1-5a. Open a position

 The first thing you need to do in Forex trading is to open a "position". A position is a market term that refers to the amount of money you have built in a new transaction. It is not limited to Forex, but in investment, it is basic to open a position and settle the position by counter-trading to fix the final profit and loss.

 Suppose that you bought the US dollar / yen when 1 US dollar = 100 yen, predicting that the US dollar / yen rate (price) will rise in the future. This is the state where you have a US dollar / yen buy position at 100 yen. By finally selling and closing this position at some point, the transaction is completed, and the profit and loss is fixed.
