What do you do to a trading strategy that already earns you a good percentage in profit. do you still try improving on it to ensure it does not fail? or do you let it be until it starts showing signs of failure?
It is a simple question but I think answers and opinions will be different considering that some traders may fear further tampering with the strategy, others will no want to wait until it fails, what is your style?
We shouldn't just learn one strategy, but rather explore a variety of strategies. While learning too many strategies can be confusing in our trading, being able to manage them effectively will be better for us.
Learning a variety of strategies certainly makes us more flexible and able to adapt the strategies we learn to various market conditions. This allows us to potentially achieve greater profits because we can capitalize on various opportunities. If we rely on only one strategy when we experience a loss, we don't have other strategies to compensate.
This also answers your question: should we change strategies before experiencing a loss or after? The answer is that we should have several strategic references to be more flexible in trading and adapt to market developments. Granted, this may not always work, but it allows us to minimize losses.
