To calculate Bollinger Bands using F#, you can follow these steps.

Step 1: Define the necessary variables and input parameters.

1 2 3 |
let inputPrices = // list of input prices let period = 20 // period for calculating moving average let numDeviations = 2.0 // number of standard deviations for upper and lower bands |

Step 2: Calculate the moving average of the input prices.

```
1
``` |
let movingAverage = inputPrices |> Seq.windowed period |> Seq.map (Seq.average) |

Step 3: Calculate the standard deviation of the input prices.

```
1
``` |
let standardDeviation = inputPrices |> Seq.windowed period |> Seq.map (Seq.stdev) |

Step 4: Calculate the upper and lower bands using the moving average and standard deviation.

1 2 |
let upperBand = Seq.map2 (+) movingAverage (Seq.map (fun x -> numDeviations * x) standardDeviation) let lowerBand = Seq.map2 (-) movingAverage (Seq.map (fun x -> numDeviations * x) standardDeviation) |

Step 5: Return the Bollinger Bands as a tuple of lists.

```
1
``` |
let bollingerBands = (upperBand |> List.ofSeq, lowerBand |> List.ofSeq) |

You can then use these steps to calculate Bollinger Bands for any given list of input prices. Keep in mind that Bollinger Bands are a technical analysis tool used to determine possible overbought or oversold conditions in financial markets.
