Mail Block: Listener questions and comments
Question from Mukund Ambarge - Hi Team, I had a question on theta decay. I understand that delta is in constant flux with every tick move in stock, the delta/gamma changes. IV is in constant flux with buying and selling of options and volume etc. So Vega changes with option transactions. But theta decay is the only one which is always in a steady pace i.e. it\\u2019s not like it will decay quickly today and slowly tomorrow. The question is, when the theta decay is really adjusted in the prices of options. Do the theta decay get adjusted at every tick move - or every hour? If it is adjusted daily. Then when is the theta decay taken out of options. Early morning before start of trading? Or late in the day like last few minutes that whole days theta is taken out? Also I do not know when is weekend theta taken out of prices? Friday early morning or Friday ending or middle of the day? Basically when does market maker run the prices with the model and set the prices? Only once before trading starts or does he keep adjusting every minute/hour/tick based on demand/supply?
