Personally, I don't have issues with that, many of my trading strategies can stand alone. But experience chose for me over time. I now combine trading strategies and it has helped me to better filter my trading signals for greater performance. And if any of that strategies did not confirm the same signal, I do not go for it.
What about you, what is your preference, and why?
I will do a combination of every strategy that I run in trading and will see the accuracy of current market conditions so that if one way doesn't work then we have another chance to make a profit. Although under certain conditions some of the ways that we do are also frequent and will end in losses due to an incorrect level of prediction accuracy. But for day traders, the strategies they use are usually adjusted to market conditions, because basically everyone involved in trading is to make a profit.
But all this time I didn't know exactly what the combined strategy meant by many people, because when trading the strategies used are in accordance with the accuracy of the market and the intended combination, is it related to uptrends and downtrends? because what I understand is that scalping trades usually don't take long to last and swings actually have a much longer duration.
