BankNifty Crude Oil RSI Strategy

The "BankNifty Crude Oil RSI Strategy" is a trading strategy that combines the BankNifty index with the WTI Crude Oil price index using the Relative Strength Index (RSI) as the primary indicator. The strategy aims to generate buy and sell signals based on the RSI of the Crude Oil price index, which might influence the BankNifty index.

Here's how the strategy works step by step:

Data Fetching:

The strategy fetches the daily closing prices of WTI Crude Oil from the provided TradingView link "TVC:USOIL" using the request.security function.
RSI Calculation:

The Relative Strength Index (RSI) is calculated using the closing prices of WTI Crude Oil. The RSI is a momentum oscillator that measures the speed and change of price movements. It oscillates between 0 and 100, indicating overbought conditions when above a specified threshold (overbought level) and oversold conditions when below a specified threshold (oversold level).
Buy and Sell Conditions:

The strategy defines two conditions based on the RSI values:
Buy Signal: When the Crude Oil RSI falls below a specified rsiOversold level (default is 30), the strategy generates a buy signal. This implies that the Crude Oil is in an oversold condition, and there might be a potential buying opportunity in the BankNifty index.
Sell Signal: When the Crude Oil RSI rises above a specified rsiOverbought level (default is 70), the strategy generates a sell signal. This implies that the Crude Oil is in an overbought condition, and there might be a potential selling opportunity in the BankNifty index.
Buy and Sell Signal Visualization:

The strategy uses the plotshape function to plot triangular shapes (upward for buy and downward for sell) below and above the price bars, respectively, to indicate the buy and sell signals on the chart visually.
