I am now believing that..I had a sell order in on etrade for .26 on a penny stock that was entered earlier in day..then I see the shares a being bought for .265..... .269 .27 .27 .275 and on..I was convinced my sell went through...but 20 mins later I see my order was never executed..so peeps were buying shares higher when I was willin to sell lower..I don't get it..so lost alot of profit there...hate etrade now
