That sounds like a dream coming true! Automatable workflow by scripts, offline, possibly even usage of multi-CPU-cores without having to launch several instances to max out modern CPUs? Eager to see the presentation on Friday :-)

> As an aside -- I can't see new users taking advantage of Express Generator right away

Yes, you are right.

The Express Generator is for people that are not afraid to write commands in a black rectangle or to change numbers in text files with an odd extension.

However, if a geek wants to run 8 Generators on EURUSD at 01:30 in the morning. Then validate all of the exported collections on GBPUSD and merge them into another collection. And to repeat this on 10 different currency pairs only by settings a Cron job or a Task schedule... Just to see what their performance will be in a month... Big fun is coming.

Some very early examples:

Generating a new collection

Recalculated 4 Collections

Multiple scripts run with a click. Note: network = 0, disk = 0

...

Please join our meeting on Friday. Some surprises are always possible.

Nice stuff coming, eager to test it! What I am really interested in is the speed. Right now, EA Studios beats it all if being run on Thorium AVX2 builds from here: https://github.com/Alex313031/Thorium-AVX2/releases I wonder if Express Generator will be faster than that...

I'm glad to see that downloading Premium Data will be available shortly.  There was a time when I thought broker data was important -- but no longer.  The Premium Data is good enough and now I feel the more transparent and easy to download data then the simpler will be the work flow.

And from a purely selfish perspective, I would prioritize the "To Be Done" as follows:
- Data Horizon, Optimizer (I don't use Normalizer or Monte Carlo)
- Out of Sample
- 100% indicators support

As long as I can import a collection back into EA Studio then the other collection-related features are less important to me.  Also, choosing indicators seems kind of like overkill.  Does anyone really have any evidence that some indicators work better than others or that certain indicators should be avoided?  It seems to me that if the stats look good then it shouldn't concern the user which indicators are being used.  I understand why that would be important for FSB Pro because the quality and performance of Custom indicators can vary, but less so for EA Studio.

Popov -- this isn't intended to push you in any direction.  In the event that it is of interest to you to have another set of eyes priortize features from a user perspective, then I decided to take the opportunity to volunteer mine... 

I look forward to learning more tomorrow...

Added Data Horizon

Data Horizon options

; Data Horizon
max_data_bars   = 100000

use_data_start  = true
data_start      = 01 Jan 2020 GMT

use_data_end    = true
data_end        = 01 May 2022 GMT

A note regarding settings the dates.

If you set the date like this: "data_start = 01 Jan 2020", Node.js will use the Time zone of the local computer.

If you want to use GMT, you have to set the date as this: "data_start = 01 Jan 2020 GMT"

Acceptable format is also: "data_start = 01 Jan 2020 00:00 GMT". You can use also an exact hour if you want.

> 1. Is there an "official" link to download the latest / greatest version of Express Generator?

Please use the link I shared in the meeting.

> 2. To be clear -- this only affects the start / end dates of the data fetching.  It doesn't touch the OHLC time stamps, right?

Data Horizon options work for the Generator only. It cuts the data according to the used options.
You can see how it works in EA Studio.

You can use "use-data-start" or "use-data-end" or both together.

Hey Popov,

Getting express gen going and it is awesome!!

Got an issue trying to use data other than Premium though. When I try to validate using data from a different source i get the error shown in the screenshot

Hello sammjacks,

Would you consider sharing your my-settings1.ini file -- it would help me get a jump start on testing, as well.  And, if not, that is perfectly understandable...

Hey Sleythus, not sure how useful my files are as I am just starting to play around with setting things up myself but Ive sent them to you

Great, cheers Popov.

I have a general question regarding time settings. They are not implemented in express gen yet, which would be really useful for me.

I usually set my time settings to 01:00 - 24:00 in order to avoid opening positions during the high spread time (where the spread can be around 100 which would destroy profits).

I am getting a lot of strategies that perform very well for when I let them trade 00:00 - 24:00 but then as soon as I change the settings 01:00 - 24:00 the equity curves change completely to usually perform very poorly.

It also obviously makes it much harder to find strategies with these time settings.

Any discussion on this topic or different perspective would be great as I am currently a bit unsure if my approach is sensible.

Interestingly for a lot of the strategies (without a take profit), if I only let them open trades during 00:00 - 01:00 and set the spread to 100 they do really well.

I'm glad you find it useful!

Please make a video of how you use the program and with what settings. It will also be helpful for the other traders and me because I'll see your way and get ideas of how to make it even better.
