Recently, I am having problem scalping Forex at IB. ie. Trades are not being confirmed right away; slow data (bid/offer) updated; data interrupt for long time > 10 minutes (I had to unlogged and logged back in while having an open trade !) I have 2 simutaneous different internet connection sources. I have 3 different trading computers and I have been trading with Ib for almost a year. But scalping forex is my new trading style and I can make money most of the time but recent problems above make me wonder is there any chances that the market maker is aware of my scalping style - does not like it - and flagged my Ip to discourage me from scalping. ( I once noted that my trading machine data is suddenly freezed after a few "front-running" bids - placing bid just slightly higher than MM) when the market is dropping to a near major support. Also, one time I noticed that my offer, being offered lower than MM but been masked by a higher MM's offer. My offer did not appear way until later in time after the forex market had shot up and came way down; way below my intial offer price ! I then had to get out at a loss of 15 pip below my initial offer. I am expecting an honest and fair play at Ib but these problems happens just about the same time as I am switching my trading style. I hope this is just a coincidence. Does anyone have similar problems as described above ?
