Downloader will not allow more than 1 thread

Downloader will not allow more than 1 thread

I'm trying to use the default "LSE - UK - EOD data" downloader, but I cannot increase the number of threads beyond 1. The up and down arrows next to the box don't do anything, and whatever I type into the box is immediately changed back to 1 when I click somewhere else.

Is this a bug? Or a limitation of the shareware version?

Thanks for any help

Hi Simon,

The maximum number of threads is defined in the downloader settings.
You can update this by following the next steps:
- Select the downloader
- Click on "Update"
- Click on the "Download Settings" button (at the bottom)
- Update the maximum number of threads field

Thanks Simon, you asked very important thing, and thanks to QS for the prompt reply. I have another doubt, how many threads we can use at a time? I tried 93, it took and could download data very fast, but later it was showing 16.Does this mean it can max take 16 threads? Another question is that, if I am using a script to run the downloader (say google sacipt to get 1min data for NSE stocks) automatically after every few minutes, how do I ensure that it is using say...16 threads at a time?

Currently:
- Maximum number of threads: 16
- Maximum threads when downloading data using a script: 1

Next release:
- Maximum number of threads: 20
- Maximum threads when downloading data using a script: 20

The script will use the downloader thread settings.

Are these numbers still the same ? Or can I use more than 20 threads now ?
