Let me chime in here. eSignal data is great. You can subscribe to Data Manager Only (no charting) at a lower price but need to switch an entitlement on for MD footprint and CVD:

Overview: The MarketDelta Footprint requires not just last price data, but also the quotes at the time of the trade. This information is usually send with real time data but NOT with historical data backfilling requests. This is something that is more recent and many data vendors are beginning to do because of the surge in data over the past few years as a result of electronic trading proliferation.

Resolution: In order to resolve this, there is a required free enablement that you must activate with eSignal by calling them at 1.510.264.1700 and choose option #1. Once it is enabled it will be in the online account maintenance for you to disable later if you choose. This is a FREE enablement at this time.

The name of the entitlement is Tick Server Trades and Quotes TSTQ

Are you saying that the GomCD(NT) + ZenFire feed offers a *NOT* reliable image of the Cumulative Delta action (with a wrong bid/ask classification)?
So that Only Investor RT Pro + DTN.IQFeed can offer a reliable Cumulative Delta analysis?


Thanks

I thought that E-Signal was a great datafeed. At 18-ago-2009, I received a print with volume zero from e-signal for eurostoxx (FESX-09-09) and my indicator crashed.
From that day I only use Zen-Fire.


About OFA, I think that can be programmed in NinjaTrader easily. It is very similar to the action bar of fin-alg.com.
The unique problem is know when a new bar is added.

I have been watching theirs videos and looks like if a new bar is added when the maximum volume cell is exceeded.
If anybody want collaborate we can program this tool for academic purposes (non-commercial, of course). Only need know the reason to add a new bar.

Just to clarify.......NinjaTrader w/Zenfire is good for CD work.

Esignal is NOT always good for CD work (why I have no idea) as I have been seeing way to many with CD plots running off Esignal data in the past months with problems on occasion. The best feeds I have found at this time for proper CD work are the following;

DTN.IQ (I use this feed myself with Inv RT Pro charting)
Zenfire (I use this set up for my Ninjatrader platforms)
TT regular feed (NOT TT Fix adapter feed....that one has issues that TT is working on)
CQG

Other feeds that I have NOT yet been able to verify work properly are the following for CD work;

Transact
OEC
Esignal
TT Fix Adapter
IB (total junk data even with DTN.IQ backfill....will NOT work for CD plotting)
tradestation

Hope this helps!

The new bars "flip" at statistically significant order flow transitions.....what the OFA group has built up makes a lot of sense to me and I give them credit for another way to see the order flow as it shifts.

FulcrumTrader, from what I' ve understood ,you are talking (about OFA methodologies goodness) for the *short* timeframe setups(the "when"), while the "inventory grab" method shows the direction for longer time_frame setup (the "where").
Can you confirm?

Thanks

data visualization is a well studied field of thought, you just have to step outside the bounds of retail trader garbage to find it. Just search for "data visualization" on amazon and you will find more books than you care to buy. For discretionary traders that field of thought should go hand in hand with the field of:
Exploratory data analysis - Wikipedia, the free encyclopedia
Those two combined are basically the well explored science of what you are trying to do as a discretionary trader...The weak link in the chain though is software wise and trying to impliment unconventional data visualization ideas.
While I welcome any unconventional market data visualization software...the entire concept of volume "delta" is extremely flawed as far as real time market mechanics..
While I think the market delta software set to plot "delta bars" is better than anything else commercially available, its still absurdly far from optimal because its knowingly sacrificing the most precious information for ease of implementation.
It doesn't take a genius to figure out that size at the bid - size at the ask, completely cuts off any information as far as the relationship between the two distribution wise.

Yes you are correct......I like what OFA has built for tracking the "when" moment as I call it for the specific trade entry decision point. The "where" to get into a trade would be like tracking price back to a zone of resting inventory while looking for a Delta Divergence, Hidden Divergence, Inventory Grab, etc.
