I use version 589. So you should download new prerelease version.
I also updated my chartbook, because not shure if it was saved.

Is 589 not still in Beta ? SC calls beta, pre-release, I want to believe.

Thanks Chris & Lolu for the re-directs. I'm in same boat as Chris in deciding on an optimal Sierra layout (hopefully that will replicate my previous office platform) and it's a bit of a pain, esp. as on Sierra forum there's little consistancy on terminology ('cumulative bid-ask' means the net of a period's Ask-Bid Volume -- what I had heretofore called 'Delta' -- and at other times means the day's running total of this number). Anyway, here's another possible layout I'm trying to implement (if you like numbers) as it saves screen space. Let me know if you have any ideas. I'll ask Admin, but probably will have to use Workbook. Cheers. Oh yeah, Chris in your screenshot -- I think it was post 5 -- are the white bars meant to track the range of the period's AskVol-BidVol? They look symmetrical. Thanks.

Just curious.....what feed are you all using with your SC charting for BID/ASK differential work?


TIA!

I always use the latest version, and except one time, when they had overwritten the sierra.cfg file, I never had problems.

The white lines are ask/bid volume overlayed by delta with the "BidVolume vs. AskVolume" study. They are not symmetrical, it just might look like, but as you know the delta compared to the ask/bid volume is small, so it is a matter of scale.

For the time being I have to use TA feed, which after comparing to MD at the EL blog, is pretty close, but it seems to me, the demo feed is aggregated. But I hope that I can use the TT feed in the near future, SC promised to implement it hopefully in April.

chris,

I'm on a LIVE account with TransAct, so I'll want to stick to version 580 until SC pronounces 589 stable.

Does version 589 have a process of saving chartbooks to version 580 (or lower) format ? If Yes, could you do this to the 6e.cht and re-post it.

See post #1 of My Trading Diary.

TransAct has three modes of accounts, viz, Demo Mode, Simulated Live, and Live Mode. The Simulated Live and Live Mode have the same data-feed server(s). I have a Live account and was also setup for the Simulated Live account (for SIM-trading) both on only one account. The Demo Mode may have a different data-feed server(s). All the servers could be in the same Data Center, but the server(s) for the Live modes would be given a higher priority in service delivery.

You can add another instance of SC by creating a copy of the SC folder, then you update, and start SC from there. So you can test the new version independent from your live version. Check on the SC support board.

OK.....just wanted to let you know that Transact feed is unusable for proper BID/ASK differential work of any kind. The ONLY feed I am using at this time for all my BID/ASK differential work is DTN.IQ feed. I have tracked and used Cumulative Delta now for over 7 years and at this time all the various broker supplied feeds are all showing data losses (as compared to DTN.IQ feed which has been verified against a high end professional feed). The following feeds are all showing consistent data loss problems for BID/ASK differential uses;

OEC
Transact
Zenfire/Rithmic
TT Fix Adapter (can work, but only with very robust hardware/software)
IB (complete junk "snapshot" data)
Tradestation (timestamps are a mess, etc, etc, etc....LOL!)

I don't even use Esignal either.....have no clue why they even at times can't match DTN.IQ feed daily runs of BID/ASK data. CQG feeds is usable so that is also an option.

DTN.IQ put a lot of money into their data feed infrastructure last year ahead of the CME data output increases on October 5th, 2009. The CME data feed "per unit of time increase" changes really caused a lot of problems for all these various feeds that I have mentioned with problems. Fortunately for those dependent on clean BID/ASK differential data, DTN.IQ is working out exceptionally well as I continue to watch it like a hawk.

Hi FulcrumTrader........I was wondering if you can elaborate what sort of data discrepancy you found when comparing different data feeds to DTN.IQ........are we talking black and white or shades of gray.........
