Hello, DB and OFA Team
I'm impressed with your OFA/Ninja plugin but before buying it I would like to test OFA/Free with IQ feed data for couple of days. But I can't make it work.
Everytime I try to load a chart with OFA/Free according to your instructions (it doesn't matter if I set "days to load" to 0 to see only realtime or any other number to see the history) I see only the message on the chart - "Downloading historical data 01.01.0001 00:00:00" and that's it - no history, no realtime.
I tried to test it with other datafeeds - CQG and Zen-Fire and it worked with no problem, updating in realtime with no problems.
I checked IQ feed subscription and tested it - I can see DOM, T&S, all the bid/ask information on any other charts but not on the OFA/Free.
Please, help me to resolve this issue. What did I miss and why the problem with IQ feed only? Waitng for suggestions...

1.) The chart displays a minimum 6 tick directional move "Probe" (High-Low>6ticks) and a 3 tick reversal before a new bar is printed. The chart is build up from 1 sec time candles.
2.) Instead of the traditional same-price-level Ask-Bid delta which doesn't makes sense to DB, the colors of the markers were selected by calculating the average of the Diagonal Ask-Bid deltas within the last 20 bars.
- Diagonal Delta = current price AskVol - one price level low BidVol.
- Add up all the abs(Diagonal delta's) for each price level per bar for the last 20 bars, and make an average.
- If the abs(Diagonal deltas)>2xAvg, the color is Purple or Pink depending wether the delta is positive or negative.
- If the abs(Diagonal deltas)>1xAvg, the color goes from dark green/red to green/red.
- If the abs(Diagonal deltas)<1xAvg, the color goes from light green/red to white.
3.) If you see a triangle up, the Diagonal delta was positive, meaning more buying than selling pressure. Reverse for triangle down.
4.) If you see a greenish/purple square, this means the was more selling pressure than buying pressure BUT the price went up anyway, and a lot of traders are trapped.
5.) If you see a reddish/pink square, this means the was more buying pressure than selling pressure BUT the price went down anyway, and a lot of traders are trapped.
BTW, I still can't figure out how that works? You have more trades pushing in one direction than the other, but price goes opposite anyway ???
* DB likes Diagonal Ask/Bid ratio's, but personally I prefer to color by Diagonal Ask-Bid delta values.
6.) In blue is the highest volume Cluster, which is not the same as the highest volume price.
7.) The green and red zones are constructed by extending 3 consecutive volume clusters until they are taken out.
8.) The blue and gold zones are constructed by extending 2 consecutive volume clusters until they are taken out.
It's the first time I saw these zones last weekend, and it seems they display good support and resistance levels.
It's also interesting to see what the reaction is when they get broken.

It needs a bit more programming, but I will use these candles in combination with cumulative delta candles and the method taught by Fulcrumtader.

Feel free to setup a sales consultation through the website. We do not actively market this product to the retail industry anymore as we have been in a due diligence process to sell the IP. That said, if it is a good fit for both of us, we will gladly provide access to it.

I am a fan of eSignal - been a customer for over a decade. If enough users request it we will write to it. Because NinjaTrader 8 should eliminate the need for developers to write hacks around the historical data we are trying to limit the development of additional APIs to this version.
I suggest you start a thread here or on our support forum for users wanting an eSignal connection. If the demand is there, I will do it.
As a side note, we should be releasing a version within eSignal sometime next year.

The data comes directly from the IQfeed API and is not stored in NinaTrader at all. It is compressed and stored in-memory. Technically it will build up over time but the way we work with it in the RAM limits this from being a major system resource issue (assuming you actually have a good dedicated trading PC). The benefit is being able to make changes to the chart on the fly with very little time required to repopulate the chart. However there are limitations in place to dump excessive data from the memory if resources are being overly taxed.

I believe we sorted this out directly already - if not please post it again in the technical support forum on the website. I'm clearly not very good at monitoring this thread so asking for technical support here is probably the slowest way to have anything resolved.

Hi DB...thanks for the considering eSignal connection for OFA.
To all futures.io (formerly BMT) traders
I propose that we use this post as a voting poll to gauge the interest of traders for an eSignal connection for OFA. Just vote "thank you" as an indication of your demand...eric
An interesting project, thanks for sharing. I find it a little too busy for my taste, but then I'm not sure of all that's going on.
Re your question, the usual explanation is that aggressive buyers (eg) met much bigger passive sellers. So the positive delta piles up until they are finally exhausted, and then there's no one significant left to buy. So price drops easily on 'normal' delta. This can obviously happen over several price levels (and throughout the day).
But there is also a lot of hedging going on in futures, and that is non-directional.
How are you defining volume clusters? a specific number of levels or...?
You have here three ratio's in a row higher than 2.0 (or what ever cutoff you set) and it draws a green zone.
At the same time, you also have two ratio's in a row higher than 2.0 and it draws a blue zone on top of the green zone, which turns light green.
You have here three ABS(ratio's) in a row higher than 2.0 and it draws a red zone.
At the same time, you also have two ABS(ratio's) in a row higher than 2.0 and it draws a "gold" zone on top of the red zone, which turns orange.
As far as I can see, there are no special algo's for this kind of cluster analysis.
I give the zones a three bars breading room before I cut them off when they are taken out, so it's easy to see when they are violated or function as support.
The 3 cluster zones get the height of three price levels, the 2 cluster zones get the height of one price level because they happen far more frequently, and they also get cut off if the second next bar cuts through them.
Did some one try to split the volume into cumulative delta bars where the price moved in the expected direction vs cumulative delta bars where the price did not move in the expected direction? Would this be the same as cumulative delta Uptick/DownTick?

