A strategy can look profitable before trading costs are counted. But real performance has to include the cost of trading. That means looking at things like: • Trading fees • Funding payments • Slippage • Spread • Execution quality In Testnet, some of these costs may not behave exactly like Mainnet. So even if the strategy looks good now, I won’t treat the result as final real-money performance. The cleaner question is: After costs are included, does the strategy still have an edge? 這也是為什麼 Testnet 成績不能直接等同 Mainnet。 真正上線後， 手續費、Funding、滑價與成交品質， 都要一起算進去。 https://sasadaily.com/dsj?lang=en

A profitable-looking account doesn’t mean every gain is locked in. During the DSJ public test, I separate: • Realized PnL — profit or loss from closed trades • Unrealized PnL — profit or loss still moving with open positions Why does this matter? Because unrealized gains can disappear before a position is closed. So I don’t want to judge DSJ by one big equity number alone. What matters is how much performance is actually realized — and how much risk is still open. 帳面上的獲利，不等於已經真正落袋。 公開實測除了看 Equity， 也要分清楚已實現與未實現損益。 https://sasadaily.com/dsj?lang=en

A new high is exciting. But what matters more is what happens after a drawdown. During the DSJ 90-day public test, I’m watching: • How deep the drawdown gets • How long recovery takes • Whether recovery comes from steady trading or one lucky trade • Whether risk increases just to win losses back A strategy isn’t proven by how high it can climb. It’s proven by how it behaves when things go wrong. 創新高很好看。 但真正值得觀察的， 是回撤發生後能不能穩定恢復。 這也是 90 天公開實測要留下的紀錄。 https://sasadaily.com/dsj?lang=en
