Re: Opentick Reliability

Hi,

I'm looking for a few opinions on Opentick... On the face of it, it seems like an extremely good product - a free open-source API that provides free historical data and tick-by-tick live datafeeds for a few dollars a month for each exchange. They promote their data integrity and redundant architecture, along with wide platform support.

However, it seems that not many people are talking about it and those that are have problems. Personally, I tried to download historical data for the Dow Jones Industrial Average, and I found several posts on the internet pointing me to different symbols and exchanges some of which seem to have no-data / old partial data.

Can someone please set me straight on it, and if possible point me to historical data for the Dow Jones Industrial Average, and the cash Forex EUR/USD (does Opentick cover this at all?).

If not, I've had a look around at the different feeds but I don't think there's anything else like OpenTick promotes itself to be?

thanks and regards,
omega

There is no FX data provided by OpenTick, but you should be able to get Globex forex futures data.

Do you want to use it for historical or real time data ?

I have been using it to download historical US stock data - about 8000 stocks on a daily basis 1 min and 30 minute bars over the last couple of weeks and it seems quite reliable. I use my own Java application for this.

The current historical stock data seems OK. Historical data prior to about 2005 is pretty ropy and you couldn't really rely in it for anythin much. There are also some quite big gaps in the older data. However the data over the last 12 months seems fine.

I will be having a look at some of the historical index data in the next few days.

I'm also using my own Java code for the real time data - L1 only at the moment. It seems reliable, but sometimes seem to lag IB data a bit, but subscription to different exchanges might be a factor here. I need to give it longer to make a decent assessment of the usefulness of the real time data.

Market scanner. Of course quite a few get skipped over fairly quickly due to lack of volume, bulletin board etc.It's just easier to get the lot and screen out what is not needed. Amongst other things my software calculates sector (or rather industry indices) based off the industry compositions on Yahoo. All this suff is screen scraped so it's automated.

The scanner can rank relative strength of sectors/industries/stocks, filter by just about any technical criteria etc etc and do it for now or any specified time in the past for research purposes. Simplest use - find the strongest/weakest stocks in the strongest/weakest sectors.

I think LurkerLurker uses opentick as a datafeed.

Thanks guys for your replies. I'm glad to hear that the recent historical data seems present and intact. Can you please provide me with the exchange details for the Dow Jones Industrial Average that works, as I have seen a few very different ones about.

thanks,
Robert.
