• Bill Williams’ trend indicator using three smoothed moving averages (“Jaw” 13-period, “Teeth” 8-period, “Lips” 5-period SMAs). When the “lips” line crosses above the others, it signals a potential bullish trend, and a cross below signals bearish. The three lines opening wide denotes a strong trend (“eating”), while converging lines signal a range (“sleeping”). In robot strategies, Alligator crossings can trigger entries and its state (open vs closed) can define trending vs ranging conditions. In code, MetaTrader can use a custom Alligator indicator or built-in pattern, and cAlgo offers Indicators.Alligator().
