Open ECry Data Feed

Recommended Posts

Guest Tresor

Hello Brownsfan019 and other happy customers of OEC :),

 

I subscribed today for OEC. I connected OEC data feed to my MultiCharts.

 

1. I first compared data for ES between OEC and Transact and it appears OEC is more accurate than Transact (ES volume by OEC for is closer to the official ES daily volume than ES volume by Transact). This is a good news for me as I am looking for a broker that supplies reliable volume data. The only problem I have with ES is that on 9th April 2009 it did not show the last 1 minute bar. Can someone please have a look at screenshot ''ES Transact vs OEC'' and check if his / her OEC chart also lacks last 1 minute bar for that day?

 

2. Please also have a look at screenshot ''OEC FESX''. FESX is Europe's most traded future contract. The official volume of FESXM9 on 9th April 2009 was 1,056,661 contracts. Here you can chceck the details on Eurex http://www.eurexchange.com/market/statistics/market_statistics/online.html?group=IDX&busdate=20090409&symbol=FESX

 

The catch is OEC data feed reports volume of 3,040,319 contracts for that day. OEC added 1,983,658 contracts during one day :confused: Can you guys check it if your OEC data feed also gives such bad data?

 

Thanks

There seems to be a huge difference in volume readings between the data feeds. The Zenfire hourly volume readings for June ESTX50 futures for 9Apr09 is:

 

31634

92958

53213

45217

44452

25823

192561

142542

103964

134185

35400

15041

17087

17183

318

 

951578 = Total

 

Obviously, we are not all looking at the same movie. I believe it has to do how the data is sampled and transmitted, whether its raw data or whether "something" is done to it to make it more "friendly" to the data suppliers transmission requirements. Those of us who find volume important have a lot of extra due dilligence to do. At the moment, the consensus of people I speak to say esignal or CQG has the truest volume. So those who are trying to use their brokers' feed for charting/analysis have a lot of work to do before deciding on following that course.

This always puzzles me. There is really no excuse for 'missing' volume, all the providers get get the same feed. from the exchange. Actually this is not strictly true I believe there is a separate 'broker' feed and 'data provide'r feed, or used to be at least.

 

If things get overloaded there are two acceptable solutions and one unacceptable one (that I can think of).

 

1) Just keep sending despite things backing up. This will cause 'lag' but all data will arrive intact. I'm pretty sure this is how Esignal does it. I don't use Esignal and have not for quite a while, In the old days before multi megabit broadband Esignal would noticeably lag the actual market if things where fast.

 

2) Aggregate data. IB does this and I think this is an acceptable compromise. If the market is fast they will send all the volume information but may aggregate ticks at the same price.

 

3) Discard data. This is the unacceptable option (imho). The discarding could be intentional or un-intentional (due to 'overloading').

 

I really can't imagine that a mature product would still be bugged to the extent that it lost data in fast markets, it is much more likely to be a 'lesser of two evils' design decision. An email from the provider would clarify how they deal with fast markets and saturated links to clients.

 

It's perplexing.

Hello Momentom,

 

Thanks for posting about Zenfire. Zenfire is wrong by only as little as 105,083 contracts. Open ECry is wrong by as many as 1,983,658.

 

I would love to choose Zenfire, but this data feed does not have a backfill for other programmes than Ninja.

 

For a while I thought this might have been be a problem with Multicharts, but then I created FESX chart with OEC Trader and it turned out again that OEC volume is wrong.

I'm using MC for my testing and Ninja for my trading. I can export data out of Ninja and test it against ideas in multicharts. I'm a discretionary daytrader so this works fine for me. also mc is easy to use for strategy creation - something i haven't mastered in C# ninja speak. You can also get delayed data at a reduced cost from esignal and use that for your testing if you cover a lot of markets.

I have emailed OEC asking them to take a look at this thread to see what's going on. Will let you know when I hear something.

 

Hi Brownsfan019,

 

Thanks for your help. I already e-mailed them with a suggestion of what might be causing this. Please look there is a difference between total volume in Quotes and total volume on charts.

