MQL5 Wizard provides the automatic creation of Expert Advisors (see MQL5 Wizard: Creating Expert Advisors without Programming).

It's time consider the trading signals, based on the Alligator technical indicator, presented by B.Williams in "Trading Chaos". The strategy called "Signals based on the Alligator" (when creating EA automatically in MQL5 Wizard).

The system is based on three moving averages (Lips, Teeth and Jaw lines), and oscillators, calculated using the difference between them. The trading signals are generated after crossover of the Alligator lines, depending on trend, determined by order of these lines. In the case of upward trend the Lips line (with minimal period) is the highest, the next is the Teeth line, and the lowest is the Jaw line. The similar but opposite case in the case of downward trend.

• Open long position: crossover of the Alligator lines and increase of the distance between them in the case of the upward trend;
• Close long position: upward crossover of Lips line with the Jaw line;
• Open short position: crossover of the Alligator lines and increase of the distance between them in the case of the downward trend;
• Close short position: downward crossover of Lips line with the Jaw line;
