Monster Harmonic Trader

Monster Harmonic Trader is a Multi Symbol, Multi Timeframe, Harmonic Pattern Expert Advisor. It recognizes Gartley, Bat, Crab, Butterfly, Cypher, Black Swan, White Swan, Shark and Dragon patterns and trades accordingly. User custom patterns can also be added. Monster supports several entry, reward and risk options.

While the underlying Fibonacci projections and ratios are fairly complex, this expert makes detection and discovery of the harmonics patterns easy. Monster Harmonic Trader gives you the right tool to trade Harmonic Patterns.

User Patterns

Users can add their own patterns to Monster Harmonic Trader. Just modify the Monster_UserPatterns.csv to include your patterns. The .csv file can be found in the files folder of the User Data Directory. A sample pattern is already included in the file.

Free Demo

Monster Harmonic Trader will work in the Strategy Tester. However, only patterns for the selected symbol and selected and lower timeframes are detected. This is a limitation of the Strategy Tester.

Loose Ends

Monster Harmonic Trader is not resource hungry. Every calculation cycle (see the 'Check Pattern Every' parameter) takes approximately one second. The duration of every calculation cycle is reported in the upper left hand corner of the chart.

No support, no profits. What more can one say?

Interesting idea but default settings result in losses at around -5 to -10% after 1+ month testing on several accounts including both live and demo accounts.

Removing all live accounts, will monitor and update if demo accounts gives any positive results in the future.

Let me put it this way... there is a reason why there is no live signal from the author for this EA. If something changes, I'll update my review but until now, i'd recommend to stay away from this EA.

The idea behind is great and I'm sure Paul did his best to creat cutting edge EA. I start running the EA on two accounts - ADSS London and Roboforex procent and I will update the EA performance in two months. I'm giving 5 starts already now, because it's not an easy job to code EA based on harmonic patterns.
