MIT MACD • Filled/Hollow Momentum Histogram

The MIT MACD • Filled/Hollow Momentum Histogram is an enhanced version of the classic MACD.
- Dual-style histogram (filled for acceleration, hollow for deceleration).
- Customizable colors for bars, MACD/Signal lines, and background.
- Background highlight when the slow line crosses the zero-line.
- Fully adjustable parameters, keeping TradingView defaults.

此脚本是经典 MACD 的进阶版，支持实心/空心动能柱体，零轴背景高亮，参数与配色可自由调整，更直观捕捉趋势与动能变化。
