Today when the price of Tata chemical increased, i observed that the price of call option increased only till certain strikes. Strikes higher that that actually lost their value. Could anyone explain why? ( Kindly see the image attached)
Nothing lost here. Those were the trades happened only today first time. Yesterday or before there was nothing.
Showing loss price is meaningless here. You can ignore them.
Look at open interest. Entire qty happened only today.
