Here is a screenshot of yesterday's order flow in AAPL. I have a specific question regarding "net premium" and I'm also interested in any other things to look out for when interpreting this information. Here is Livevol's definition (and example): Net premium: The overall premium position accumulated by market takers (customers) through options only for trades on the bid or offer; i.e. people buying or selling option premium (vol). So looking at AAPL, the call premium was +10.1M. Does this mean that the market thinks calls are underpriced (vol is low) and as a result people are buying them? Net premium for puts is -$1.4M. Does this mean that the market thinks puts are overpriced, so they are selling them? Net premium says nothing about direction, right (that's what net delta is for)? Thank you for helping me with this.
