You are right that no one can sub penny front run my order ON the exchange. But they can sub penny front run my order OFF the exchange in dark pools. The end result is the same: I do not get the fill, because I am being sub penny front run.

Thanks

Front running: the practice of a stockbroker executing orders on a security for its own account while taking advantage of advance knowledge of pending orders from its customers. Some brokers let HFTs do the dirty job and split the loot through access fees. To me: same same To the...

Banks/brokers sell access to their dark pools to HFTs - i.e. dark pools are lit for HFTs paying for access. HTFs can then front run using sub penny orders.

I agree that it will change when it becomes an ECN. But as long as it remains a dark pool, HFTs and brokers cannot see my limit order. They have to ping IEX with 100 lot orders to see my limit order. My thought was that as long as IEX operates as a dark pool and I only post small limit...

Interactive Brokers has opened up access to Investors Exchange (IEX) – the exchange described in Michael Lewis’ new book Flash Boys. Can I avoid being front run by sub-penny orders by directing my limit orders to IEX?

Interactive Brokers has a data variable called "After Hour Change %." You can use it for a specified list of tickers or as a column in market scanner. After hours trading starts at 16:00. However, the "After Hour Change %" does not appear until 16:15. Today the data did not appear for NYSE...

I have just read the entire 29 pages. I wish I had been too lazy and just read the two lines above. Put differently: HFT trading outfits enjoy trading advantages. Trading is a zero sum game. If you compete within their game, their gain will be your loss. Hence, find a different game. It...

Thank you for your reply. I was able to trade NFLX last week without any issues. Did you trade in the aftermarket or the premarket?

zdreg: I did not have a position. I wanted to short. I have not experienced the issue trying to close a long position (fortunately).

western: Thank you for your reply. Last week I did indeed experience the issue in the pre-market. I contacted IB and they solved the issue. I was able to trade and no harm was done. This morning, however, I could not trade NTE after the opening - in the regular session. I did manage to...

I tried to short NTE after the opening. However, I received the following message: "Price below limit" IB fixed the issue, but NTE was down 6% more at that point. I have had the same experience with a another stock within less than a week. Have anyone had the same experience? I...

It is extremely naive to believe that your broker is unbiased when filling your orders. My job is to take that into account when trading. I do not believe it is any better with any other broker. Having your opening orders freezed for 26 minutes after the opening is NOT what I asked for...

PRLB is a good reference. 15:32:40 yesterday my PRLB OPG buy order filled at 47.94 whereas the opening price is recorded at 46.70 - slippage 2.7%. This is ok because: 1) I could cancel the order at any time up until the order was filled at 15:32:40 2) I can stop using OPG orders...

I agree it was a BS title. I did and do not expect any help. I wanted to let others know what happened and I needed an outlet for my frustration (wrong decision, wrong venue). And I wanted to spare my hand which has an above average number of bite marks year-to-date.

I did get the correct price on RATE. That is not my complaint. Read my post.

I agree on this. IB from time to time cancels OPG orders. It is safe to assume that the cancelled OPG orders on average are ‘in the money.’ If NYSE OPG orders sit too long, I cancel them myself and fill the orders manually. There is also some slippage on the executed orders. I know...

I have traded for a living for 10 years. I have never seen OPG (opening) orders clear after more than 26 minutes. I did get the correct price on RATE. The problem is the selective cancelling of my OPG orders. My RATE order did not get cancelled, because it was out of the money after...

Thank you for your reply. I will save the log. Below is a more precise description: Order: Short RATE at the open IB execution: short RATE 26.5 minutes after the opening at 10.02 where the price is now 10.30. I tried to cancel the order throughout the 26.5 minutes, but it could not be...

I received a message that NYSE issues R - Y could not trade due to a technical issue at the exchange. Consequently, all my 'market on open' orders at NYSE were cancelled except one. 'RATE' which had moved significantly against me did not cancel as opposed to e.g. 'RKUS,' which had...
