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.
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?
Apart from in trading there is always need to have two instead of one.
1. One can obviously fail and you will need a backup
2. One does not provide alternatives.
When you have multiple strategies you will have to know where and when you will apply each one.
Apart from the above, a strategy fails at a time, so you will need a backup incase you main strategy works.
