Are Bollinger bands legit or is it another TA woohoo nonsense?
>>
>>1041375
They are legit if enough traders believe in them. Really it's all just alchemy.
>>
>>1041375
do you know what you're looking for when using BBs? cause i find most people don't.

im looking at how on the bottom band near the minus sign and just before that, price visited this level later on. im also looking at the top bands touching 30. wouldn't be surprised to see 24 then 30.

though, i usually use a larger standard deviation
>>

no, not breaking the bands.

do you see the minus sign near the middle bottom of the pic? and then bottom band thats right above it? take a piece of paper and, being parallel with the rows, see how close the last close is to where the band made its most recent bottom.

Technical analysis works in the short term to a certain extent, but only because enough people accept its "rules" that they buy when TA says buy and sell when TA says sell.

Long term, it's a bunch of BS. The market always reverts to fundamentals.

I use bollinger bands while trading forex. Live. On a daily basis.

I use them to keep in mind what the higher timeframe is doing while I'm down in the 1 hour space.

Eg. In the one hour space I see an uptrend, with a small turn down. Buying oppertunity right?

Well with the 200 or higher bollinger band on I can see that that center line or the upper band is being approached. At 200 period we're effectively looking at 8 days worth of data. Without having to zoom out.

Quality of life thing mostly. I'd never actually trade off of it though.
>>
>>1042359
TA is like bullets, but the gun and the guy shooting it is FA.

If you're just doing FA, then sure you can kill someone. With great effort and much punching and possibly harm to yourself you can kill someone.

But with TA+FA, it becomes a lot easier to kill (get in and out at a profit) without hurting yourself.

With just TA... It's a bit weird. Sometimes you nail trades. Sometimes they go wrong and you don't know why so you start looking thinking:

"Hmmmm maybe this little trend line here should actually point HERE, and this little heads and shoulders is actually a really bent out of shape teacup".. Yeah That's how it should've been if i'd drawn that I woulda been profitable.

When really you're trying to long CAD in an oil turndown.
>>
>>1041375
they just measure standard deviation....

the use of them is naive at best - firstly if you're going to assume a normal distribution and start applying the central limit theorem you'd want your data to be independent... financial time series data doesn't have this quality, each entry is related somewhat to the previous and serially correlated. The assumption of normality is flase too - financial data is known to have fat tails. Lastly the sample size used is often too small to have any meaning.

Basically they're just fancy lines on a chart and like most 'technical analysis' just used by simple inumerate people who wan't an easy framework to help them make trading decisions because they don't know enough about statistics to do any proper forecasting themselves.
>>
>>1041438

'statistics made easy' for complete retards...

widely promoted by brokers as it is simple and easy to pick up and gives people a reason to place lots of short term trades

>The seeming simplicity of just using a chart with some indicators or lines attracts many beginners. It would seem like such a great shortcut. You don’t really need to do real work, just look at a chart. Throw in a few indicators named after some authors and you’re done. It’s a seductive idea, that you don’t really need to work hard. This is why the field is attractive to retail traders and that in turn is why it’s an attractive field for those peddling products based on colorful names and back stories.

Glad you made some money using it during one of the longest bull markets in history, though.
>>
>>1043260
Except that technical analysis is not devoid of work. Hell, indicators are not really part of classical technical analysis.
Professionals often disregard most of technical analysis because they have clients. Brokers need to buy or sell already certain amounts and they need to do so in a way that minimizes market impact (this is the main reason trends are generated). Also, those who profit from speculation often work in the short term because the longer the timeframe, the more factors are in play, such as macroeconomics, laws, regulations, politics, war, earnings seasons, etc. Short term speculation can be done with several tools, TA is one of them. TA IS statistics. A bar that is bigger than the last 80% of the bars doesn't arise by mere chance. Actually it does, but it's extremely uncommon. It's often generated by institutional pressure, either selling or buying pressure, and it will usually last for a while, since institutional players often have enormous orders to execute. Also, there's the expectation of all other traders (retail OR institutional) to be able to buy/sell after the surge at better prices. Why would I buy NOW something that has been falling with significant pressure? Unless there's a significant signal of a direction shift, I'll wait and buy lower. This is CROWD PSYCHOLOGY. TA is nothing but analysis of the markets' fears and expectations.

