PEN Price vs Max Options Open Interest

How to read this: the line is the stock price; the bars show where the most option open interest sits each day. Strikes with heavy open interest often act as magnets or barriers for price ("max pain" zones). Scroll right for the most recent days.

PEN Max Change In Options Open Interest

How to read this: each bar is the option contract whose open interest changed the most yesterday. Green bars = new positions being opened (conviction building at that strike); red bars = positions being closed. Call builds above the current price suggest upside bets; put builds below it suggest hedging or downside bets.
