The meaning of the upper, middle and lower rails in the 1.BOLL index (1) The moving range of the price channel formed by the upper, middle and lower rails in the boll index is uncertain, and the upper and lower limits of the channel change with the fluctuation of the stock price. Under normal circumstances, the stock price should always run in the stock price channel. If the stock price runs out of the stock price channel, it means that the market is in an extreme state.
(2) 2) The upper and lower tracks of the BOLL indicator stock price channel are the highest and lowest prices that show the safe operation of the stock price. Although the upper rail line, the middle rail line and the lower rail line can support the operation of the stock price, only the upper rail line and the middle rail line will exert pressure on the operation of the stock price.
(3) Under normal circumstances, when the stock price runs above the middle track, it shows that the stock price is in a strong state; When the stock price runs below the middle of the bollinger band, it shows that the stock price is in a weak position.

BOLL indicator (1) When the three tracks of the Bollinger Band run upwards at the same time, it shows that the stock price is very strong and will continue to rise in the short term. Investors should resolutely hold shares and wait for rising or buying on dips.
(2) When the three tracks of Bollinger Band run down at the same time, it shows that the weakness of the stock price is very obvious, and the stock price will continue to fall in the short term. Investors should resolutely wait and see or sell on rallies.
(3) When the upper rail of the bollinger band starts to run downwards, the middle rail and the lower rail are still running upwards, indicating that the stock price is in a consolidation state. If the stock price is in a long-term upward trend, it shows that the stock price is a strong consolidation on the way up, and investors can wait and see or buy short-term on dips; If the stock price is in a long-term downward trend, it means that the stock price is falling.
(4) The upper rail of the bollinger Band runs upward, while the possibility that the middle rail and the lower rail run downward at the same time is very small, so no judgment is made here.

This is the way for powerful stocks in the rising channel.
