我想知道历史数据测试和实际交易的结果会有多大的不同，是变好了还还是变坏了？

People doing real trading won't paper trade.
People paper trade can't tell you result from real trading.

So, what are you expecting?

对谁／对哪个公司而言？

他们是用数学算法从数字变化中找规律。跟投资毫无关系。

是啊。炒股票，股票进进出出，跳楼的跳桥的都有，怎么统计。

I have use strategy tester in forex automated trading, why?

Don't believe in that thing cause too many variances, emergency, implusive decision by trader...

货币交易价格是全球统一的，不同的公司只是点差有点区别而已。

That "只是点差有点区别" is the key.

For example, spread 0.1 and 0.2 seems small, but that could kill the account, not filling in the trade and many other things.

没人能回答这个问题。如果能知道变好了，就继续，如果能知道变坏了，反着做。能知道答案的早就全球首富了。

paper trade for fun, real money trade for money. I do both. I paper trade what I shouldn't do with my real money. My paper trade return twice as much as my real money. even I only place paper trade orders blindly when market is closed once in a while. but i never apply my paper trade to real. such as short twtr @64, bbry @10, amzn @404. buy 200 td call options.

I guess he is asking, for the same strategy, will there be any difference between paper and real trading.

Since you are having 2 strategies, one on paper and one for real. So this doesn't answer his concern.

你这人蛮高级的嘛

我听出来了，你骂我

其实我就是XMDJH

 

[uglyducking]

终于有人明白我的意思了

这都100多楼了，你真不容易

对于这些投资大V们我也终于知道他们都在忙活啥了

他们都是傻瓜。

投资领域并不存在什么高级低级，但有投资经验的人不以最求最高收益来判断投资的好坏，而是以风险控制和受益率的平衡来评估投资的质量。能够创造长期稳定而且超过某一个或几个benchmark的，一般可以确定为好的投资。但实施起来很难判断，因为会此一时，彼一时。

我觉得股票这个东西一年翻几倍都不稀奇。
难得的是能坚持多久。很多人年年翻翻，遇到一次毁灭打击全赔进去的太多了。。。

 

[uglyducking]

投资领域存在高级低级区别，回报率高的就是高级的。投资不同的领域就如同人选择职业，不同的职业工资水平相差很大。投资成功与否的评判标准很简单，只看利润水平。无论理论水平多高，赔钱了就是废物，蠢材。

永久的废物蠢材还是你能陶乐润特暂时的废物蠢材？巴菲特几年前很蠢很废是不是？
