last friday when aapl stock price above 350, the 355, and 360 OI did not increase, if traders a very bullish about aapl, then they would close the 350 position and open up the 355, and 360 strike, therefor the 355, 360 OI will increase significantly. That is call
strike roll-up.
But tomorrow, aapl would have a better chance, because the weekly option have been close fast today.
