$SPY Pinning within the Options Market

As you can see, we are seeing what is called pinning, which is when contracts with highest open interest, with their respective strikes, tend to cause a security to gravitate towards those levels near expiration, with contracts on friday not having to be exercised or assigned until monday at 5:30 PM, I see a lot of volatility coming our way. Nikkei down nearly 4% this morning will definitely create pressure for the US Markets, which is being reflected in the futures market as we speak.
