I leave mine running all week on the 28 major/cross pairs, and then swap strategies in or out on weekends for the next week. I have a dedicated server with a Ryzen 5900X (12 cores, 24 threads), so it has enough horsepower to just churn out strategies every day. It's a single one-click command that opens all the instances. Very convenient!

Thank you. Will keep in mind. Right now to be honest Lisa's post helped to speed up using Express Generator. Just needed to tune a bit with advice given thus far. You are also right the '/' or '\' not an issue.

I've replicated Lisa's advanced script with pair am interested to look at using the Premier data for time being.

Am also trialing Tick Data Manager from one of Lisa's video to do further optimization testing on tick data.

Attached image is where am at.

Script is following Lisa's one from one of her blog post.

The template is from Lisa's blog post. The '\' works . So definitely was not an issue.

In same directory C:\express-generator, I created a script called step_2_generate_strategies_v2.cmd. The contents of the file is

node ./bin/gen.js --settings gen.ini

pause

When I double click it, it gives the error

Cannot read settings file: gen.ini per the image I attached previously

Perhaps I don't need to add the caret in an .ini file in comparison to adding a caret in the actual script except at the end of line ?

Any clues

Aaron, you are correct.

The "\" separator is native for Windows, and the "/" separator is native for Linux and MacOS.
However, "/" works for all of them.

Hi I tried this

Unfortunately I get this error from the image attached.

gen.ini is in directory C:\express-generator\

Thank you. I definitely missed this one. Finally works as per attached image.

Will check if working with the file gen.ini gives any success, Also had it twice in gen.ini

That's what I prefer actually actually 

node ./bin/gen.js ^
