Does anyone here use both option charts AND the underlying stock chart when DAY trading options? I use both as I like to see what's happening with whatever I'm trading. The option chart let's me know what's going on with my money. If I only look at the stock chart I'm missing crucial info. Any comments?
I watch the price of the option/structure i never looked at a chart of the option price as there's almost no information to be gleaned from it. There is no crowd behavior generated by watching the price of the K strike call/put option for delivery in T for example. Better look at the price and IV of the last trades through the day.
I plot historical prices of the positions I'm in via Excel, but I never plot it for single options. That info is pretty much useless (IMO)