This is an AMA thread -- a means to ask questions directly to a specified person. This is not a vendor review thread or a general order flow thread.
Please direct questions to DB Vaello of OrderFlowAnalytics if you are posting in this thread. Otherwise, you should be using a different thread to post reviews of the software/services, or talk about OFA in general.
I haven't stopped by in a while and thought I would catch up with everyone. I don't see any new posts - but if you have questions please do not hesitate to ask. We have a training event coming up later this month and still have weekly free webinars which are recorded can be viewed in our forum or on the YouTube.
Hope the holidays treated you well and the new year is prosperous for all!

I'm looking at reviewing your tools, can you advise me on the best way to demo your full functionality.
Secondly, I'm planning on using a CQG feed for live/hist data, on your website you mention this is supported for back-filling hist data, however based on uptick/downtick. My question is how this differs from using IQFeed as the OFA datasource. Note: As I may add a secondary IQFeed but want to asses the benefits against the cost (e.g., whether CQG will do).
Finally, how do the NT8 changes impact you, are you working with the vendor already, or where does this fit into your plans going forward? This hopefully will cover some of the historical data access issues a lot of people have found in the past for order flow based tools and open your product up to a wider list of users with non standard data setups.
Let me know your thoughts on these questions and if you can assist in getting me setup for a trial.
Thanks,
Sand.

1. We have a free version of OFA for you to mess with. It's not a trial - it's just free. That saves both of us a lot of time and agony.
2. Uptick/Downtick is a generic (and faulted) process. It assumes every uptick exchange occurs at the offer and every downtick occurs at the bid. It's just not the case. Is it the end of the world? Not really. The data is close to accurate. The bottom line, there will be differences in what you see historically. Some people cannot stand the idea of inaccuracies - others are less interested in quantifiable results.
3. All of Ninja's partners are waiting for instructions regarding NT8. Since Ninja is relatively dependent on their developer community to continue adding value to the platform, I would assume they have a strategic roll-out process for us. All discussions I've had with them back this up. We obviously hope that the historical bid/ask/last issue is resolved in NT8 but have yet to see anything more than you have. My assumption is we will be ready. 99.9% of that depends on how the release is handled.

Are they still offering a free or trial version of the software? I keep trying to find the download link but have been unable to.

I am intrigued by OrderFlowAnalytics but I have one question.
From my experience, one of the things that makes the market tough is that the waves (one can call them "dominant cycles") are constantly changing. Two downtrends (or two uptrends) never look the same. They always differ in their momentum, their smoothness, the amplitude of the peaks and valleys etc. While this is obvious, it is precisely this problem that makes indicators so useless. Because no particular period/setting can encompass the countless permutations of the market. Hence I generally prefer to use indicators or techniques that do not rely on an input from the user. If I have to define the period, smoothing, or any other parameter, the indicator is usually of little value for me.
So my question is whether OrderflowAnalytics is in the same boat?
I've watched the presentations you gave and your explanation of the ranking of the momentum (green/red, blue and white). Without probing into the firms propriety algos, I was just curious as to whether this ranking (based on some threshold being met) is just another input like every other indicator which rely on some arbitrary "look back" period in order to draw conclusions.
People use a 200 period SMA for no particular reason (presumably because it is "widely watched"). But the 200 period SMA (like any other number used for the SMA) will work sometimes and not work other times.
I dont know much about orderflow so I was curious as to whether order flow lends itself better to quantification than period-based indicators which measure the behavior of a defined number of candles in the past.
Is it the same for orderflows ranking system? In other words is order-flow unique in the sense that one can more robustly define what is "Normal" and what is "above normal", or is the momentum-of-orderflow just another slippery ether that is impossible to objectively quantify in terms of normal vs abnormal.

DB, are there any plans on making the OFA software compatible with the Sierra Charts platform or are the current plans to keep it just on the Ninja Platform for the foreseeable future?
If the plans are to just stay on the Ninja platform, is it because A) there's no customer interest for it to be on Sierra, B) the cost of maintaining it on SC because up their more frequent updates, or C) the cost to be able to re-code to make it compatible with the SC platform?
If the issue is cost, how large of a project would it be to re-code and would you have any interest in the conversion if that R&D were funded by an outside party? Thanks.
