    Trading Journal, January

    because you need those extra $300 to cover your losing days. or, to put it another way, if your goal is to average $500 a day, then walking away after hitting $500 will make you fall short of your goal in the long term. - jaan

    has IB raised commissions?

    anybody else noticed that (some?) SUPERSOES fills now cost considerably more than $0.01? here's an excerpt from our account statement: buy 600 VRST @ 18.56, BEST: 380978 P VRST ... SUPERSOES 100 18.5200 -1852.00 -10.50 380979 P VRST ... SUPERSOES 100 18.5300 -1853.00 0.00 380981 P VRST...

    A question about indicators

    no, i don't know how exactly it is calculated, but visually it comes across as if a simple low-pass filter has been applied to RSI (just look at how it lags RSI). anyhow, i doubt that RSX is any better than RSI+filter. - jaan

    Effect of Decimalization

    FWIW, in our (day)trading, decimalization has not had any measurable effect. what has, however, is the volatility contraction: stocks move MUCH less (both pointwise and %-wise) than they did a year or two ago. (i can only speak about NAZ though.) our group started system research in early...

    Horror Stories

    my company is a Datek customer as well. while i cannot really complain about the executions (we've done about 700 round-trip trades so far), i agree with previous posters that their overall service leaves a lot to be desired. to me it looks like, more often than not, their problems are caused...

    Let's talk probabilities.

    heheh, somehow i believe you are overestimating the age of the stock market :) - jaan

    Let's talk probabilities.

    well, i use custom tools. you see, i'm a co-owner of a software house, so part of our "trading business plan" has been to convert our programming expertise (which we have plenty) to trading profits. - jaan

    Let's talk probabilities.

    well, sort of. then again, in short timeframe you don't really need much of an edge to be decently profitable. - jaan

    My History on Elite Trader for those who care ...

    well, that's most certainly not true. otherwise you could make a killing using today's high as your profit target, and having about 85% winners (dependig on your stoploss level). - jaan

    Let's talk probabilities.

    i don't think that's true in general sense. as i mentioned on tony's thread, i've done extensive analysis of setup probabilities in the last three years, and i've yet to see non-godmode (ie realtime) setups with historical probabilities greatly over their random counterparts. to put it...

    My History on Elite Trader for those who care ...

    yup, that's excatly where i was getting at with my question. perhaps i misunderstood him, but tony made it sound as if the close at top 10% was a bullish sign in this particular case, but in general case it clearly is not. so it would have been interesting to have him elaborate on this. - jaan

    My History on Elite Trader for those who care ...

    FWIW, while awaiting for your reply to my previous message, i took the liberty of performing a simple experiment on SEBL historical EOD data since 1996. the results were pretty much what i expected them to be: 1. stock closes at top 10% of range (202 samples) next open higher than today's...

    My History on Elite Trader for those who care ...

    wow. since you gave so precise probability number i would really like you to elaborate. are you saying that, historically, if a stock closes at the top 10%, then it will close (or open) higher next day 85 times out of 100? or are you merely saying that the next day's high would be higher than...

    Gunslinger Day Trading System

    DT-waw, i'm not sure i want to continue arguing, because you and i seem to be talking about completely different subjects. for example: 1. system optimization in my interpretation is NOT "adding parameters". instead, optimization is finding optimal values for given set of parameters...

    Gunslinger Day Trading System

    DT-waw, although ArchAngel already answered for me, let me give you another example how to over-optimize a system over large number of trades: let's assume we have a system that averages 10 trades a day over one year of historical data. that's about 2500 trades. now, we just divide the...

    Gunslinger Day Trading System

    that's not true, really. as an (admittedly contrived) example, if your system has N potential trades to pick, you can apply N binary parameters that tell whether to take n-th trade or not. after some "optimizing" you end up with the ultimate performance: the system picks only winners...

    Confession

    nicodemus, although i would not condone what you did, i just want to tell you that your witty comments have made this board much more enjoyable (at least for me). so please continue participating -- under a new alias, if you feel that'd be more appropriate. - jaan

    NQ-ES Shorts Easily Available?

    voodoo, excellent points. i take back the ownership vs contract argument. so, to rephrase you, the fundamental difference between futures and stocks is that in case of futures each transaction (virtually) creates a new contract, whereas in case of stocks the amount of available contracts is...

    NQ-ES Shorts Easily Available?

    ArchAngel, thanks for the long explanation -- very informative. but i stand behind my point: there is a fundamental difference between buying stock and buying a futures contract. after you have bought stock you actually own part of the company. after buying a futures contract you "own"...
