## Market Order

There are three types of orders that can be placed in MetaTrader: market, stop and limit orders. Being the most common, a market order opens a position immediately at the nearest Bid or Ask price.

### Buy

OrderSend(Symbol(),OP_BUY,0.1,Ask,2,Bid-15*Point,Bid+15*Point);

double bid   =MarketInfo("GBPUSD",MODE_BID); // Request for the value of Bid
   double ask   =MarketInfo("GBPUSD",MODE_ASK); // Request for the value of Ask
   double point =MarketInfo("GBPUSD",MODE_POINT);//Request for Point
   // Opening BUY
   OrderSend("GBPUSD",OP_BUY,0.1,ask,2,bid-15*Point,bid+15*Point);
   Alert (GetLastError());                      // Error message
   return;                                      // Exit start()
