The Calendar strategy can be quite profitable if it is managed well. I closed the two week campaign for a gain of Rs. 1,50,000 equal to about 14% of the margin capital deployed. I am feeling a bit jittery because we are close to the monthly expiry and the scope for adjustments is limited.
I will start a fresh campaign for the October series.
