Some friends are absolutely right—if there are losses during this liquidity crisis, instead of just blaming external factors, the key is to improve your own trading system. We immediately summarized a few of the simplest methods at the time and shared them with everyone. The principles are straightforward—keep them in mind, and you’ll achieve alignment between knowledge and action. 1. Always set a stop-loss, no matter what. 2. When a liquidity crisis occurs, your first reaction should be to check for arbitrage opportunities—this is just as important as bottom-fishing. 3. If the cause is human factors, be bold enough to buy during sideways movement, but don’t use leverage. There’s a high probability it will recover.
