I am trying to build an excel model with several files of 200 MB eahc one and all toghether will reach at least 10 GB size.

 

I can't open more than 500 MB , i have al I7 processor and 16 GB RAM. Does anybody know what version of excel is better?, i began with 2007 , now i just changed to 2010 but i have more problems.

 

When i try to insert a new column excel says there are not sufficient resources, r something like that

 

Should I use the 64 bit version of excel?

 

On the other hand, Windows XP or windows 7?

 

Please i need help

 

Many thanks

Maybe try importing your data into an SQL database. Some options to consider are:

 

  • SQL Server Express (free with restrictions) or SQL Server (pay) by Microsoft
  • MySQL by Oracle (free with restrictions)
  • PostgreSQL by an Open Source Community (free with no restrictions)

 

SQL Server Express may be the easiest for you.

 

Make sure you backup your source data!

I do not have enough expertise in Excel to answer your question. However, I do have enough experience to communicate that I second the above posters comments that this would be much better suited work for a SQL database. I personally use MS SQL Server for my data repository, and am quite pleased. The other databases the above poster identifies would work as well. Although the code for the statistical math components is more difficult to generate in SQL, the database is very efficient in handling very large data sets. Also, Ad Hoc reporting of your data is very simple using a SQL database. I have a system at work that performs about seven million updates every day on hardware inferior to yours without any issues at all.

Many thanks for your comments. I don´t know anything about SQL programming. So which one of these softwares would you recommend to me? how much time do you think it would take to reach the minimum level required to do the same as anyone can do using excel? There is one easer and simple than others at using math formulas.

 

Thank you

definitely 64 bit of everything --- 64 bit OS, 64 bit excel, lotsa RAM

 

the latest excel can open a million rows of data

I think you can continue to use excel by simply adding horsepower to the equation, however in my opinion, it will not do it efficiently and that is why it is necessary to continue to ramp up your hardware. Do not get me wrong, I use excel every single day to perform functions for which it is well suited, but I also know what other systems (databases) do well and rely on them when they are more efficient.

 

To answer your questions:

 

So which one of these softwares would you recommend to me?

 

I have not used all available database software, so I cannot comment on which is the best, and they all do something better than others, but I have chosen MS SQL Server to accomplish my database tasks. It is robust enough for my purposes, and is easy to create databases and tables, import data, manage data, and manipulate this data. It is the one database that is tightly linked to Excel in case you wish to import/exprt data to from excel (which I do).

 

how much time do you think it would take to reach the minimum level required to do the same as anyone can do using excel?

 

I cannot answer this as I do not know what you are doing with Excel. Excel truly does a good job at quickly summarizing data in a mathematical and statistical sense. It has many built in functions to perform this work. I myself have custom code working in my Excel spreadsheets that I find very useful. SQL coding is similar to building custom formulas in excel. The good news is if you do not know how to code in SQL, you can find hundreds of examples on the internet that work with little or no modification. To give you an example, once you learn how to perform basic data manipulation in SQL (which could be accomplished in a day or two (IMO), if you are computer savvy), it takes me about as long to code a custom formula in Excel as it does for me to write SQL code for the formula. The main difference is SQL allows for a lot more flexibility in how my data is displayed and grouped, and it is much more efficient when dealing with large data sets.

 

Is one easier and simple than others at using math formulas.

 

I do not know which one is easier or more simple for math and statistics, as I think each have a similar baseline for achieving this goal. I use MS SQL Server due to it being less complex to perform the functions I require in a simple and efficient manner. We mainly use Oracle at work, and other systems that I work on a weekly basis include PostGres and MySQL, but at the end of the day, I prefer to use MS SQL for my purposes as I can manipulate the data faster (import, export, create databases/tables, etc.) than I can with the other systems. Also, I prefer the GUI of MS SQL, for managing and manipulating data than the other programs, although I am sure others would have a different opinion.

As the previous poster mentioned, the lightweight version of MS SQL is a no cost solution.

 

In the end, you can accomplish what you are looking for on anything from paper and pencil, a spreadsheet, or a database, it just depends on the amount of efficiency you are expecting.

May be time to ditch Excel and move to better suited Statistical Packages. R is one of them. Free and lots of addons.

