A good strategy in trading will help us avoid losses. Don't forget to upgrade your strategy so you can follow the market movements. a tradter should be able to determine for himself what to do whether it's a strategy or a moment to be able to avoid losses. for people who are still beginners, it would be better if you use a small capital first while learning to understand the market. do not be careless and in a hurry in trading because most people fail in trading because they are too hasty and not careful. do the best in trading as best we can and avoid the losses.
But even how good a strategy is, it will reach a certain time that its no longer effective so you have to level up your srategy or even build a new one that you think will definitely work and suit on you. And also, keep updated on the market trends and sentiments so you will know when is the best time to trade or not. As long as you don't lose most often like three times or more often than that, then your strategy is still worth using.
You are right. There is no stopping from learning in trading and level up your strategy because trading alone always depend much based on the current events and trends. And when the market becomes more unstable, it will be hard to trade and end up successfully. And it will help you from comitting losses if you have other backed up strategies that will still work on you when one strategy is already failing. I guess having losses more than three or four times is already unacceptable.
