我仍清晰地記得2008年的“保證金大追加”，我也記得金融危機期間，每天醒來都會看到CNBC屏幕上血紅的數字。
我還記得巴菲特說過，我們已經離開ATM機24個小時了，再也取不出錢了。那是可怕的、讓人著迷的一段時間。
那時我還是一個交易員，但是我沒有進行交易。那時候我忙著調查，忙得筋疲力盡。但實際情況是，我和其他人一樣害怕，但卻很慶幸沒被套在市場裡。自始至終，我都沒有準備好。
將時間推至上週五（2015年8月21日）到今天這段時間。
同2008年8月的水平相比，這算不上危機，但確實讓人緊張。道瓊斯指數的下降幅度多年未見，各大網站都將市場新聞移至首頁。
而此時此刻，我在市場中，有一個測試了12年的機器人。
機器人不會神出鬼沒，它會在混亂的市場中不斷交易。這是件好事嗎？機器人在這場危機中表現如何？
在這裡澄清一下，我用四個不同的機器人交易四個不同的賬戶。即使在我休假的時候也不會關掉機器人，因為我從來不會關掉他們，除非我收到了緊急信號或是危險的警告。簡而言之，我今年只關掉機器人一次，就是收到極度危險信號的時候。
當然，不是每個機器人或交易系統都能攻克危機，但是你若能找到合適的系統，降低虧損的風險，增加盈利的因素，你就會擁有更好的機會。
底線就是：如果你的系統完美地通過了測試，你就能抵禦市場暴跌。如果你不確定，就可以回頭看看2008年8月-12月，看看你的系統在那時候表現如何。可能你的系統表現得並不完美，但它能夠撐住你，你就可以趁此機會撤出。
風險很可怕，你可能被吓跑，也可能慌了手腳胡亂交易。但是機器人不會害怕，他們只是一筆接一筆地交易，這在市場暴跌時事件好事。
Can Robots Navigate You Through a Crisis?
Robots don’t get spooked and robots have reasons to keep on trading right through the mess. So, is that a good thing?
I vividly remember The Great Margin Call of 2008. I also remember waking up each day during that financial crisis and watching the bloody red numbers racing across the CNBC screen.
Finally, I remember Warren Buffett saying that we were all about twenty-four hours away from going to our ATMs and having no money come out. It was a horrifying, mesmerizing time.
I was a trader at the time, but I wasn’t trading. I was deep into research at the time, and I won’t put anything in the market until I’ve tested it exhaustively. But the truth was: I was scared just like everyone else. Every day during the crisis I was happy that I wasn’t in the market. All along, I simply wasn’t ready.
Fast-forward to last Friday (August 21, 2015) and all the days up until today.
While I wouldn’t call it a crisis on the level of August, 2008, I would still say it’s been pretty intense. The Dow has been dropping in quantities not seen in years and newspaper articles about the markets have moved to the front pages. Hundreds of billions of dollars have been lost in a matter of days.
This time around, however, I am in the market. This time around, I have robots that have been tested over 12 years of data.
Robots don’t get spooked and robots have reasons to keep on trading right through the mess. So, is that a good thing? How have the robots done during this crisis?
For clarification, I trade four different robots in separate accounts (the same ones I’ve traded for several months). I did not turn any of them off while I was on vacation and because I don’t turn robots off at all, unless I get an emergency notice from Tradestation or something dire along those lines. In short, I’ve turned my robots off exactly once this year due to any sort of potentially calamitous development.
Of course, not every robot or trading system does well in a crisis. But, if you choose a system with a good profit to drawdown ratio and a good Profit Factor, your chances get much better.
The bottom line is: If your system has been thoroughly tested, you should be able to weather a market meltdown. If you’re not sure, you can always go back to August-December of 2008 and see how your current system would’ve done. Your system probably won’t be perfect during that time, but it should hold up enough so that you could take every trade and come out okay on the other side.
Crises are scary and it’s easy to be scared out of the market or scared into trading your system improperly. But robots are never scared. They just go on to the next trade. And that’s a good trait to have during a meltdown.
