Hi Essam Saed ,
Did you set up the "oanda-access-token" and "oanda-account-id" in the config.json file?
I am using the latest version of Lean and have just created a new token and account. It looks like:
"environment": "live-oanda", // oanda configuration "oanda-environment": "Practice", "oanda-access-token": "96bad561d7e08bbae140aee21b3c5902-d4793375813acb3bthispartissecret", "oanda-account-id": "101-004-13727058-001",Essam Saed
Hi Alexandre Catarino
Thanks for your reply, actually i have adjusted this data, but my problem was arising from running lean on debug mode, later i figured out that i should run it in release mode, which made it work perfectly.
Thanks

Hi Essam Saed ,
You should be able to run Lean in both Release and Debug modes.
