MQL4 MarketInfo()
Returns one item of data about a symbol in the Market Watch window, chosen by a request identifier: a price, or a dealing property such as the stop level.
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.
