In this indicator I mention some types of indicators such as: MA100, MA 200, Bollingerband, preday- center and midday center.
for MA 100 and MA 200 it is the 100 and 200 moving average
Bollinger band is set with default parameters
The default parameters of Bollinger Bands include a 20-day simple moving average (SMA), an upper band that is the SMA plus 2 standard deviations, and a lower band that is the SMA minus 2 standard deviations.
Bollinger Band Components:
Middle Band:
A simple moving average (SMA) of 20 days, calculated by averaging the closing prices over the last 20 days.
Upper Band:
Calculated by adding 2 standard deviations to the SMA.
Lower Band:
Calculated by subtracting 2 standard deviations from the SMA.
Calculation formula:
Upper Band = SMA20 + (2 x 20-day standard deviation) .
Lower Band = SMA20 - (2 x 20-day standard deviation) .
For the pre-day center line it is the average of the previous day's highest and lowest prices.
for midday center is the average of the highest and lowest prices of today in real time
