RE: Sell limit order1 May 2019 10:22
Im not sure it would work as the MM's will play games below that price of you limit order unless you place it very close to the current market price which you obviously would not want to do. However if you were to put in a stop loss a market maker can see that number and may drop down to buy your stock at the low price and then resell it for a profit.
Its a rigged market, IMO, but certainly in your interest to understand the rules.
