Now, our trick is always to ensure deltas of sold options are between 0.25 and 0.35. The delta of 6950 call dropped below 0.25, so we closed that and sold lower at 6900.
Neat isnt' it!
Past few days, I also pondered about cash lying in out trading account and margins used. We had never crossed 50% of the margin, so thought of putting the idle cash to some use. We bought iShares Core £ corporate etfs, so that its value can also be used as a collateral. So now 50% of our idle cash is now invested bond etfs!