My understanding is that pretty much anything on this list is available: http://www.openecry.com/software/available.cfm

 

Now, you might need to have something turned on in order to place trades there. Since the DAX is on the Eurex, you might not have the Eurex feed on or the account setup to trade there (commissions, margins, etc.).

 

I'd drop an email or go into chat to see if you think you'd like to trade the Dax or Stoxx.

BTW, what are your all-inclusive RT fees at OEC? You can PM me about this.

 

A few months ago someone wrote on elitetrader.com that OEC charged an additional fee for clients who are not US citizens. Do they still have higher rates for foreigners or it was a joke?

Email from OEC regarding the issue:

 

I have downloaded and read 10Mb EUREX API doc and found that they actually send the total qty for a given price instead of just last traded qty. We verified this with Eurex and this is the way they decimate their market data. So the tick data added up will NOT match the total volume. It seems EUREX is the only one who does it like this, at least that we have encountered.

 

Please note: For all exchanges we use tick volumes to create all types of bars: minute, hour, even volume bars. An incorrect volume of individual ticks makes our data incorrect.

 

We have added a workaround for these Eurex contracts that display volume bars incorrectly. This is in the Q&A now and will be rolled out very soon.

 

Sorry for the confusion and thank you for bringing this to my attention.

    • Date: 31st March 2025.   Trump Confirms Tariffs on All Countries, Sending Stocks Lower.   The NASDAQ continues to trade lower due to the US confirming the latest tariffs will be on all countries. In addition to this, bearish volatility also is largely due to the higher inflation data from Friday. The NASDAQ declines to its lowest price since September 11th 2024. Core PCE Price Index - Inflation Increases Again! The PCE Price Index read 2.5% aligning with expert forecasts not triggering any alarm bells. However, the Core PCE Price Index rose from 0.3% to 0.4% MoM and from 2.7% to 2.8% YoY, signalling growing inflationary pressure. This increases the likelihood that the Federal Reserve will maintain elevated interest rates for an extended period. The NASDAQ fell 2.60% due to the higher inflation reading which is known to pressure the stock market due to pressure on consumer demand and a more hawkish Federal Reserve. Boston Fed President Susan Collins recently commented that tariffs could drive up inflation, though the long-term impact remains uncertain. She told journalists that a short-term spike is the most probable outcome but believes the current pause in monetary policy adjustments is appropriate given the prevailing uncertainties. Although, certain investment banks such as JP Morgan actually believe the Federal Reserve will be forced into cutting rates. This is due to expectations that the economy will struggle under the new trade policy. For example, JP Morgan expects the Federal Reserve to delay rate cuts but will quickly cut towards the end of 2025. Market Risk Appetite Takes a Hit! A big factor for the day is the drop in the risk appetite of investors. This can be seen from the VIX which is up almost 6%, Gold which is trading 1.30% higher and the Japanese Yen which is the day’s best performing currency. Most safe haven assets, bar the US Dollar, increase in value. It is also worth noting that all indices are decreasing in value during this morning's Asian session with the Nikkei225 and NASDAQ witnessing the strongest decline. Previously the stock market rose in value as investors heard rumours that tariffs would only be on certain countries. This bullish swing occurred between March 14th and 25th. Over the weekend, President Donald Trump indicated that the upcoming tariffs would apply to all countries, not just those with the largest trade imbalances with the US. NASDAQ - Technical Analysis In terms of technical analysis, the NASDAQ continues to obtain indications that sellers control the price action. The price opens on a bearish price gap measuring 0.30% and trades below all Moving Averages on all timeframes. The NASDAQ also trades below the VWAP and almost 100% of the most influential components (stocks) are declining in value.     The next significant support level is at $18,313, and the resistance level stands at $20,367.95. Key Takeaway Points: NASDAQ falls to its lowest since September 2024 as the US confirms tariffs on all countries, adding to inflation concerns. Core PCE inflation rises to 0.4% MoM and 2.8% YoY, increasing the likelihood of prolonged high interest rates. Investor risk appetite drops as VIX jumps 6%, gold gains 1.3%, and safe-haven assets outperform. NASDAQ shows strong bearish momentum, trading below key technical levels with support at $18,313 and resistance at $20,367.95. Always trade with strict risk management.
