In the observation and reference of BBI technical indicators, when the stock or disk price is above the BBI indicator line, it means that the technical indicators are in a bullish market. When the stock or disk price is lower than the BBI indicator line, it means that the technical indicators are in a short market.
In BBI technical indicators, if the stock or disk price effectively crosses the line of BBI technical indicators, it belongs to the multi-position buying signal of technical indicators and represents the "golden cross" signal of BII technical indicators. If the stock or disk price effectively falls below the BBI technical indicator line, it is a short-selling signal of technical indicators, indicating the "dead fork" signal of BII technical indicators.
Generally speaking, BBI technical index is a kind of moving average long and short technical index, which has strong variability in application. But there is no perfect investment theory and technical indicators in the market, and there will be some misleading information. I don't think technical graphics are almost blind transactions, but also need to be combined with other indicators, market environment and individual stocks for reference.
