Hello all

I tried to make a Multi Market validation workflow that will pass a strategy if it passes validation on x amount of markets.
For this I made a node js script with AI.

Disclaimer, I did not test this thorougly yet. Use at your own risk.

- Put MultiMarket.mjs in bin folder.

- You need to have an input folder with singular strategy collections. Use auto_save_at_collected parameter when generating    a batch you want to validate MM on and output_replace = false.

- It will run Multi market validation on pairs which are also in eastudio.

- If you choose --markets 8 it will choose the first 8 pairs like on the website

- You can also choose your own list use these parameters for that;
--custom_markets true --custom_markets_list "EURUSD,USDJPY,AUDNZD,NZDCHF"

- validation_limit is the amount of markets it should pass to be valid.

- validated files should be in your output folder + /validated

Example:

set "symbol=%1"
set "period=%2"
set "startdate=%3"
set "enddate=%4"
set "timer=%5"

REM |Generate Normally
node .\bin\gen.js ^
 --settings                   wf_start.ini ^
 --symbol                  %symbol% ^
 --period                 %period% ^
 --data_start             %startdate% ^
 --data_end                  %enddate% ^
 --max-working-minutes    %timer% ^
 --output              ./collections/coll_[server]_[symbol]_[period].json ^
 --auto_save_at_collected  1 ^
 --output_replace  false

REM | Validate Multi Market
node .\bin\MultiMarket.mjs ^
 --settings               wf_MultiMarket.ini ^
 --symbol                   %symbol% ^
 --period                 %period% ^
 --data_start             %startdate% ^
 --data_end               %enddate% ^
 --input                  ./collections/ ^
 --output                 ./collections/MultiMarket ^
 --markets                8 ^
 --validation_limit       4

So in this case it will go through 8 market pairs validations and the strategy needs to be valid for 4 pairs.

I hope people can use this. If you find this of use please share a nice workflow with me since I still struggle myself.
