以下是Satori指标的新版本（只增加了货币Currency1和Currency1的指数）。

开设了一个新账户，在MIG检查。开始使用该指标，然后把它从图表上拿下来，检查所创建的图表--没有一个错误（文件是空的）。现在我将检查MIG对GBPJPY H4、EURUSD H4、GBPUSD H4的报价档案（为了实验的纯粹性，我使用以前检查的货币）。

Forex Trader 2006.11.15 12:06 #43

我发现一个奇怪的现象，GBPJPY历史是空的（EURUSD H4和GBPUSD H4历史是到位的），可能是因为TestFile.csv和TestFile.csv2文件中缺少数据。同时，GBPJPY H4图表本身也显示正确。我已经怀疑
1）时间序列似乎被缓存了（这就是为什么图表显示）
2）数据中心地址（在终端通过数据中心连接到Alpari演示账户之前）

。所以我删除了数据中心地址并切换到Alpari演示账户，切换成功，数据中心被断开了。切换回MIG模拟账户--与服务器连接成功，但MarketWatch的数据没有变化。被迫更新GBPJPY H4（图表上），历史反弹。
但最后的报价时间仍然是所有对的10-43。我有一个建立199。

现在我将尝试运行Redraw2指标

，我看了看MarketWatch--到处都有相同的时间10：43。

Forex Trader 2006.11.15 12:32 #44

嗯...结果发现它是通过数据中心连接的。现在好了，MarketWatch显示的是正确的数据。现在试图了解更深的历史。

Forex Trader 2006.11.15 13:29 #45

更新，引文中有些地方非常有趣

Forex Trader 2006.11.15 14:17 #46

如果这个图是米格公司的，他们就有这样的招数。今年已经看过好几次了。我的欧元兑美元历史上有一个来自MIG的Dojic 08.09.2004的高点~1.7493。

Forex Trader 2006.11.15 14:24 #47

是的，它是米格的 :)

Forex Trader 2006.11.15 14:54 #48

为了以防万一，我在启动指标之前重新启动了终端（以避免时间序列的缓存）。在索引号1000之后又出现了错误。

现在，我将做第三个变体来点缀所有的点。

下面是第三个版本

第三个版本没有给出明确的答案，我们将不得不在每个工具的4小时时间框架上检查Time[]，看看是否有任何额外的秒数。如果没有找到秒针，那么就有一个终端错误。
