coveredCall {bullishTrader}

Calculates Profit and Loss (PnL) per share (or unit of the underlying) and Breakeven (BE) point at expiration for Covered Call and draws its graph in the Plots tab.

Description

This strategy is also known as buy-write strategy that results from buying stock and writing a call option with a strike price X against the stock position. The outlook of trader or investor on the stock price is neutral to bullish. The covered call strategy has the same payoff as writing a put option (short/naked put). While maintaining the long stock position, the trader can generate income by periodically selling OTM call options (Kakushadze & Serur, 2018).
