This feature was broken in several previous releases because I added "stricter" validation of the parameters having only the Generator in mind.

Now, it works again.

; Periods to download
; Example: period = M5 M15 M30
period = M30

So I thought it was possible to have multiple periods in the settings ini file.

I fixed this issue in Express Generator v2.50

Thank you for the report!

The settings files currently do not support multiple values. You have to set the periods as arguments to the "fetch" command ass follow:

node .\bin\fetch.js --periods M5 M15 M30 ...

I'll add this feature to the settings file later.

Thank you for the report!

Here is my Historical_Data ini file settings:

Here you can see the data is fetched:

When I put M5 M15 in my Historical_Data ini file it will NOT fetch the data as shown:

Here is my Historical_Data ini file settings:

Here you can see the Historical_Data ini file cannot be read:

I tested it just now with your settings, and it found 300 strategies in 30 seconds.

My test parameters are:

node ./bin/gen.js --symbol EURUSD --period M15 --max-data-bars 200000 --use-data-start true --data-start -365 --use-trade-start false --data-start-percent 0 --data-end-percent 100 --initial-account 5000 --leverage 50

Please check if there are no other parameters involved.

I have uploaded version 2.49 of ExpressGenerator.  Now the most recent historical data date for EURUSD is Oct 13, 2023 which corresponds to when version 2.48 was updated.

Here are my settings:
max_data_bars = 200000
symbol    = EURUSD
use_data_start  = true
data_start      = -365
use_data_end    = false
data_end        = "01 Sept 2023 00:00 UTC"
use_trade_start = false
trade_start     = "01 Jan 2017 00:00 UTC"
data_start_percent = 0
data_end_percent   = 100

It depends on your data_start variable. I'm doing 10yrs for example.

EDIT: nevermind, I guess you were talking about the end date and not the start date.

Here are my settings:
max_data_bars = 200000
symbol    = EURUSD
use_data_start  = true
data_start      = -365
use_data_end    = false
data_end        = "01 Sept 2023 00:00 UTC"
use_trade_start = false
trade_start     = "01 Jan 2017 00:00 UTC"
data_start_percent = 0
data_end_percent   = 100
