There was no opportunity. Even if there was a small after hr bid, do you think your theoretical offer was first in line ?? As other have said, move on.
I have not traded stocks, ETFs/ETNs in years, but years ago I did trade after-hours earnings, announcements, indictments, etc. It is possible to get filled on your limit orders. Only limit orders are accepted, so it only first come-first served at that price. You anticipate where the price will be, not where it is currently. For example, on 10-15-14: NFLX dropped over $123 at one point on an earnings miss. Some traders specialize in trading those fast, crazy, big moves after hours. Anyway, good luck in your trading.
