We recommend activating the intermediate levels of +2σ and -2σ in the indicator settings.
There is a 95.4% likelihood that the price will be located in the interval between +2σ and -2σ, and a 99.7% likelihood that it will lie between +3σ and -3σ.
We recommend leaving the period of the Inversion Bollinger at the default value of 20. It is acceptable to change the range within 13 to 24. As an alternative, it is possible to use whole numbers of 50, 100, 150, 200, or the number of days in the trading or calendar years, 240 or 365. In doing so, it is necessary to understand that using long periods reduces the sensitivity of the indicator and makes it unsuitable for markets with low volatility.
