Harmonic Patterns are trend reversal patterns especially for the traders who want to master mean reversion aka trend reversal trade setups. Harmonic Patterns are based on the fibonacci extensions, retracement levels, and geometric structures.

Harmonic Pattern-Amibroker AFL Code
/* HARMONIC PATTERN DETECTION
Automatic Detection of Harmonic Patterns - Gartley, Bat, Butterfly and Crab.
Zig Zag is not used in this AFL. It is based on fractals
Contact - [email protected]
Modernized by E.M.Pottasch (Dec 2016).
- All calculations by the original author left as they were.
- Improved visualisation of the patterns.
- Adjusted names of variables, constants and arrays, adapted
using code from David Keleher.
The code I used is the original code from:

CAN ANY BODY CLEAR SOME OF MY DOUBTS
1)WHEN I RUN ANY EXPLORER IT CONSIDERS DAILY CHART ONLY NOT HOURLY OR OTHER
2)WHEN RUN FOR HARMONIC PATTERN IT DOES NOT PLOT THE PATTERN
thank a lot..it is very very good.
where can i have the harmonic patterns afl code ?
Hi Rajandran Sir,
This looks very interesting!!
Can you pls elaborate how to use, how to take buy/sell signals. Also, fractal points are real- time data based or it looks for future data. I mean is it repainting code used to generate fractal points.
Howcan we have the pattern name displayed on chart when the pattern is formed. currently by using this afl, we have to click the last leg point to see which pattern it is and once we click at some other place then the pattern name will not be visible. How to show the pattern name on the chart when it is formed. Any thoughts? Thanks
Hi Rajendran, Did you get a chance to look at my comment posted on December 2, 2014 at 7:06 pm. Requesting you to respond to that with the solution. It would be really great if you could do so. Thank you
Regards

I am regular follower of your site especially Amibroker AFLs. I can say your blog is one of the best Technical analysis blogs in world which i have ever seen, Thanks a lot for sharing such educational and highly skillful ideas with us. Here I have request on Harmonic patteren AFL..
Could you include other Harmonic pattered like 3 drives pattern and 5-0 patteren in you exisiting harmonic patteren AFL. and publish also most of the times this AFL is not displaying what is the pattern and Entry, SL and Exit. and add exploration scanner which we can scan it.Could you tweak this AFL with this points and republish it. You can find information about above patterns in below link.
Once again thank a lot in advance keep you post such education and foreknowledge blogs.

Sir,
Do you have this strategy for MT4? if yes kindly share sir.
I have studied Harmonic Patterns carefully. There are serious drawbacks in these patterns. You can also study them using Bar Replay in Amibroker. You will also come to know that most of the patterns are faulty.
