Market Order

Market Order - An order to buy or sell a currency pair immediately at the best available price. Market orders execute instantly against the current bid or ask quote, so the trader accepts the prevailing price. For example, in a Forex robot one might call a function like PlaceMarketOrder(TradeType.Buy, Symbol, volume) (cTrader Automate API) or use OrderSend() in MetaTrader to submit a market order. Market orders ensure execution but give no control over the exact fill price, so they are used when immediacy is more important than price.
