On-line Data size calculator

We have prepared a simple on-line data size calculator for AmiBroker here:


that gives you some idea how much disk space you need for the database with given number of symbols, retention length and interval. It also gives absolute minimum free RAM size required to process one symbol data of specified length and interval.

This calculator has been created because many people don't do the math and have unrealistic expectations. More information http://www.amibroker.com/guide/x_performance.html and http://www.amibroker.com/guide/h_multithreading.html


Very nice utility - May I please make a suggestion - you may want to allow the user to spicify the duration of trading in a day - as the utility in its present form seems to presume trading for 1440 minutes - 24 hours, however most of times trading happens for fewer hours

For example, here in India - mostly trading happens for around six hours (Except for Commodities)

Again - thank you very much for the nice tool to see reality.

With Regards

@Tomasz Nice tool.. Thanks

DIY! If you do the calculations yourself, the essence will stick to you at all times. :slightly_smiling_face:

That is all we need to know! Kindly read Tomasz's post again. Quoting him in case you missed reading:

If your exchange trades only 6 hours per day, you can divide the result by 4.

Very good idea, thank you Tomasz.
