Think about this, before you sign up to a trading academy or join a forex trading signal group, you usually would do a research about the trader or academy by observing them through checking their Youtube pages, Instagram accounts, Trustpilot, telegram channels, reviews from their clients, chatting with their support team, visiting their physical office and getting other relevant information about them.
This also applies to other products or services you buy, right?. The reason you do this is so that you can check if it is worth your time and money. This product research you do is what is known as BACKTESTING in the Forex market.
When you come to the Forex market, before you put your hard earned money on the line, it is important you do a research through backtesting.
Some traders may decide not to backtest but they may choose to test their trading strategy in the live market in a forward moving pattern. And while they do so, they observe and record the outcome.
It is however, still very much advisable to do a thorough backtesting of your trading strategy before trading it live.
To backtest effectively, you need a solid trading strategy. 
There are different approaches to trading the market. A writer once said that there are many ways to kill a rat. So it is in the forex market.
You can learn a trading strategy by checking through the course for different trading styles (both retail and smart money concepts) or you could develop your own trading strategy from the markets.
You cannot be trading without knowing if your trading style is profitable or not. It’s just like going to the war front without knowing the right weapon to go with because you have not taken the time to test the weapons. Your opponent will most likely ruin you. Even if you have the right weapons, you still need to test it, that way, you understand how it works and you can effectively use it and become more skillful in its application.
Backtesting is important for 2 main reasons.
1. You need to know whether your trading strategy has got an edge in the marktets. Your strategy should be able to tell you if it is profitable or not.
If it was profitable in the past, it is more likely to continue being profitable until otherwise proven. If it has a poor success rate then you will need to do away with it.
Let me ask you a simple question? What is the win rate of the strategy you are currently trading? Please drop your answer in the comment section.
If you’re trading with no idea of what your strategy win rate is, then you are going in the wrong direction and you need to retrace your footsteps before things get worse. 
2. You need to know how your strategy performs in different market phases/seasons. Good knowledge about the metrics of your strategy (winning trades, losing trades,drawdown, profit factor, and other important pointers) is a determinant factor in getting to measure the performance of your strategy.
