TALES! TALKS! TALKS!

 
Karputov Vladimir:

What I meant to say was that prices come in a price stream. This flow could be something like this (it's essentially a clipping from a tick chart):


But when this stream is rolled up into timeframes - you get completely different views/figures (it all depends on your imagination) on different timeframes. But collapsing data into timeframes kills something in the data. Something very important.

The price stream is discrete by nature. It is not an analog signal that was violently discretized in candlestick bars.

The pure price stream has the same shapes seen on candlesticks.

It is quantised in levels but not in time.
 
Alexey Volchanskiy:
It is quantised by levels, but not by time.

And the minimum level value will be equal:

SymbolInfoDouble(Symbol(),SYMBOL_POINT);
 
Alexey Volchanskiy:
It is quantized by levels, but not by time.

И? - in terms of time, do you think the price flow is continuous?

 
Andrey Dik:

И? - in terms of time, do you think the price flow is uninterrupted?

Wrongly phrased, naturally quantised and in time, but not at a constant sampling rate.

Of course.

An analogue signal is a continuous function that has values throughout its definition. Also, an analogue signal has a derivative at any point. The same cannot be said of price. The price changes not only with minimal steps with the value of Point(), but also with random intervals between changes of its value, i.e. it is a stepped (and therefore discrete) function without discontinuities (its value can be obtained at any moment). Thus, the price function is continuous, but discrete.

Any price processing including the most sophisticated DSP is an attempt to "analogize the price" and decrease the noise. Candlestick construction has the same goal - to reduce noise.

By disabling visual mapping on the chart (starter idea )- we get noise in its purest form. Cool, great for lovers of all things natural, but very lame for those who try to analyse information for profit.

Candles were invented in Japan in the 17th century by a merchant who sold rice at the stock exchange of that time. Yes, there were already analogues of stock exchanges back then. And the purpose was not to get rid of noise, but to have a clear picture of trading history.

The candlesticks do not get rid of noise, on the contrary, they give false data. Open and Close take the values of quotations which can be absolutely different from the general trend. But people did not know about this in those years. But nowadays 99% of traders do not know about it either and try to play around with figures).

It's not about what it was in the 17th century, it's about the starter's suggestion to use a pristine chart, instead of price information. Don't like candles - you can display price data in other ways, the ways are only limited by imagination and driven by goals in extracting information. There is no information on a blank chart, and therefore there is nothing to analyze. In the 17th century they tried to analyze prices, but in the 21st century, when ships are sailing in the big theatre, people don't want to analyze anything.

In the 17th century at least someone tried to analyze prices, but in the 21st century, with ships crossing the vast expanse of the big theatre, people do not want to analyze anything.
I also wrote that you can just put a vertical slider, the chart is not needed. And we switched smoothly to candlesticks later).
