Interday market dynamics refer to the fluctuations in market prices over a period of several days or weeks. This is influenced by various factors such as global economic trends, interest rates, and geopolitical events.
Intraday market dynamics, on the other hand, focus on the short-term price movements within a single trading day. As we learned earlier, intraday trading can be affected by news events, order flow, and market sentiment.
Market participants often need to consider both interday and intraday dynamics when making investment decisions. By understanding these dynamics, traders can develop strategies to capitalize on market trends and mitigate risks.

Stock Trading Essentials
Intraday trading, also known as day trading, is a type of trading where stocks are bought and sold within a single trading day.
Day traders purchase and sell stocks between 9:30 a.m. and 4 p.m., when the exchanges are open, and all trades are settled at the end of the day.
For another approach, see: Day Trading vs Scalping
This type of trading appeals to investors seeking a quick profit from changes in stock prices, which can be influenced by factors like government job reports and cost-of-living updates.
Day traders can use margin loans to cover some of their costs, allowing for greater leverage in the market.
Historically, late-night or early-morning news has not had a significant impact on the financial markets, as day traders don't have to worry about it affecting their trades.
Intraday Trading Strategies
Intraday trading strategies are all about making the most of short-term price movements within a single trading day.
To succeed in intraday trading, you need to stay alert and adapt quickly to market changes.
One popular strategy is scalping, where you aim to make a profit from small price fluctuations.
Scalpers often use technical indicators like moving averages and RSI to identify potential trading opportunities.
Intraday trading also involves using charts to analyze market trends and anticipate price movements.
For example, a rising trend line on a chart can indicate a bullish market, while a falling trend line can signal a bearish market.
Another strategy is day trading, where you hold onto your positions for a short period, usually just a few minutes or hours.
Day traders often use momentum indicators like MACD to gauge the strength of a trend.
Intraday trading can be a high-risk, high-reward game, so it's essential to set clear goals and risk management strategies.
For instance, setting a stop-loss order can help limit your losses if a trade doesn't go in your favor.
Analysis and Discussion
Our analysis of TV exposure and its impact on mortality risk reveals some fascinating patterns. The geographical distribution of TV 0–7, interday TV 0–7, and intraday TV 0–7 shows that departments with higher interday TV were generally located in northwest France, while departments with higher intraday TV were mainly located in the south.
A time-stratified case-crossover design with quasi-Poisson regression was used to examine the association between mortality risk and TV indices. This design compares the exposure in the case period (the day of death) with exposures in control periods, which are the same days of the week in the same calendar month, year, and department.
The analysis controlled for daily mean temperature and daily mean relative humidity (RH) using distributed lag non-linear models (DLNM). The associations of mortality with TV indices were expressed as the percentage change associated with per interquartile range (IQR) increase in each index, with a 95% confidence interval (95% CI).
Derivation of Temperature Variability
Temperature variability (TV) is a measure of how much temperatures can change within a day or between days. It's calculated using the standard deviation (SD) of daily minimum and maximum temperatures.
The standard deviation of daily minimum temperatures and daily maximum temperatures within L days before the current day is used to define TV. This is also known as the intraday TV, which only considers temperature changes within the same day.
The interday TV, on the other hand, considers the variations between days. It's calculated using the weighted SD of daily mean temperatures during the past L + 1 days.
To calculate TV, we use the following equation:
TV0-L=∑(Tl,min-T¯)2+∑(Tl,max-T¯)22L+1
Where L is the number of preceding days, Tl,min is the minimum temperature on day l, Tl,max is the maximum temperature on day l, and T¯ is the average of daily minimum temperatures and maximum temperatures during the L + 1 days.
We can break down this equation into two parts: the intraday portion and the interday portion. The intraday portion is the sum of the variance of minimum temperature and maximum temperature on specific day l (VARl).
The interday portion is the multiples of the variance of daily mean temperatures (Tl¯) on the current day and preceding L days (VARtmean).
Here's a summary of the two parts:
By calculating the square roots of the intraday and interday portions, we can make their units comparable, allowing us to express the relationship between TV, interday TV, and intraday TV as:
TV0-L=TVinterday,0-L2+TVintraday,0-L2
Discussion
The geographical distribution of TV indices is an interesting aspect of this study. Departments with a higher interday TV were generally located in northwest, while departments with a higher intraday TV were mainly located in south.
The researchers used a time-stratified case-crossover design with quasi-Poisson regression to examine the association between mortality risk and TV indices. This design compares the exposure in the case period (defined as the day when death occurs) with exposures in the control periods.
The study found that the percentage change in mortality risk associated with per IQR increase in each TV index generally increased as the lag period increased. The percentage change for TV 0–7 was the highest among all lag periods.
TV indices were defined as TV 0–1 to TV 0–7, interday TV 0–1 to TV 0–7, and intraday TV 0–1 to TV 0–7. The associations of mortality with TV indices were expressed as the percentage change (%) associated with per interquartile range (IQR) increase in each index, with a 95% confidence interval (95% CI).
Here's a breakdown of the correlations among TV indices and daily temperature:
The associations between mortality and TV indices were more profound during the moderate season.
Conclusions
In the end, understanding the difference between interday and intraday trading is crucial for investors looking to make informed decisions.
Interday trading, also known as overnight trading, involves holding positions through the close of the market on one day and the open on the next. This type of trading requires a good understanding of market trends and volatility.
The key takeaway is that interday trading can be a good option for those who want to hold onto their positions for a longer period, but it also comes with increased risk due to overnight market fluctuations.
Intraday trading, on the other hand, involves buying and selling within the same trading day, closing out positions before the market closes. This type of trading is ideal for those who want to take advantage of short-term market movements.
As we've seen in the article, intraday trading can be a good option for those who want to manage risk and avoid overnight market fluctuations.
Frequently Asked Questions
Is it intraday or intra day?
The correct spelling is "intra day", which refers to price movements within a single trading day. Intraday is a common abbreviation, but intra day is the preferred term in the financial industry.
What is the meaning of inter day?
Inter day refers to the period between two consecutive days. It's a term used to describe the time span between days, often used in various contexts such as scheduling, planning, and data analysis
Which is better, intraday or delivery?
For beginners, delivery trading is generally safer and more advisable due to lower risk. It allows for a more relaxed learning pace without daily market pressure.
