EMA Envelope and deviation

48
EMA Envelope with Deviation is a trend-following indicator that plots an Exponential Moving Average (EMA) with dynamic upper and lower bands based on a user-defined deviation. The bands can be calculated either as a fixed percentage distance from the EMA or using statistical standard deviation, allowing traders to visualize volatility and potential overbought or oversold zones. It is commonly used to identify breakout strength, pullback entries, and mean-reversion opportunities. The indicator is fully customizable, supports different price sources, and can optionally display crossover signals when price interacts with the envelope boundaries.
