The most important factor in determining a good profit target in forex trading is to have a realistic and achievable goal. This means that the profit target should be based on the amount of money that you are willing to risk in the trade, and the amount of time that you have available to devote to trading. It is also important to consider the risk/reward ratio of the trade, as well as the potential for unexpected losses or gains. A good profit target should also take into account the current market conditions, such as the volatility of the currency pair and the trend of the market. Finally, it is important to use technical analysis to determine a good entry and exit points for the trade.
