Solidifying trading rules is just to ensure that opening and closing positions are orderly and not blind; as for right or wrong, that is left to the market for validation. This is not called being obsessed. A trader without any trading rules finds it hard to survive in the trading market.
You can take a look at the delivery orders*; if usually, small profits accumulate, but one or two trades wipe out most or all of the profits, you might want to ask if there are any trading rules or if those rules are being adhered to.
Whether it's fundamentals or technicals, there is a comparison. The push from fundamentals will be manifested in the K-line; how do you judge the direction to open a position with such a chaotic K-line? How do you set your stop-loss position? You might as well flip a coin, where heads or tails represent a direction, but you need to decide in advance, right? So it’s not about being obsessed with trading systems; it’s simply about trying to optimize multiple times to secure better entry and exit positions.
Even if you adhere to trading rules, you cannot completely eliminate market risk; extreme market conditions, sudden changes in liquidity, etc., may still breach preset boundaries.
Do your trading rules help filter out noise, or are they easily abandoned amid fluctuations?
