Hi everyone, I'm trying to learn scalping ES,YM,ER2 bid/ask. Trying on my own, so I feel that I'll need some help here. I trade with IB+ZeroLine Trader, set to autochase bid/ask but usually no fill for 10min. so even if i get one side filled the quote will be hell knows where in the next ten minutes and at the end it's hardly scalping. Please......What am I missing......? I would appreciate any suggestions. Thanks.
