Mega Williams is a trend-following indicator designed for cTrader that uses a triple Exponential Moving Average (EMA) crossover system to generate buy and sell signals. It monitors crossovers between a Fast EMA (default 21) and a Mid EMA (default 50), filtered by a Long EMA (default 100) to confirm alignment with the prevailing market trend. Buy signals occur when the Fast EMA crosses above the Mid EMA while price is above the Long EMA, indicating bullish momentum. Conversely, sell signals trigger when the Fast EMA crosses below the Mid EMA with price below the Long EMA, indicating bearish momentum.

Key features include on-chart buy and sell signal arrows, an optional bar-close confirmation to reduce false signals, a minimal dashboard showing current trend direction, and customizable sound alerts with duplicate prevention. Users can adjust EMA periods, signal colors, and arrow offsets to fit their trading style. The indicator is suitable for liquid instruments on M15, H1, H4, and Daily timeframes, with higher timeframes providing fewer but more reliable signals.
