 There are some adjustments that need to be made to MetaTrader Query Language
scripts (Expert Advisors) due to differences between Generic MetaTrader 4 and MBT
MetaTrader 4. These include, but are not limited to:


1) Scripts that use Instant Executions to place market orders with take profit
and/or stop losses attached will not work. Instead, a market execution must
be placed and then a take profit and/or stop loss added to the position.
2) Hard coding of +/‐ calculation of pips for profits may need to be adjusted to
reflect the fifth decimal place of our ECN.


 Generic MetaTrader 4 platforms typically quote forex pairs in pips, which means 4
decimal places on most pairs and 2 on JPY‐based pairs. MBT MetaTrader 4 quotes pairs
to the tenth of a pip, which adds a decimal place. Trailing Stops in MetaTrader 4 are
measured in “points,” not pips. Thus a 15 point trailing stop on Generic MetaTrader 4
must be entered as a 150 point trailing stop on MBT MetaTrader 4 to get the same 15
pip trailing stop results.


 Generic MetaTrader has internal customer account statements. However, to correctly
resolve the recent NFA rules regarding FIFO statements for customers, all MetaTrader
statements have been turned off. Customers can get accurate FIFO‐compliant
statements via the MB Trading website login, just like a Navigator account. In addition,
customers can log into Navigator and view their MetaTrader account balances, orders,
and positions.


 Generic MetaTrader handles only up to 5 decimal places (3 on JPY‐based pairs). This is a
recent event, as only 4 decimals were supported previously. However, on an ECN,
partial fills for market order entries can occur, causing average prices that result in
more than 5‐decimal pricing. This can mess up EAs and cause positions not to be
closable. Therefore, MBT MetaTrader 4 will round to the fifth decimal place (3 on JPYbased
pairs) any ticket that gets a multi‐part fill that results in an average price that
goes beyond that fifth decimal. This will not be rounded on customer statements, which
are handled through Navigator and do not round pricing. Therefore, on the rare
occasions where this occurs, the balance showing in the customer account in
MetaTrader could be off by a small amount, usually pennies based on trade size,
following that trade due to the rounding. If this occurs, then on the next day where the
account is flat all positions at 5 pm EST rollover, a credit or debit for this amount will
occur shortly thereafter to balance the account.

如果没有看错,应该是ECN交易商MBT提供的mt4软件与普通的mt4之间的差别。


还有一些需要作出调整MetaTrader的查询语言
脚本(专家顾问)由于MT4客户之间的通用和MBT分歧
MetaTrader的4。这些包括但不限于:


1)脚本,使用即时处决,便可采取利润市场秩序
和/或附加不会停止工作的损失。相反,市场必须执行
放置,然后一个以利润和/或停止亏损增加的立场。
2)硬盘的+ / -的利润点计算编码可能需要进行调整,以
反映了我们茄第五个小数位。


通用平台MT4客户通常报价点子外汇对,这意味着4
在大多数对和2对日元的对,小数位。主战坦克4 MetaTrader的报价对
以一个点子,增加了一个小数位的十分之一。尾随在MetaTrader的4站是
衡量“点”,而不是点。因此,一个15点落后于通用MetaTrader的4站
必须输入一个150结尾的主战坦克MetaTrader的4站,以获得相同的15
点子的跟踪止损的结果。


通用MetaTrader的有内部客户帐户报表。但是,正确
解决最近NFA的规则,先进先出报表的客户,所有进入MetaTrader
报表已经关闭。客户可以得到准确的FIFO兼容
通过MB的交易网站登录发言,就像导航帐户。此外,
客户可以登录到导航,查看他们的MetaTrader的账户余额,命令,
和立场。


通用MetaTrader的处理只到5个小数位(3日元的对)。这是一个
最近发生的事件,因为只有4位小数了支持以前。然而,在一个电子,
部分填补了市场秩序,作品可以发生,导致这一结果的平均价格在
超过5十进制定价。这可以搞乱定的环境,并导致职位不被
可关闭。因此,主战坦克将MetaTrader的4轮第五小数位(3月JPYbased
对)任何票证得到一个多部分填补这个结果平均价格
超出的五分之一小数。这会不会凑客户的陈述,这些
通过导航处理,不全面的价格。因此,在罕见
一些情况下,发生这种情况,余额显示在客户的帐户
MetaTrader的可能是关闭的一小部分,通常是基于贸易规模便士,
下面,贸易,由于四舍五入。如果发生这种情况,然后在第二天当
帐户持平于下午5点过渡,信用卡或借记这笔款项将全部职位
此后不久发生的一本帐。
