(我不需要知道你實際的系統,只要評估你可能的最大槓桿就能得出這個結論, 如果你有避險或真的是當沖系統應該就沒差,除非交易所掛掉 XD) 我以前也有一陣子很熱衷跑回測,發現一個很有趣的現象,就是測試區間拉長時, 在某些值績效會差很大,看逐筆交易就會發現績效特別好的參數, 碰上系統性風險都剛好做對邊...背後的意義大家可以思考一下 最後轉篇Ed Seykota的文: System Trade Hi Ed! Today I bought 4 contracts of Cocoa. Entry 890. SL 772. Total Risk: 472 {4*(890-772)} Euro. My system is now up and running. When my SL-risk decreases I will put on new trades so my total SL-risk always is between 40-50% of my total equity. Can you suggest how to test this system more careful. I'm not sure that my money management is optimal. == Hmmm ... you are risking 40-50% of your Equity on one trade. Professional trend traders typically risk around one percent as much as you risk. You can test your system a couple ways. 1. You can back-test it on a computer and notice it goes broke on small whipsaws. 2. You can run it in real-time, as you are doing. When you go broke, your test is complete. -- FB: http://0rz.tw/l3Kcq █◣ ▊ ◥\◣◣\◣▼▼◣◣█◣ ▌ ╬╬ █銀ˊ どんだけ── ◥█◣ )) ▲▲██▲╴▲██▲ ▲ ▌ "囧█ ╬╬ █ˊ魂 好文要推── ◥█◣ ◢ ▏ ▼██▼ ▼██▼▏███▌m@▼▄ ╬╬ EVERYBODY SAY ◥█◣█ ▼█▇▇█‥ ▇▇█▏◣ ▌ ▲◇" ╬╬ 市場求生手冊─ (( ╲ ╲ ◣▼ ▇▇▇ ▼ ◣ ▌▆▆▆ ╬╬ http://stasistw.blogspot.com/╲█╲█ ◥██████ ◤████▆▅▄▃▂▁ --
