I'm happy to announce Express Generator v2.67

This update comes with updated indicator formulas to better match MetaTrader5.
It is also 10% - 60% faster (performance gain depends on the length of the data series and the indicators used).
It prints the name of the exported collection file correctly.
Also, added new backtest stats metrics and the corresponding Acceptance Criteria:

Have a successful trading session!

Re: Express Generator - News and Updates

Big thanks for the update. For me, it feels at least 70% faster. It's insane how many strategies and parameters it can test in such a short period of time. Amazing work!

Re: Express Generator - News and Updates

Helo Traders,

I just uploaded Express Generator v2.68

This release includes new fetch parameter: --if-missing-or-older-than = 0
It accepts time in minutes.

This parameter is useful to prevent frequent data download when we run the fetch command automatically.
If it is set, it will prevent subsequent file download if a current data file exists and is updated recently.

; This option is helpful to prevent frequent downloads of data files.
; It accepts time in *minutes*, where 0 means the option is off.
; Example: if_missing_or_older_than = 60
;   It will download new data file if the current file is missing or not updated during the last 60 minutes.
if_missing_or_older_than = 0

Example:

https://image-holder.forexsb.com/store/exgen-if-missing-or-older-thumb.png

It fetches the files the first time.
Then I run the fetch again with adding M1 period.
It skips the existing files because are fresher than 60 minutes and downloads the M1 file only.

Have success with your trading and a lot of fun!
