Trading is an amplifier of emotions, and you will be scared by your own weaknesses
The panic of sudden plummeting
The all-in heavy positions
The difficulty of trading
Is precisely because we are human, and as humans, we have emotions
Emotions significantly affect us in trading, but emotions are also the source of creativity
Some say that truly excellent traders are emotionless, but I think that's not entirely true
Excellent traders have the ability to combat emotions, a mechanism to self-manage under emotions
This is also part of the trading system
Every trader knows that good trading requires a system
But most people cannot tolerate a system that incurs losses
When losses occur, they keep modifying the reference, until eventually even the key parts that were once profitable are modified
Then the trading curve will gradually decline in an unstable spiral
Even the legendary hedge fund manager Simons has said, "If you don't have a long enough time to follow your system, let it work and profit, then no trading system will work"
You must know that this old man is a money-printing machine on Wall Street, a person who solved trading with mathematics
Speaking of this old man, his Medallion Fund's return rate is almost unmatched, and it's based on continuously evolving quantitative models
Such a system is akin to being emotionless, but the downside is that it cannot manage large funds, as this kind of cheat-like arbitrage has limited capacity in the market
Therefore, a truly successful system needs to be consistently operated, it needs to be allowed to fail, the key lies in executing with iron discipline after a failure
Only with a sufficiently long history backtest can one discern the patterns that arise
Finding your trading advantage in historical searches, maintaining the advantages, while the disadvantages must be dealt with disciplined responses
In the end, a good system is definitely not the one with the highest win rate
What determines profitability is the magnitude and frequency of losses and wins, not just the win rate
The key is whether you can consistently and sustainably operate your trading system
All emotional consequences leading to serious outcomes are also due to the lack of a strictly enforced system
