Arbitrage is not really afraid of missing out once or twice; the real killer is making a few small trades in succession just skimming the surface, or suddenly hitting an unexpected market move. When your mindset collapses, you start making reckless moves, and that's when losses become true losses.

I added a stabilizer to my trading strategy called the "Profit Sedimentation Method." It sounds fancy, but it's actually a small trick for managing your mindset.

The execution rules are very strict: every Sunday night, I must do a full account reconciliation. Regardless of whether I made a profit or a loss that week, I forcibly withdraw 2% from my active arbitrage principal and transfer it into a stablecoin investment pool, as if that money has already been spent and is gone for good.

What's the benefit of doing this? When you're making a lot of money, 2% doesn't hurt or feel significant; you hardly notice it. But when profits are small or you're at a loss, that 2% becomes a signal to forcibly reduce your position, helping you lower your exposure and risk. More importantly, it fundamentally forces you to "take profits"—cash out when you’re ahead, and proactively shrink your position when things aren’t going well, preventing a single loss from snowballing.

Over time, that stablecoin account becomes like a water reservoir, with the water level gradually rising. Even if this month’s arbitrage opportunities are poor and I haven't made many trades, seeing the interest keep rolling in on the investment side makes me feel calm. You realize your foundation is getting stronger, and this sense of stability makes you especially calm when seeking opportunities and making decisions—knowing when to act and when to hold back.

This "insurance" actually provides peace of mind. When your mindset is stable, you won't gamble on ambiguous market conditions, and you'll find it easier to wait for and seize real big opportunities.
