已添加主题你们的电脑是怎么登陆MQL社区的?DNS是怎么设置的?我公司可以登录,在家无法登陆。
如题。一开始也有人问过这个问题,当时我把公司电脑的dns改成了114的,可以登录论坛了。但是,我家里的电脑,dns114或者8888都不行。家和公司在一个城市,就是无法访问社区。 还有就是,在公司里,我用安卓手机无法登陆论坛,即使安卓上把DNS修改了也不行。 目前,能登陆的只有公司的电脑了。你们是怎么解决的?

已添加主题有人研究过在MQL5语言上怎么求解最优化问题?
比如: out = f(x)  根据x的值域,得出使得out最大的x值。 out = f(x, y) 根据x的值域、y的值域,得出使得out最大的(x,y)的值。 ... 函数f 非常复杂,不可能通过数学求解。只有通过暴力测试或者最优化求解。  但有有人知道怎么在MQL5上实现最优化运算吗?ALGLIB 库似乎可以,但是我没有研究过,有用过的能给个案例吗?

已添加主题MT5的回测能否通过程序来控制?
在回测时MT5的是通过鼠标和键盘。 当我想对许多模式进行回测时,每次都必须这样做,这很麻烦。 例如: mode_1:我要测试参数A,B。 mode_2:我要测试参数C,D。 mode_3:我要测试参数E,F。 ... 有没有一种方法可以在没有手动控制的情况下自动完成每种模式的回测? 但是也不能把各个模式写到一个策略里,那样会面临参数爆炸。 我看到官方文档说可以用命令行的形式来启动,但是加载的参数范围需要  sample.set,这个 set 文件 怎么设置的?

已添加主题你们用mt5回测时,点差可以设置吗?
我设置了回测的品种属性,但是点差始终是50,而且是浮动的。我想固定在某个值,但是我发现固定的值仅仅是限定最小点差而已,点差依然是浮动的。

已添加主题你们在python上技术指标库用的是什么?怎么解决与MT4/5指标算法不一样的问题,是重写吗?
如题。我用的是talib。但是很多同名指标算法与MT5上的是不一样。你们后来是自己重写的,还是怎么解决的?

1. Development background Forex is a ratio, different from futures and the stocks. For example, if EURUSD has risen, it may be that EUR is falling and USDX has fallen even more.  I believe everyone knows that the US dollar index is an essential reference index in forex analysis .  In MT5 client, it is very valuable to see the US dollar index. Similarly, if you can see the index of other forex in the MT5 client,  which is very valuable for trading.  Because the US dollar

1. Why did I develop this series of indicators I found that most traders need to use multiple time frame indicators. They usually switch time frame to see indicators. However, once the timeframe is switched, you cannot see the  corresponding relationship  between  the price in the smaller timeframe  and  the indicator in the larger timeframe . For example: if your price chart is in H1 timeframe, you can see H4, D1 and W1 indicators in H1 timeframe Chart. This is more
