Topic: SierraChart bridge - Realtime Bitcoin charts [v0.5] (MtGox, Intersango, ...) - page 15. (Read 142194 times)

 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?

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?

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).

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

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

Instructions for "daily, weekly, monthly" chart
Go to "Chart" - "Interday Bar Periods" - "Custom..." and enters the value "DaysToDisplay\Loads" 9999 , "BarPeriod" 1-0-0 for daily, 7-0-0 for weekly, 30-0-0 for monthly


Thank you! 

You're right, delay on historical feed is annoying. I'm "fixing" it by running sierrachart bridge everytime and opening sierrachart only when needed. Bridge itself has very small footprint. But you're right that some solution to re-download missing data would be great. I'll think about it little more.

Hey Slush,

Thanks for creating this! I've using this a lot. I have ran into a few problems with it, though. If I see a big move on Mtgoxlive I usually open sierra chart to provide me accurate realtime data by using this wonderful tool. The problem is that when I open it after a big move, it downloads the historical data, but that data is always lagging behind, so the big move isn't downloaded. Then it opens the streaming socket and receives data from after the big move, which leaves strange gaps between different bars in sierra chart. The same behavior can be observed if my laptop happens to go to sleep while your application is open and then wakes up. There's a lot of missing data. I know your program is open source, but I have zero experience with python, so I'm not sure if I could program it myself, although it should be quite simple. I also don't have any experience with compiling python applications.

Anyway, here's some pseudo code that wouldn't prevent the "bugs" from happening, but it would fix it upon opening the application again at a later time.

If (mtgoxUSD.scid.bak exists){
   copy mtgoxUSD.scid.bak to mtgoxUSD.scid;
}
else{
   create mtgoxUSD.scid;
}
downloadhistoricaldata();
copy mtgoxUSD.scid to mtgoxUSD.scid.bak;
openstreamingsocket();


So basically, it downloads the historical data, backups the file and starts writing whatever that's added by the streamingsocket to the original file. Once you use the program again, it copies the backup over the original, effectively discarding any data that has come through the streamingsocket, and downloads the historical data again until it's up to date. So any data that's missed because the computer/laptop went to sleep while the application was open, or whatever data that's missed due to the historical data lagging will be added upon running the application again. This would prevent a messed up mtgoxUSD.scid which requires a download from the start. Let me know what you think! If you have any pointers on how to get started with Python, I could probably implement this myself.

Thanks for reading, and thank you very much again for this wonderful application of yours!

The general discussion forum may be a better place to ask. 

Hi,
do someone know any news about TradeHill's SEPA account?I'm trying to contact TradeHill's admin but i can't.
Thank you for your attention to this matter.

Message from Sierrachart? You can ignore it, sierrachart bridge runs even on unpaid SC version. Otherwise you're doing something wrong.

Also keep in mind that SierraChart is charting software for stock and commodity markets. 45$ for two months is really wtf - because it's the cheapest professioinal platform with trading data I've ever seen ;-).

im getting a disconnection notice saying i need to pay.  and the prices are absolutely redic!  something like $45 for 2 months wtf!

Looks like a bug in bitcoincharts.com feed... I'll ask there.

Ok, I'm still getting "Exception: Historical download failed: year out of range, use -y to disable history", and disabling history is all kinds of un-useful.

Has anyone come up with a work-around to get the MtGox historical data back?

You obviously didn't followed the instructions correctly, because you need to open *intraday* chart, not daily chart .

I tried to follow the instructions of the first post, but all I get is a black window in Sierra and this log:


Anyone has a clue?
 

You didn't installed Sierrachart to default directory, did you? Please add "-d" option and specify the full path to "data" directory of your sierrachart installation, for example

well i found out that i was originally double clicking it...found out your supposed to run it through the cmd prompt.  all it takes is to type the file name, yes?
i renamed the feed to make it easier it is the .4 version

does sierrachart HAVE to be installed in the root of C:/?

EDIT: seems like it does indeed need to be in the root of C:/  working!

I was thinking about it, but AFAIK Sierrachart's scid file don't provide data structures for storing bids and asks separated. There's only bid/ask volume which isn't enough...

Solution: Don't pick dly. Use only Intraday charts and select .scid files.

About other errors  - you can freely ignore all errors about unknown symbols and data feeds. It's because sierrachartfeed does not use "official" feeds from forex/commodity markets.
