TWS looks unstable and unreliable. LIT orders I don't know why it can be set only through Rapid Order Entry (Stocks) I could not find LIT even if I select SMART routing or in the supported market (said in IB website) MKT and MKT PRT Again these orders do not take the ASK immediately but keep flagging "blue" in the status. They didn't execute at all. What's up? Thanks! PS: I haven't opened an account yet. I just use the DEMO account to try out TWS features. I wonder if the real simulated account (PaperTrade) reliable. Can anyone answer me?
