L1 Dynamic Multilayer Bollinger Bands (L1 DMBB) are an advanced technical analysis tool designed for the volatility of financial markets. They are based on the traditional Bollinger Bands, which consist of an upper and lower band formed by a multiple of the standard deviation from a simple moving average (SMA), but L1 DMBB provides a richer perspective on market volatility by adding additional layers such as up2 and low2. These layers are located at 2.56 standard deviations above and below the middle line, offering traders a more comprehensive insight into the market.
