Each trader has to go for his believes and assumptions as even you do. If those assumptions are wrong, then more skills have to be learned to avoid other wrong decissions. As now all those puts will expire, if now with profit or loss, an other lesson in real market with real money is learned. Some will have sleepless night like we all had in the past when making wrong assuptions and in profit traders will even have more confidence by what is done. Even you or me or others can be wrong with assumptions, as even proved in the past by you and me and others.
I think it is not our problem if others lose or win as long as we stay in the game and go our ways by our assumptions. Or do you think that your question has changed any behavior of any of traders who still want there assumption to be wright, as others could be wrong. Thats how the market is and even successfull traders had to go through hard and loosing trades and this is what have made them strong to stand wrong decissions and take the next trade. Do not knwo what to say more in a neutral way.
