The Tick size pilot program started May 16, 2015. All the comments are from real investors and we all hate the program. On my stock CHKR @ $1.65 the spread is 3% so to buy and sell I have to pay the market makers 6%. Do you think that this is fair and just? It is time to end this program. We investors pay a lot of taxes and you are biting the hand that feeds you. Please do the right thing and get rid of this program that takes money out of my pocket and puts into the pocket of the market makers.
