Details

According to conceptual details given by Cohen (2015), and a closed-form solution provided by Kakushadze and Serur (2018), this method is developed, and the given examples are created, to compute per share Net Credit (V0Cr) on initiation day for Protective Call and draw its graph in the Plots tab. EXAMPLE, Short HypoMedia stock at $14.00 (inflow) and buy HypoMedia December 15 call at $2.00 (outflow). This is a net credit trade as the net cash inflow equals shorted price realized minus call premium (call price) paid on call purchase.
