Profit can also be taken via stop orders.
It climbs as predicted after establishing a buy trade at 105 yen and becomes 106 yen. There are 1 yen gains that have not been realized. I believe it will continue to increase, but if it does fall as a consequence of some major news, I want to make sure it does not result in a loss reduction.
In this situation, if you set a stop order at a rate higher than the opening price of 105 yen, for example, 105.50 yen, you may make a profit of roughly 50 sen even if the price falls and the order is executed.
When the market goes in the direction you anticipated and your unrealized profit grows, you can gradually increase the indicated rate of stop orders to maximize profit.
