使用MT5 API和Python进行交易

第一批关键功能之一就是以编程方式打开交易。既然您已经了解了如何打开与MT5的连接并提取数据。在今天的帖子中，我将向您展示如何使用MT5 API和Python进行交易。

验证仪器是否存在

让我们从上一篇文章的连接代码开始：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><span style="color:#c72c4c">import</span> MetaTrader5 <span style="color:#c72c4c">as</span> mt5

<span style="color:#c72c4c">else</span><span style="color:#5f5f5f">:</span><span style="color:#c72c4c">print</span><span style="color:#5f5f5f">(</span><span style="color:#407b08">"Failed to connect at account #{}, error code: {}"</span><span style="color:#5f5f5f">.</span><em><span style="color:#407b08">format</span></em><span style="color:#5f5f5f">(</span>account<span style="color:#5f5f5f">,</span> mt5<span style="color:#5f5f5f">.</span>last_error<span style="color:#5f5f5f">(</span><span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">)</span></code></span></span>

让我们通过建立一个使用帐号的名为connect的方法来进行清理：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><span style="color:#c72c4c">import</span> MetaTrader5 <span style="color:#c72c4c">as</span> mt5
<span style="color:#c72c4c">from</span> datetime <span style="color:#c72c4c">import</span> datetime<em><span style="color:#c72c4c">def</span></em> <span style="color:#0077aa">connect</span><span style="color:#5f5f5f">(</span>account<span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">:</span>account <span style="color:#c72c4c">=</span> <em><span style="color:#407b08">int</span></em><span style="color:#5f5f5f">(</span>account<span style="color:#5f5f5f">)</span>mt5<span style="color:#5f5f5f">.</span>initialize<span style="color:#5f5f5f">(</span><span style="color:#5f5f5f">)</span>authorized<span style="color:#c72c4c">=</span>mt5<span style="color:#5f5f5f">.</span>login<span style="color:#5f5f5f">(</span>account<span style="color:#5f5f5f">)</span><span style="color:#c72c4c">if</span> authorized<span style="color:#5f5f5f">:</span><span style="color:#c72c4c">print</span><span style="color:#5f5f5f">(</span><span style="color:#407b08">"Connected: Connecting to MT5 Client"</span><span style="color:#5f5f5f">)</span><span style="color:#c72c4c">else</span><span style="color:#5f5f5f">:</span><span style="color:#c72c4c">print</span><span style="color:#5f5f5f">(</span><span style="color:#407b08">"Failed to connect at account #{}, error code: {}"</span><span style="color:#5f5f5f">.</span><em><span style="color:#407b08">format</span></em><span style="color:#5f5f5f">(</span>account<span style="color:#5f5f5f">,</span> mt5<span style="color:#5f5f5f">.</span>last_error<span style="color:#5f5f5f">(</span><span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">)</span>
</code></span></span>

接下来，您将要创建另一个方法，并使用以下签名将其命名为open_position：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><em><span style="color:#c72c4c">def</span></em> <span style="color:#0077aa">openPosition</span><span style="color:#5f5f5f">(</span>pair<span style="color:#5f5f5f">,</span> order_type<span style="color:#5f5f5f">,</span> size<span style="color:#5f5f5f">,</span> tp_distance<span style="color:#c72c4c">=</span><span style="color:#990055">None</span><span style="color:#5f5f5f">,</span> stop_distance<span style="color:#c72c4c">=</span><span style="color:#990055">None</span><span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">:</span></code></span></span>

在开始交易之前，建议添加一些安全检查。这是要确保要执行其订单的工具存在并且可以与经纪人进行交易：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><em><span style="color:#c72c4c">def</span></em> <span style="color:#0077aa">open_position</span><span style="color:#5f5f5f">(</span>pair<span style="color:#5f5f5f">,</span> order_type<span style="color:#5f5f5f">,</span> size<span style="color:#5f5f5f">,</span> tp_distance<span style="color:#c72c4c">=</span><span style="color:#990055">None</span><span style="color:#5f5f5f">,</span> stop_distance<span style="color:#c72c4c">=</span><span style="color:#990055">None</span><span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">:</span>symbol_info <span style="color:#c72c4c">=</span> mt5<span style="color:#5f5f5f">.</span>symbol_info<span style="color:#5f5f5f">(</span>pair<span style="color:#5f5f5f">)</span><span style="color:#c72c4c">if</span> symbol_info <span style="color:#c72c4c">is</span> <span style="color:#990055">None</span><span style="color:#5f5f5f">:</span><span style="color:#c72c4c">print</span><span style="color:#5f5f5f">(</span>pair<span style="color:#5f5f5f">,</span> <span style="color:#407b08">"not found"</span><span style="color:#5f5f5f">)</span><span style="color:#c72c4c">return</span><span style="color:#c72c4c">if</span> <span style="color:#c72c4c">not</span> symbol_info<span style="color:#5f5f5f">.</span>visible<span style="color:#5f5f5f">:</span><span style="color:#c72c4c">print</span><span style="color:#5f5f5f">(</span>pair<span style="color:#5f5f5f">,</span> <span style="color:#407b08">"is not visible, trying to switch on"</span><span style="color:#5f5f5f">)</span><span style="color:#c72c4c">if</span> <span style="color:#c72c4c">not</span> mt5<span style="color:#5f5f5f">.</span>symbol_select<span style="color:#5f5f5f">(</span>pair<span style="color:#5f5f5f">,</span> <span style="color:#990055">True</span><span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">:</span><span style="color:#c72c4c">print</span><span style="color:#5f5f5f">(</span><span style="color:#407b08">"symbol_select({}}) failed, exit"</span><span style="color:#5f5f5f">,</span>pair<span style="color:#5f5f5f">)</span><span style="color:#c72c4c">return</span><span style="color:#c72c4c">print</span><span style="color:#5f5f5f">(</span>pair<span style="color:#5f5f5f">,</span> <span style="color:#407b08">"found!"</span><span style="color:#5f5f5f">)</span></code></span></span>

