Overview
波段交易系统（动态比例减仓版） enters when a fast EMA exceeds a trend EMA by a minimum slope percentage, price pulls back near the fast EMA, and price trades above a 60-period EMA filter. Position scale-out occurs incrementally when price reaches the upper Bollinger Band, governed by a bar-based cooldown timer. Full exit triggers when the fast EMA crosses below the trend EMA with an optional bearish close filter. It plots entries and exits on the price chart and lacks a predefined stop-loss order.
