RSI Bamm

The standard RSI only has the definition of upper band and lower band, which means overbought and oversold respectively.

But sometimes, we need the middle band to help complete some analysis, such as RSI BAMM (bat action magnet move).

This indicator adds the definition of the mid-track to the standard RSI and automatically identifies the RSI BAMM. Hope it is useful to you.

标准RSI只有上轨和下轨的定义，分别表示超买和超卖。但有时候，我们需要中轨来辅助完成一些分析，比如RSI BAMM (蝙蝠吸磁运动)
此指标在标准RSI的基础上，加入中轨的定义，并自动识别RSI BAMM。希望对你有用。

The midpoint of BAMM's line drawing is in the center of the 2 arrows, so it looks better and more comfortable than before

BAMM的线条绘制中点在2个箭头的中心，这样看起来比之前的好看和舒服一些
