Keep in mind that Tradingview charts adjust historical prices to reflect dividend payments, therefore my lines get changed every time a dividend gets paid. Over the long run this is helpful so you can see total (untaxed) return on a chart of any stock, , and compare them. However, it does alter the actual prices that the stock traded on that day.
Lastly, the CIRCLES are the closing price with an average range around it to help the expiration price "stand out" to your eye. The horizontal RED LINE is the close, but it might need adjustment based on dividends that have or that will be paid.
Questions or comments? Please ask or tell.

As for previous expiration prices highlighted on this chart, I believe past expiration prices are important "market memory" levels. Major players are familiar with certain price levels and are ready to act at those levels. I would like to fade out the colors of the OLDER lines and keep the newer expiration levels in more BOLD colors. That would help too.
Welcome to TradingView and I hope you post a few charts and I'll check them out. I have been on here since about Sep'11 and I love it. The charts, saving ideas, posting thoughts, commenting on others' charts, voting "agree" "disagree" is valuable.
