Buy or Sell

For the concept of profit if the price rises may not need to explain because it is a reasonable concept, we buy something when it's cheap (Open Buy) and hope the price goes up then sell them (Sell Liquid), profits can be the difference in price with the purchase price.

So what if the price drops? How to get the benefit?

Background Market Forex Market is very large, the international market worldwide
and transactions happen quickly.

Concept to profit when the price falls are:

AT FIRST SELL EXPENSIVE PRICE
THEN
BUY BACK PRICE DOWN TIME.

How can I sell if I have not bought?

Could, because there are people who want to lend it to you!

A simple example is the system in the world Trade Consignment, which we loaned by the supplier of goods to be sold and we do not directly pay for the goods we receive. After the goods are sold to our customers (of course more expensive than the purchase price to the supplier), then we pay it back at our supplier with a cheaper price than the selling price to our customers.

Well so did the Forex Trading, when you open a Sell position, then you borrow another person's position to be sold and you should return the market to buy from again, certainly the hope when we get to repay the loans, are cheaper (down) than when we sell / borrow (Sell).

This process is performed by the system through the stock, so we do not know from whom we borrow / sell open positions and from whom we buy / Sell position is closed plus the worldwide Forex Market so there's always those who sell or buy at the time.

Well this is the concept of Open Sell, Sell open position (sell) and expect the price falls so that we can close (Buy Liquid) with a lower price. Benefits derived from the difference in price with the purchase price. But if prices rise above the purchase price (Open Buy), then you lose
