You can easily rise the limits by editing the Data source settings file.

The data source files are in the Forex Strategy Builder Pro\User Files\System folder.

The files start with DataSource_ . For example, the default data source file is "DataSource_FSB Demo data.json"

Near to the bottom of the file you'll find these records:

  "MaximumBars": 50000,
  "MinimumBars": 300,
  "MaximumBarsLimit": 50000,    <----- Edit
  "MaxIntrabarBars": 100000,
  "MaxIntrabarBarsLimit": 100000,   <----- Edit

You can edit the data manually when FSB Pro is stopped.

When you open the program next time, go to Control Panel -> Data Horizon and you can set your working settings there.

I know users that work with 1 mil bars, so it must work on your monster machine.

Please share the results.

My laptop almost died when I run the Generator with 1mil data.

A few years ago I used a lot of bars for a while.. and did not see any appreciable benefit. I guess there may be a benefit according to some people.

I take my ea and run it on different  time periods to get an idea as to curve fitting instead of a huge number of bars.

I found, when I was using a lot of bars that I had long periods when the strategy would not be trading but the numbers looked good.

There are a few ways to looking at the number of bars for generating, we have to determine our preferences

Thanks for the tip Popov but unfortunately I still couldnt figure out how to change maximum bars to 1,000,000.

Can you please send screenshots step by step with the Forex strategy builder professional on how to change the maximum bars to 1million? A picture is worth a 1000 words.Am sure a lot more people on your forum will benefit from the screenshots especially those new to the Forex strategy builder professional.Thank you..

You have to first stop FSB Pro and after that to edit the corresponding DataSource file. Please try it and report.

These errors must be due to your internet connection. I tested it now and it works fine.

Our Data Service provides up to 100 000 bars. You can import as many bars as you wont form your MT or from other sources.

Hi there,
I adjusted the max bar numbers in the corresponding data source file in System, restarted the FSB Pro program and adjusted the max number in Data Horizon, but when I went to download data under Data Download, the max number of downloaded bars is still capped at 100,000.  And I confirmed that my original data contains 300,000 lines or bars of data.  Please see screenshot of my adjustment, and please let me know what I missed.  Thank you!

Thank you for the update!

So data download is capped at 100 000 bars no matter what settings I adjust?  If so, then what do the updates in the system data source file and Data Horizon do?

Thank you Mr. Popov, I figured it out, it works now!

It must be able to load 5mil bars. However FSB Pro is more productive with a lower amount of bars.

Hello Popov,

I've just downloaded the software, started to use it, and join this great forum today. I see everybody are discussing about removing data bars limitations. I agree that we need to have access to significant amount of data (maybe around 35000 bars on M15 & M5 based on your experience) to develop a strategy. However, whenever I try to export  bars data from my broker by using "Export Data to CSV" script, it barely export more than 19000 for 1Min char and consequently lesser bars data on larger time frames. Also, it does not collect any data on weekly time frame. I would appreciate if you please advise.
