BAP Took a CPS exp 5/17 at 165/160. All week long it's been trading between 170-175 then out of the blue a wick down to 155 last night... no news only positive upgrades all week. Even though the open interest was very low that doesn't explain the CLEAR PRICE MANIPULATION OF THE UNDERLYING BY MARKET MAKERS WHO DON'T WANT TO PAY US TRADERS. THIS IS ILLEGAL BS!!!
