The Electric Day Trader and Ruin. How probability oppposes short-term investors.

  1. you have clearly never traded nor have you read the article in full. So what exactly do you base your utterances on? And what do you mean with "if you are both reasonably cautious and lucky"??? If you play sufficiently often then this has nothing to do with being cautious or lucky.

    The article is twisting the truth to let the author make his weird point: A system with a positive edge has a nearly 100%probability of ending up in the money when employing the right position/bet size. How do you want to argue against that?

  2. Natural price oscillations aren't based in math and do not need to be calculated using math.

    When you view price movement on time, tick or range based charts you MUST HAVE statistical data in order to make any sense out of it's movement BUT using time, tick and range based charts are like looking though an opaque lens to drive a car. You can see something is out there but can't quite get a solid grasp of it.

    What, do you need an interpreter to understand what to do at a red light? Not no but hell no. Clear the garbage off your chart and look at what pure price movement does with perfect consistency. Trading is only gambling if you can't see what you are doing.

  3. what's weird about making a bona fide attempt to make some money for yourself, per se ? vs enriching your broker only

    long run . . . what about it? as keynes famously said, in the long run we're all dead

  4. "Electric," you say? I got a real jolt out of that one.

  5. You know the mentality you are dealing with when you see that useage instead of "Electronic".
    Like the pit traders are reading their trades using candles and reading prices on chalk boards.

  6. true, you don't have to use mathematical definitions to see what's going on with price. (like some people have tried to do, for example kaufman in his skew-kurtosis strategies - look at shape of price distribution to see what's going on, but i don't know if it really work)

    there are other ways of doing it like moving averages, various standard deviation ideas, atr/kettler channels etc

    i guess we're not arguing about whether technical analysis works or not. it probably does help a picture is worth a thousand words

    the issue in this thread is how frequently you trade, and at want point the frequency of your trades begins to work against you

  7. Perhaps by "electric," the author was referring to traders who are more "plugged in" to what's going on and are therefore more "current."

  8. Lol...is that what they assumed? I didn't even read the junk. These are morons and the problem is our kids PAY to receive education from them.

    I know people who day trade for years and have made a lots, I mean a lots of money. Not easy, but flying a jet fighter is not easy either. Only people good at their profession make money. The rest lose either money or time, which is money of course, or both, which is everything.

    Jerks..

  9. reasonably cautious: try to find optimal position size, % of equity you risk on a trade.

    "reasonably" means if your bet per trade is too small, you're not moving anywhere

    "cautious" means if your bet per trade is too large, you're increasing your risk of ruin

    "reasonably cautious" means finding the right tradeoff

    lucky: we don't have an infinite series of trades. lucky means being lucky, as it were, to have your theoretical edge realized, over the course of the limited series of trades.

    that's why this risk of ruing thing is so important. yes, it's unpleasant for some of us to even think in those terms. trading does not always have to be about pleasure, no pain no gain

    lucky means having the courage to say: i know i can be wiped out by a series of losing trades

    all this should be balanced, but i don't know how, quite frankly.

    that's why i don't trade regularly, it's true

  10. yes, some traders really are a little eclectic and there's nothing wrong with that
