In other words, with time-series and sometimes panel or logitudinal data, autocorrelation is a concern. Negative autocorrelation occurs when an error of a given sign tends to be followed by an error of the opposite sign. For instance, positive errors are usually followed by negative errors and negative errors are usually followed by positive errors. We will perform an additional statistic test called the Durbin-Watson DB test that also diagnoses the existence of serial correlation.
The DB statistic lies in the 0—4 range and its interpretation is the following:. Essentially, the closest to 2, the lowest the serial correlation is. Results are in line with the Pearson autocorrelation test, which gives strength to the narrative that tick bars display a slightly lower autocorrelation than time-based candlesticks.
Another statistic we can look at is the normality of returns, this is whether the distribution of our log returns follows or not a normal a. There are several tests we can run to check the normality — we will perform 2 of them: the Jarque-Bera test , which tests whether the data has the skewness and kurtosis matching a normal distribution, and the Shapiro-Wilk test , which is one of the most classical tests to check if a sample follows a Gaussian distribution.
In both cases, the null hypothesis is that the sample follows a normality. Two cryptocurrency pairs Stellar and Zilliqa seem to actually follow a Gaussian if we set our significance level at 0. Fair enough, some of them could look Gaussian at least visually. However, notice that the number of samples n is very small e. In fact, a quick look at the CryptoDatum. Mystery solved? Non-normality of returns seems to be the rule regardless of bar type.

In this article we will learn how to build tick bars, we will thoroughly analyze their statistical properties such as normality of returns or autocorrelation and we will explore in which scenarios these bars can be a good substitute for traditional time-based candlesticks. In order to illustrate the applicability of tick bars in the forecasting of cryptocurrency markets, we will base our analysis on a whole dataset comprising 16 cryptocurrency trading pairs including the most popular cryptoassets such as Bitcoin, Ethereum or Litecoin.
Tried both types on the charts and OHLC bars appears clearer to follow. Trying to narrow down the number of charts I have to keep track of. I prefer volume charts, though I did at one time use tick. I think of it like a punch. Tick chart is like a jab, just one pop predicated on price. If you set your tick value high enough you will capture a lot of jabs which is more telling painful than a fewer number. The jabs are never consistent in force or speed per se, so it can be misleading as to the true nature of the guys power in his strong hand underlying market interest.
Whereas with tick, and time it could be anything, thin market, market maker bullcrap, news, bad print, or a real move. Plot the 3 charts overnight on one of the emini family and see which one is more readily discernible as to nature of the move. Its harder to play games when their size is on the table and cvb makes the "trend" if there is one, more discernable.
But whatever works for you, works. Nothing wrong with minute bars. If you are profitable stay with it. ProfLogic among others has written volumes on this. Good stuff and well worth a re-read As far as candles vs ohlc, I like the visual of candle and my feeling is if you understand them you can get an almost emotional sense of the market particpants.

An example might be an 18 ticks range bar chart on crude oil. If the market is moving fast, reports have come out or there is heavy volume in the market, the traditional 5 minute chart will need 5 minutes to complete the next bar before it provides you with a signal…if you have day traded futures before you know what 5 minutes can do to these markets…. The volume charts or range bar charts in this case will complete the bars MUCH faster because there is strong price action and strong volume and will be able to provide a signal faster than the time charts.
On the flip side, there are times when the market is dead…low volume, sideways, choppy action. If you are using the 3 minute chart and a moving avg.

Volume charts serve to blend and smooth out staccato price action of time-based charts.
Dull periods of listless price action mixed with high-volume spurts on any time-based chart will show as consolidation and spikes. That likewise tends to smooth out various chart tools such as moving averages and oscillators.
Volume charts tend to give clearer points of reference for measuring trend lines, channels, patterns and retracement studies. In other words, if the ER2 price moves from Within that series of five hundred price changes would be an unknown quantity of volume. Cross comparison of a tick chart measuring ES price changes versus a volume chart measuring 5, contracts traded shows a very parallel path of price action. Most of the time you will see tick charts and volume charts of relative measure matched up very near one another.
It could be said that the average contract size per price change in ES this day was ten contracts. Of course, high-volume days versus dull or abbreviated holiday sessions will skew this equation greatly. At this point in my career trading the eminis intraday, I find the most clarity and value inside tick or volume based charts. You might see more clarity and smoothness of price action measurement in these times of sideways chop interrupted by sudden program-trade slams. A slightly different view often provides an entirely new picture to work from.

Tick charts use the same data as time based charts. You are seeing the same thing, price, but shown differently. With time based charts, you need to wait N number of minutes before the bar closes. This can often times have you miss large moves or at least have you needing a bigger risk on the trade. The issue with Forex is that there is no centralized exchange so real tick readings are impossible. I get it, many people only have enough capital to trade the spot Forex market and not actual futures.
There is nothing stopping you from using currency futures to chart the price movement and then using your spot account to place the trade. The tick chart, hands down, give you a much better view of the price action. The high of the day on the 10 minute time chart appears as momentum. However, if you look at the highs on the tick charts, we have increased volume without further price advancement. The time based chart would be a tough day trade scalp but plotting the tick chart, trading a support break at highs, gives 20 pips.
Remember in Forex, 20 pips, depending on your lot size , can be a small gain or a large gain. Tick charts are unique in that they will only plot when the desired number of transactions take place. Ultimatly, your choice of tick setting will be the deciding factor. Again, that depends on you but note that lower settings can equal extremely fast price moves that you are unable to trade.
Deciding on the tick number is hit and miss. Many traders simply use Fibonacci numbers to determine the setting: , , , ….. You can have a high tick chart setting for setups, for example, and dial into a lower tick setting to determine entries. Trading with price patterns is, in my opinion, easier with tick charts as the price movements are cleaner and easier to read. The key, as is with all trading, is to test what you are doing.

Today, I decided to touch more on an educational feature rather than provide a certain market outlook. Many of my clients and blog readers know that when it comes to short-term trading I am a fan of using volume charts, tick charts, range bar charts and Renko charts rather than the traditional time charts like the 1 minutes, 5 minutes etc. My rule of thumb is that if you as a trader who makes decisions based on charts that are less than 15 minutes time frame, it may be worth your time to research, back test and do some homework as to potentially using other type of charts like volume charts, Range charts etc.
Volume charts will draw a new bar once a user defined number of contracts traded. An example is the mini SP 10, volume chart which will draw a new bar once 10, contracts are traded. An example might be an 18 ticks range bar chart on crude oil. If the market is moving fast, reports have come out or there is heavy volume in the market, the traditional 5 minute chart will need 5 minutes to complete the next bar before it provides you with a signal…if you have day traded futures before you know what 5 minutes can do to these markets….
