Source Code:

class StockTradingRobot:

$"""$

Class to implement a Stock Trading Robot that calculates the Relative Strength Index $($RSI$).$

Attributes:

$-$ prices: list

List of historical prices of the stock.

$-$ period: int

The time period to consider for RSI calculation.

$"""$

def $\_\_$init$\_\_($self$,$ prices: list, period: int$)$:

$"""$

Constructor to instantiate the StockTradingRobot class.

Parameters:

$-$ prices: list

List of historical prices of the stock.

$-$ period: int

The time period to consider for RSI calculation.

Raises:

$-$ ValueError:

Throws an error if the length of prices is less than the specified period.

$"""$

if len$($prices$)<$ period:

raise ValueError$("$Length of prices should be at least equal to the specified period."$)$

self.prices $=$ prices

self.period $=$ period

def calculate$\_$rsi$($self$)$:

$"""$

Calculates the Relative Strength Index $($RSI$)$ for the given historical prices.

Returns:

$-$ float:

The computed RSI value.
