I have been in the world of trading for a while, and over the years there have always been controversies over the best, whether to use a single strategy for trading or a combination of strategies.
Trading strategies are constantly changing so the probability of success in trading by applying a specific strategy is very low. Since this is an uncertain platform, nothing can be expected to be the same. However, the trading strategy can be changed or kept unchanged depending on the market conditions. If a trader is profiting by applying his strategy then he will undoubtedly try to apply that strategy according to the market situation. I think a strategy can be modified for different market conditions.
