Re: Connect EG to my Historical Data
Express Generator can download data only from the data feeds we provide eon our servers.
; Server: Premium, FTMO, BlackBull, MetaQuotes
server = Premium
To use data from your broker, do the following:
- Create a new directory under the Express Generator's "data" directory for your files.
- Download the data files with the script you use to export data for EA Studio and put the files in the created folder.
Call the Generator with the corresponding "server" parameter. Use the created directory name.
Let's say the new directory is "MyBroker".
Call Express Generator with:
node .\bin\gen.js --server MyBroker --symbol EURUSD --period M30 Re: Connect EG to my Historical Data

Re: Connect EG to my Historical Data
I am trying to run EG with historical data I downloaded from Trading.com using the Data Export app. I created a data folder called Trading under the "data" directory. I then used power shell to fetch the data. I get the following error:
When I change the data directory to Premium it works!

Re: Connect EG to my Historical Data
You can load only the data we collect on our data feed servers.
The currently available servers are:
- Premium: Data from DukasCopy with real spread. Their crypto and gold data have unusual digit counts.
- FTMO - we will probably remove it because they no longer support algotrading.
- BlackBull - MT5 live account. Real spread. The data are shorter than those of the other servers. However, they have good BTCUSD, ETHUSD and Gold data.
- MetaQuotes - this is the default data feed for MetaTrader when you download it from the Metaquotes. Real spread.
We will explore the Trading.com data from their MetaTrader 5 and decide if they are good enough.

Hi Popov,
In a previous post above you stated the following:

- Create a new directory under the Express Generator's "data" directory for your files.
- Download the data files with the script you use to export data for EA Studio and put the files in the created folder.

Call Express Generator with:
node .\bin\gen.js --server MyBroker --symbol EURUSD --period M30
Is this no longer available to do?

Yes, of course. This is the way to use custom data.
The files will also contain spreads if you export data from MetaTrader 5.
Make a folder "Trading" under the "data" folder and use the generator as follows:
// MacOS, Linux
node ./bin/gen.js --server Trading --symbol EURUSD --period M30 ...
// Windows
node .\bin\gen.js --server Trading --symbol EURUSD --period M30 ...You don't need "fetch" when you use your data files.
If your data file is in another place, you can directly access it through its entire path.
node ./bin/gen.js --data-file /my-data-dir/data/Trading/EURUSD_M30.json ...
