Harmonic Patterns

The EA is developed for Harmonic Patterns trading. It does not use any indicators or high risk strategies like Martingale of order grid in trading. Every deal has stop loss and take profit. Open positions are attended by breakeven and trailing stop function. There is an additional function which checks stop loss level. If an order does not have stop loss or breakeven for some reason, the EA automatically places these levels with a new tick depending on input parameters.

I intentionally did not prescribed rigorous conditions for Pattern determining, so you can flexibly adjust it for a certain way of determining Harmonic Patterns. When the ShowPatterns function is enabled, the EA draws discovered Harmonic Patterns on the chart. All settings for determining Patterns recognition and selection criteria are included into inputs and allow a trader to easily manipulate them.

The EA can be set for recognition following patterns:

• Gartley Butterfly
• Gartley Butterfly. Irregular ratios
• Pesavento Butterfly. (Perfect butterfly model)
• Harmonic Patterns as "nests"
• Harmonic Patterns. Bat
• Harmonic Patterns. Crab
• Harmonic Patterns. Deep crab
