Instead of looking at the chart for every single stock and trying to identity the chart patterns, I am looking for programmatic library that can automatically do this for me. Does anyone know of any such library?

There are a number of stock filtering applications online but none of them filter on stock patterns, only on fundamentals. Even tradestation, which has a stock filtering capability requires you to have significant knowledge of its language and indicators to be able to create meaningful filters.

With that said, why trade stocks which has over 10,000 different ones, a maximum of 4:1 leverage when you can just trade the 4 major currency pairs and watch the economic indicators? You can get up to 100:1 leverage as well so the opportunity to make sustainable income is much greater.

Last, there is no substitute for hard work in making yourself an expert in whatever field you choose.

I have traveled before in this path so thought of giving some options that I have come across. I am not sure which platform you have or if you are already aware of the options listed below.

1) think or swim : You can actually sign up for a demo account to download the desktop and check it out. Has an option called 'Prophet' in which you can search for one or many patterns for a given List. For a matching stock, it will show you all the applicable patterns. I have not used it that much, pattern recognition is not that great but as i said none of them are perfect. Available chart patterns :Triangles, Wedges, Pennant, Flags, H&S, Channels etc . There are also different candle stick patterns available.
I use tradestation as brokerage. But I have a ToS account because i like there option platform and also you can listen to free pit noise (tradersaudio).

2) RampRT:
Real Time Chart Pattern Recognition Alerts
Chart Pattern Recognition Forex and Stock Screener Finds Chart Patterns Fast

There are two versions , EOD and Realtime. Realtime is subscription based + needs dat package, where as EOD is one time $99. EOD does not need any data subscription since it takes data from Yahoo or Google. in EOD version you can also run pattern reecho on Weekly charts. You can run search for only one pattern at a time on the list but for the matching stocks, you can save the list and run the next pattern search only on that list. I like this one a lot because it has something called 'Bob charts' which basically shows the channels, trendiness for all the symbols. Chart Patterns: Support Line Touch,Support Line Break,Resistance Line Touch,Resistance Line Break,Fully Automatic Trend Lines,Fibonacci Retracements (any level).Fibonacci Extensions (any level),Linear Regression Channels,Head and Shoulders,Cup and Handles,Confirmed W Bottoms,Early Double Bottoms,Confirmed M Tops,Early Double Tops.

You can check out the videos on website, also there is a Trial version which doesn't require any CC info

3) If you are more of a FIb pattern guy, you can check out Scott Carneys website for his software. Its pretty neat in identifying different harmonic patterns ( AB=CD , Bat , Butterfly, Crab & Gartley , etc )

Welcome to Harmonic Trader

4) If you are interested only in ABC pattern and have tradestation, take a look at the Radar screen ABC pattern reecho from Suri. His Website:

suriNotes.com, suriNotes, Stock Research, Futures Trading, Emini Trading, Tradestation, Indicators.

This is the best you can get for ABC and it is very robust. You can refer to the website for more details

5) If you interested in Candlestick patterns , check out Stockfetcher.com

P.S: I am not recommending any of the above. I am not affiliated with any of the above nor get any commission (I wish I did ). I have TOS, RampRt EOD version, Suris ABC. I had trial version of HarmonicAnalyzer that I did not extend and tried stockfetcher for a while.

Yes, forgot about http://www.thepatternsite.com/patternz.html.

Advantage is that the software is for free. You need to pay ~ 15 0r 20 per year for data. Disadvantage is that it wont run on Win 7. So if you have all Win 7 machines, then you need to somehow install a different OS (using dual boot or using virtual box etc).

If running Windows 7 the compatibility mode usually permits older programs to work.

"usually" - unfortunately not in this case. That's windows for you.

Guys, thanks for the info. finviz.com also has some filters based on chart pattern. What I am looking for is something little different. I do not want software, but rather a programming library (in any language such as C++/Java/Perl).
I would use this library to set up an automatic trading strategy. I already have some automated strategies running at http://www.strategyard.com/, but so far all my strategies are based on technical indicators (SMA, RSI etc) as they are easy to calculate. But I still have to figure out a way to include chart patterns (wedge, head & shoulder etc) into my strategy.
