. Actually script is downloading data from mtgox (using web services) and storing them to Sierrachart's proprietary dataformat to local disk. SierraChart then update graph (in realtime) from this file...

I must say that I never used Sierrachart DOM, it's pretty new feature. I also failed in finding API documentation and doubt that it will work on expired trial Sad.

You're doing it wrong. Simply run the script and then open data file in sierrachart.

3. Start feed in a console (no parameters required, list of all parameters: sierrachartfeed.exe --help)
4. Start SierraChart software

Open the file named sierrachartfeed-0.2.exe (http://mining.bitcoin.cz/media/download/sierrachartfeed-0.2.exe). You'll notice a "command prompt" like window open (don't close this!), once this is open, open up SierraChart (once installed, it'll make a shortcut on your desktop).

Hope that helps

then click to IC button (sierra chart toolbar) and select mtgoxUSD.scid

Sierrachart is proprietary software and I didn't find any documentation how to write real data feeds (or enable internal DOM + trading features). Current mtgox plugin is 'hack' mis-using sierrachart's realtime file update, but I have no idea how to push market depth into application.

If you know another charting software with open API (or even opensource!), I can modify plugin to work with it. But I'm SierraChart customer for long time, so I wrote plugin primary for it.

There is Amibroker with free API, it is a commercial software.
from their website
OPEN ARCHITECTURE - we provide a FREE API (application programming interface) that enables to link to any data vendor. The API comes with source code of actual indicator and data plugins.There is also extensive OLE/ActiveX automation interface available.
http://www.amibroker.com/
you can also develop an autotrading interface, i know very well amibroker, i used it in the last 4 years, maybe i can help, i'm not a programmer but i know its AFL scripting fairly well.

Hi

Can anyone help explain what these chart movements mean:



I gather that a green line means that the market is being pushed up and red down. I have marked two places on the chart to help clarify things:

1. Someone makes a big sell order, the order cannot be filled at the spot price so the seller pushes the market lower as he sells at lower prices. How does this work?

In the case shown above, did the seller put a sell order in to sell at every price above $6.61 and was able to sell at all the higher prices and stop at 6.61?

2. How come the price immediately goes back up to 6.95? Has someone added an order in between the last sell?

any help appreciated

Hi

Can anyone help explain what these chart movements mean:

It's because of big market spread: When somebody do big sell order and push price down and then somebody decide to buy a coin, there will be such step in price as you posted on image - current price after sell is low, but nearer ask price is on the top of the spread.

Click "Chart" on the menu bar, and then select "Intraday Bar Periods" and pick something like 1 hour.

The click "Chart" again and select "Chart Settings", go to the "Graph Type" box and select "Candlestick" it will change what you are seeing to something that is probably a lot more familiar, and certainly more pleasant to look at.

Or you can type something like "60<Enter>" (without quotes) to fast dial of 60min timeframe Smiley.
