In trading, stop-loss is the core principle concerning survival and profitability. The ancient saying 'A small tolerance leads to the disruption of a grand strategy' is particularly applicable here — when facing small floating losses, if one blindly allows them to continue without timely stop-loss, it may seem that 'small losses' have been temporarily avoided, but in reality, it can infinitely amplify risk, ultimately evolving into irretrievable massive losses. When losses expand to a certain extent, traders often fall into psychological dilemmas: either missing the best handling opportunity due to hesitation or making irrational moves out of panic, thereby missing more potential opportunities.

In summary:

1. A reasonable stop-loss is a 'cost' that must be incurred in trading. Just as running a business requires initial investment, if one is unwilling to bear even the necessary stop-loss cost in trading while trying to completely avoid risk, it will instead lead to a loss of the foundation for profitability due to uncontrolled risk.

2. There is no unified standard for setting stop-loss levels; it must be judged comprehensively based on personal risk tolerance, the rationality of entry points, and expected risk-reward ratios. For example:

For a conservative account, the maximum floating loss per transaction is set at 10%~15% as the stop-loss line. This range can filter out short-term fluctuations within a controllable scope while avoiding the psychological trap of 'not wanting to cut losses' as losses expand, thus preventing operation from going out of control or even liquidation.

For an aggressive small account used for 'small bets for big gains', the stop-loss can be relaxed to 50% or even set at the liquidation threshold. However, the prerequisite is that the total capital of the small account must be set within the range of 'even if all is lost, it will not cause a significant psychological burden', to align with its high-risk, high-volatility positioning.

It is particularly important to note that the logic of account operation should not be confused — one cannot apply the aggressive stop-loss thinking of a small account to operate a conservative account, as this would undermine the risk control system of the conservative account, and vice versa. Only by matching the stop-loss strategy with the account positioning can a balance between risk and reward be found.