    • Be careful who you blame.   I can tell you one thing for sure.   Effective traders don’t blame others when things start to go wrong.   You can hang onto your tendency to play the victim, or the martyr… but if you want to achieve in trading, you have to be prepared to take responsibility.   People assign reasons to outcomes, whether based on internal or external factors.   When traders face losses, it's common for them to blame bad luck, poor advice, or other external factors, rather than reflecting on their own personal attributes like arrogance, fear, or greed.   This is a challenging lesson to grasp in your trading journey, but one that holds immense value.   This is called attribution theory. Taking responsibility for your actions is the key to improving your trading skills. Pause and ask yourself - What role did I play in my financial decisions?   After all, you were the one who listened to that source, and decided to act on that trade based on the rumour. Attributing results solely to external circumstances is what is known as having an ‘external locus of control’.   It's a concept coined by psychologist Julian Rotter in 1954. A trader with an external locus of control might say, "I made a profit because the markets are currently favourable."   Instead, strive to develop an "internal locus of control" and take ownership of your actions.   Assume that all trading results are within your realm of responsibility and actively seek ways to improve your own behaviour.   This is the fastest route to enhancing your trading abilities. A trader with an internal locus of control might proudly state, "My equity curve is rising because I am a disciplined trader who faithfully follows my trading plan."

    • SELF IMPROVEMENT.   The whole self-help industry began when Dale Carnegie published How to Win Friends and Influence People in 1936. Then came other classics like Think And Grow Rich by Napoleon Hill, Awaken the Giant Within by Tony Robbins toward the end of the century.   Today, teaching people how to improve themselves is a business. A pure ruthless business where some people sell utter bullshit.   There are broke Instagrammers and YouTubers with literally no solid background teaching men how to be attractive to women, how to begin a start-up, how to become successful — most of these guys speaking nothing more than hollow motivational words and cliche stuff. They waste your time. Some of these people who present themselves as hugely successful also give talks and write books.   There are so many books on financial advice, self-improvement, love, etc and some people actually try to read them. They are a waste of time, mostly.   When you start reading a dozen books on finance you realize that they all say the same stuff.   You are not going to live forever in the learning phase. Don't procrastinate by reading bull-shit or the same good knowledge in 10 books. What we ought to do is choose wisely.   Yes. A good book can change your life, given you do what it asks you to do.   All the books I have named up to now are worthy of reading. Tim Ferriss, Simon Sinek, Robert Greene — these guys are worthy of reading. These guys teach what others don't. Their books are unique and actually, come from relevant and successful people.   When Richard Branson writes a book about entrepreneurship, go read it. Every line in that book is said by one of the greatest entrepreneurs of our time.   When a Chinese millionaire( he claims to be) Youtuber who releases a video titled “Why reading books keeps you broke” and a year later another one “My recommendation of books for grand success” you should be wise to tell him to jump from Victoria Falls.   These self-improvement gurus sell you delusions.   They say they have those little tricks that only they know that if you use, everything in your life will be perfect. Those little tricks. We are just “making of a to-do-list before sleeping” away from becoming the next Bill Gates.   There are no little tricks.   There is no success-mantra.   Self-improvement is a trap for 99% of the people. You can't do that unless you are very, very strong.   If you are looking for easy ways, you will only keep wasting your time forgetting that your time on this planet is limited, as alive humans that is.   Also, I feel that people who claim to read like a book a day or promote it are idiots. You retain nothing. When you do read a good book, you read slow, sometimes a whole paragraph, again and again, dwelling on it, trying to internalize its knowledge. You try to understand. You think. It takes time.   It's better to read a good book 10 times than 1000 stupid ones.   So be choosy. Read from the guys who actually know something, not some wannabe ‘influencers’.   Edit: Think And Grow Rich was written as a result of a project assigned to Napoleon Hill by Andrew Carnegie(the 2nd richest man in recent history). He was asked to study the most successful people on the planet and document which characteristics made them great. He did extensive work in studying hundreds of the most successful people of that time. The result was that little book.   Nowadays some people just study Instagram algorithms and think of themselves as a Dale Carnegie or Anthony Robbins.
