Backtesting is a crucial tool for me, as it provides valuable data on the potential performance of my strategies before applying them in real markets. It allows me not only to optimize my strategies but also to manage risks and increase my confidence in my trading decisions.
I recommend doing backtesting at least twice a week, even if you are profitable; it is a very powerful tool.
Some traders say that backtesting helps them to test their trading strategies and see how they perform in the market, and it shows them positive results. But there are also traders who do not really consider doing backtesting, because they see that the market is dynamic and we cannot rely on past market data for the future. So it depends on the trader how they see this backtesting, if they see that backtesting is important enough, they can practice it, if the results are positive they can use it for their trading - or if they feel it is not important then they can ignore it. But please note that backtesting is a trading method, and no trading method guarantees trading success.
