/// This is a range-bound trading strategy that generates trade signals using support and resistance levels defined by moving average Envelopes.

/// The upper Envelope is the specified percentage above the 14-period EMA of the Close price and represents the resistance level.
///
/// Support and resistance margin parameters are included to determine when the Close price enters the support or resistance area.
/// The support margin level is the specified percent above the lower Envelope while the resistance margin level is the specified percent below the upper Envelope.
/// A buy signal is generated when the Close price enters the area between the lower Envelope and support margin level while a sell signal is generated when the Close price enters the area between the upper Envelope and resistance margin level.
///
/// Trading Rules:
///
/// Long Entry: A buy market order is generated when the Close price is at or between the lower Envelope and the support margin level.
/// Long Exit: A sell market order is generated when the Close price is at or between the upper Envelope and the resistance margin level.
///
/// Short Entry: A sell short market order is generated when the Close price is at or between the upper Envelope and the resistance margin level.
/// Short Exit: A buy-to-cover market order is generated when the Close price is at or between the lower Envelope and the support margin level.
