    FYI: NinjaTrader Beta delayed until Sep/09

    In my opinion they have made the correct decision. The current v6.5 is somewhat crippled by poor software architecture and they have made a sensible decision in delaying the release. There is absolutely no point them rush releasing another version which is riddled with all new bugs...

    MARKET vs. LIMIT Order - Any Difference?

    Unless of course the market is really shifting and leaves your limit order merrily sitting in the book. Could be an expensive choice if the market is moving against your position. As I said, IMHO there are no absolute rules. Best results are obtained by tailoring your execution strategy to the...

    MARKET vs. LIMIT Order - Any Difference?

    I have to say that some of the opinions expressed on this thread come across as somewhat short sighted. All order types have their legitimate uses otherwise they wouldn't exist. Which order type to use depends entirely on the execution you want. They all have pros and cons. It's your job to...

    Adaptive Moving Averages

    Well, without going into a load of unnecessary detail, I'm going to feed the MA a stream of T&S data (so effectively the equivalent of a 1 tick chart). I can configure the sensitivity of the KAMA and VIDYA easily using the period and volatility settings. However, the MAMA is a tricky little...

    Adaptive Moving Averages

    I would never touch a MA based trading system in my life. I just want to use the MA as a trigger to indicate when the direction of price movement has changed in a meaningful way (hence the need for an adaptive MA which can filter noise). Don't worry. The MA is a tiny part of my strategy and...

    Adaptive Moving Averages

    Thanks for the help. I've played around with linear regression moving averages before and found them useful. Never come across the MSROC though. Will take a look.

    Adaptive Moving Averages

    Yeah, the MAMA looks interesting. Currently trying to figure out how to tweak the sensitivity of it. Any tips?

    Adaptive Moving Averages

    Yep. But the scale I'm looking at makes whipsaws untradeable unless you are a very quick witted local making on the spread. Hence to me it is just noise and I want to filter it. Thanks for your thoughts.

    Adaptive Moving Averages

    Take your point Bill. As I said though... "I need an AMA which will help me accurately identify market turning points." I am not relying on the AMA. I want a time lag as I am evaluating the market both before and after the turn. I am not interested in catching the exact moment of the...

    Adaptive Moving Averages

    Hi All, I wonder whether any of you have any interesting opinions on adaptive moving averages. I need an AMA which will help me accurately identify market turning points. As such I have no interest in the actual value of the AMA (it can overshoot as much as it likes) because I will only be...

    Orders executed above the ask and below the bid

    Thanks Trom, now we're getting somewhere and I'm learning something. I'm aware of the anachronism that is the trade-through rule and the arguments for and against it. Personally I think these days it's a case of buyer beware and if you aren't diligent enough to look at the book before placing...

    Orders executed above the ask and below the bid

    Indeed, the current reporting requirements are a joke. And given the amount of volume now going through these platforms, any idea of efficient price discovery is rapidly going out the window.

    Orders executed above the ask and below the bid

    Thanks. I did think that this might well be down to the late reporting of dark pool transactions. The SEC really need to put in place some sensible reporting requirements. Thankfully, it looks like they are finally realising this... SEC hints at regulation of dark pools

    Orders executed above the ask and below the bid

    Thanks for your replies but this isn't how it works. Using auspiv's example, the 20k market order would actually be split and the sequence of events would be: 1. Sale of 10000 @ 50.01 2. Ask lifted to 50.02 3. Sale of 10000 @ 50.02 The buyer would get 2 partial fills resulting in an...

    Orders executed above the ask and below the bid

    Thanks Gimp. Will do some reading up on third market.

    Orders executed above the ask and below the bid

    Watching the tape I can see sales that are being executed above the current ask and below the current bid. Could someone please explain to me the circumstances under which this happens. Why would a market order get executed at any price other than the current ask/bid? Thanks in advance.

    What's the difference between trader and portfolio manager?

    Entirely disagree. You are looking at scaling simply as increasing position size. You can scale in many more ways than that.

    What's the difference between trader and portfolio manager?

    I second that. One of the very rare threads that has something to genuinely offer on this site. Sjfan's logic is sound but I fear many who read this thread will just assume he is one of the institutionalised oldboys and dismiss his opinion because it flies in the face of their trading dream...

    How is "money management" for traders different from large fund management firms?

    This is the smartest single comment on the thread and in my experience the correct route to the answer begins down on the French Riviera. Forget using Kelly unless you are sat at a blackjack table. As has been stated here previously the underlying assumptions are fundamentally flawed when...

    Information - Us v. Them

    @Here2Learn You are making the same assumption as the vast majority of retail traders...that the large institutional traders are all making huge profits. This simply is not true. Many institutions (the banks in particular) make enormous losses on some of their desks. They just make cart loads...