Now, indicators... Price action analysis is, by definition, devoid of indicators. Indicators are based on price. If you can read the price action correctly and infer which direction is more likely at any given moment, you don't need indicators. BB are supposed to capture something which is not easily seen: volatility. It's not an easy task to analyze, in real time, where price can probably revert direction. But I'll not buy just because price hit the lower band! I'll wait for a confirmation signal, something that shows me that selling pressure is gone, at least for a while.
Volatility is statistics.

Take this, for example. Disregard the colored lines, it's a volatility indicator which serves other purpose (StopATR).

I don't buy a hammer (or bull reversal bar) just because it's a hammer. It's not a kids game, for fuck's sake. I made this trade because it showed buying pressure at an level universally recognized as an interest zone: the previous day close.
>>
>>1043303
Also, you can see how price reacted against the previous day close the next day.
>>
>>1043303
nice that you don't show us the 100 "hammers" near "previous day closes" before that did not work
>>
OP, you need to understand what volatility means and how an indicator of volatility is supposed to be used.
You need to study price action. Period. Some beginners are attracted to indicators because they seem easy and simple, but price action is not simple. Al Brooks wrote around 3000 pages on it, go read it, just skip the first book (Bar by Bar).
Indicators are to a trader like a good pair of shoes are to a runner. It serves a purpose, but it's not the main source of the runner's work and performance.

Actually, classic TA came first, then a bunch of mathematicians came and created indicators, but no one but themselves knew how to use them. These days, most indicators are not used how their creators intended and most beginners pay most attention to the indicators than to the price.

it measures standard deviation of the observed moving average of the a specified time window.

though, to think that achieving 1 sd, isn't easier than achieving 2, i'd like to see your math. you'll have a 33% chance to hit either 1sd up or down, and like an 18% chance to hit a 2sd.

you're a fucking retard as suspected previously... you're applying the normal distribution to financial time series data

even though you're claiming to be using the normal distribution you can't even get the percentages correct... 95% of the data is within 2 standard deviations of a normal distribution and it isn't even applicable here....

you're linking to the central limit theorem but you still don't understand it and need a source???

independent data is a fundamental assumption you complete spastic... this is pretty basic:

you can read more here if you like:

https://en.wikipedia.org/wiki/Central_limit_theorem
>>
>>1043518
>https://en.wikipedia.org/wiki/Central_limit_theorem
In probability theory, the central limit theorem (CLT) states that, given certain conditions, the arithmetic mean of a sufficiently large number of iterates of independent random variables, each with a well-defined expected value and well-defined variance, will be approximately normally distributed,

note the line:

'independent random variables'
>>
>>1043520
now answer me this:

why is it wrong to use the bollinger bands as a means of measuring sd? after all, financial institutions do use the central limit theory, using financial time series data, which is dependent data.
>>
>>1043525
>why is it wrong to use the bollinger bands as a means of measuring sd

it isn't wrong to use them as a means of measuring standard deviation - they objectively do measure standard deviation... that is what they're plotting

it is just that taking a small (often meaningless) sample of 20 and then calculating the standard deviation is of very little value

taking it further and falsely assuming a normal distribution and asserting specific % values to the likelihood of a price reaching some level is especially naive and rather dangerous

financial times series have fat tails, assuming a normal distribution is just stupid...

I've already pointed all of this out in my first post on this thread

>>
>>1043528
price is always likely to hit a 1sd before hitting a 2sd.


https://en.wikipedia.org/wiki/Fat-tailed_distribution

In finance, fat tails are considered undesirable because of the additional risk they imply. For example, an investment strategy may have an expected return, after one year, that is five times its standard deviation. Assuming a normal distribution, the likelihood of its failure (negative return) is less than one in a million; in practice, it may be higher. Normal distributions that emerge in finance generally do so because the factors influencing an asset's value or price are mathematically "well-behaved", and the central limit theorem provides for such a distribution. However, traumatic "real-world" events (such as an oil shock, a large corporate bankruptcy, or an abrupt change in a political situation) are usually not mathematically well-behaved.

I prefer the Donchian channel. Bollinger bands move too much, balloon out weirdly and so on. The Donchian channel is more like an upper and lower limit (average), the way you'd expect BBs to behave.
