Risk warning: CFDs and spread bets are complex instruments and come with a high risk of losing money rapidly due to leverage. You can lose money on these products, and each provider publishes its own loss figure under FCA rules. You should consider whether you understand how they work and whether you can afford to take the high risk of losing your money. Automated and API trading can amplify losses through bugs, connectivity failures and runaway orders.

## Sample

It holds no credential and needs none: the program runs inside a terminal that is already logged in to an account. Nothing is entered on this site.

```mql4
void OnStart()
  {
   PrintFormat("balance %.2f, equity %.2f, free margin %.2f",AccountBalance(),AccountEquity(),AccountFreeMargin());
  }
