modifiedCallButterfly {bullishTrader}

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

Description

This is a variation of the long call butterfly strategy and the strikes are no longer equidistant; instead we have X3H minus X2M is less than X2M minus X1L. This results in a sideways strategy with a bullish bias (Kakushadze & Serur, 2018).
