I placed a pre-market order this morning for brothers acct to buy 1859 NTEK @ .055, shares sold below during the trading day as low as .0522 and my little order didn't get filled? Yesterday for my son's account I place a pre-market order for 10,000 NTGL @ .004 (It closed previously at .0036). They sold me 100 shares for .40 cents and charged me a $9.99 commission. Still waiting for TDA to respond to my message I sent them. Tomorrow I will call them.
