※ 引述《ChangJane (張卷)》之銘言:
: 我自己對於最佳化的看法是這樣的:
: 由於參數的變動導致對過去走勢的參與期間或程度有所改變 因此影響到績效
: 以通道突破為例 該取十天高點還是十五天高點還是二十天高點?
我重點會擺在一個邏輯現在會不會有用
而不是它長期下來是否有用 因此參數也不會是值得care的地方
或許你覺得長期下來可用就ok
但人生就像打保齡球
同樣都是3個strike 4個spare 3格沒解到
為什麼分數差那麼多 (你應該懂我的意思)
: 如此看來 不要突然失心瘋地加大部位 離掛點還有一段很長的距離
如果你賠錢
你即使不會賠到掛點 但是肯定浪費時間
錢再賺就有 時間生命則是一去不復返
如果你不知道何時加大部位 那你的規模很難 上一階
連續3個strike 最好是自己主動出擊
要等天上掉下來 不知要何年何月
