Difficulty with buying certain low priced stocks at bid (e.g. CTIC)?

Discussion in 'Order Execution' started by Option Trader, Jun 2, 2009.

  1. That's the total volume traded on all ECN's. If you want a more accurate estimate of how long you will wait, you need to look at the rate of trading at the bid on the ECN you placed your order on at the time you placed your order. Which ECN you choose to place your order makes a difference: if 60% of the volume traded on NASDAQ and 20% traded on ARCA, and you had your order on ARCA, your chances of getting filled were lower than if placed on NASDAQ. If you have access to the NASDAQ bookviewer or the ARCA bookviewer, you should be able to see your order moving up

  2. Where do you get this information from about the breakdown between the exchanges? (Note, it was to Nasdaq.)

  4. I would recommend to hide your bid... maybe a black box program is able to step in front of you (although unlikely if it is consistently a 1 cent spread).

    It's very strange that you won't get filled on a CTIC considering it averages 32 million shares traded.

    I doubt it is an issue with your broker if you have access to most ECNs. BTW when I place a bid or ask, any ECN fills me... I don't have to specify if I don't want, whichever is best price gets automatically filled. I used Lightspeed btw.

  5. my experience on these lower-priced high-volume stocks is that there are a lot of peg bid/offer orders active, so whenever the stock ticks, a fair amount of size already stacks on the ecn's. Manual entry on these invariably often only fills when the prices moves through you. I have had the same problem myself.

    You could try EDGA, sometimes it gets cleared without the prices moving through you, but you miss any rebates.

  6. "71 million shares have traded today. The level 2 shows on a typical best bid/ask only about 100k shares, and there are times in the day it can sit there a long time. Hence, I think there is more to it than what you are saying."

    A fair chunk of volume on that stock may be double-printed darkpool fills. Additionally, reserve orders on the ecn's have made displayed size totals substantially less reliable for very active stocks.

  7. Generally, hidden orders have lower priority than displayed orders. If you hide your order, you can only be filled after all displayed orders at your price level. This is not a good idea for CTIC

  8. 1. What do you mean by double-printed? Are these real trades? 2. I thought displayed orders get filled before reserve or hidden orders (After posting this I just realized giggolo posted the same thing in response to the moderator). If so, it doesn't explain how it seems I'm not getting closer to the front of the line.

    Does anyone know the difference between NASDAQ TRF versus simply NASDAQ?

  10. A clear example of someone who has no idea what he's talking about or doing moderating a trading chatboard.
