The script plot the normal top and bottom Bollinger Bands and from them and SMA 20 it finds fibonacci logarithmic levels where price can find temporary support/resistance.
To get the best results need to change the standard deviation to your simbol value, like current for BTC the Standards Deviation is 2.61, current Standard Deviation for ETH is 2.55.. etc.. find the right current standard deviation of your simbol with a search online.
The lines ploted by indicators are:
Main line is a 20 SMA
2 retracement Logarithmic Fibonacci 0.382 levels above and bellow 20 sma
2 retracement Logarithmic Fibonacci 0.618 levels above and bellow 20 sma
Top and Bottom Bollindger bands (ticker than the rest of the lines)
2 expansion Logarithmic Fibonacci 0.382 levels above Top BB and bellow Bottom BB
2 expansion Logarithmic Fibonacci 0.618 levels above Top BB and bellow Bottom BB
2 expansion Logarithmic Fibonacci level 1 above Top BB and bellow Bottom BB
2 expansion Logarithmic Fibonacci 1.618 levels above Top BB and bellow Bottom BB
