MQL4 OrderClose()
Closes an open order, in full or for a given number of lots, at a price you pass.
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.
This is an MQL4 function, not an HTTP endpoint. It has no method, no path and no address to send a request to: it runs inside the MetaTrader 4 terminal, in a program written in MQL4.
In MetaTrader 4 an open trade is itself called an order, so this is the call that closes what other platforms call a position.