为确保此代码有效，让我们尝试连接并打开不存在的仪器上的位置：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><span style="color:#c72c4c">>></span><span style="color:#c72c4c">></span> connect<span style="color:#5f5f5f">(</span><span style="color:#990055">39672374</span><span style="color:#5f5f5f">)</span>
Connected<span style="color:#5f5f5f">:</span> Connecting to MT5 Client
<span style="color:#c72c4c">>></span><span style="color:#c72c4c">></span> open_position<span style="color:#5f5f5f">(</span><span style="color:#407b08">"Fake_Pair"</span><span style="color:#5f5f5f">,</span> <span style="color:#407b08">"BUY"</span><span style="color:#5f5f5f">,</span> <span style="color:#990055">1</span><span style="color:#5f5f5f">)</span>
Fake_Pair <span style="color:#c72c4c">not</span> found</code></span></span>

当我们使用参数“ Fake_Pair”调用open_position方法时，它未能按预期找到该对。

现在尝试使用有效的货币对，例如“ EURUSD”：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><span style="color:#c72c4c">>></span><span style="color:#c72c4c">></span> connect<span style="color:#5f5f5f">(</span><span style="color:#990055">39672374</span><span style="color:#5f5f5f">)</span>
Connected<span style="color:#5f5f5f">:</span> Connecting to MT5 Client
<span style="color:#c72c4c">>></span><span style="color:#c72c4c">></span> open_position<span style="color:#5f5f5f">(</span><span style="color:#407b08">"EURUSD"</span><span style="color:#5f5f5f">,</span> <span style="color:#407b08">"BUY"</span><span style="color:#5f5f5f">,</span> <span style="color:#990055">1.0</span><span style="color:#5f5f5f">)</span>
EURUSD found!</code></span></span>

您可以在上面看到这对货币对已经找到并且可以交易了。

执行订单

现在，我们准备使用带有Python的MT5 API进行交易。您需要做的第一件事是获取您正在交易的工具的“点”。该点定义为工具可能发生的最小价格变动幅度。

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python">point <span style="color:#c72c4c">=</span> symbol_info<span style="color:#5f5f5f">.</span>point
volume_step <span style="color:#c72c4c">=</span> symbol_info<span style="color:#5f5f5f">.</span>volume_step</code></span></span>

接下来，创建一个if语句来检查您的订单是买还是卖。这很重要，因为根据您是购买还是出售，止损和获利的计算方法有所不同。

方法签名中的止损和获利是距原始价格的点差。对于MT5，您需要提供止损并获利价格（如果您使用止损并获利–它们也可以留为空白）。要计算此值，您必须采用当前价格，然后将止损/获利乘以点，再加上或减去。下面是一个示例：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><span style="color:#c72c4c">if</span><span style="color:#5f5f5f">(</span>order_type <span style="color:#c72c4c">==</span> <span style="color:#407b08">"BUY"</span><span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">:</span>order <span style="color:#c72c4c">=</span> mt5<span style="color:#5f5f5f">.</span>ORDER_TYPE_BUYprice <span style="color:#c72c4c">=</span> mt5<span style="color:#5f5f5f">.</span>symbol_info_tick<span style="color:#5f5f5f">(</span>pair<span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">.</span>ask<span style="color:#c72c4c">if</span><span style="color:#5f5f5f">(</span>stop_distance<span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">:</span>sl <span style="color:#c72c4c">=</span> price <span style="color:#c72c4c">-</span> <span style="color:#5f5f5f">(</span>stop_distance <span style="color:#c72c4c">*</span> point<span style="color:#5f5f5f">)</span><span style="color:#c72c4c">if</span><span style="color:#5f5f5f">(</span>tp_distance<span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">:</span>tp <span style="color:#c72c4c">=</span> price <span style="color:#c72c4c">+</span> <span style="color:#5f5f5f">(</span>tp_distance <span style="color:#c72c4c">*</span> point<span style="color:#5f5f5f">)</span>

现在，该调用实际提交订单的API了。为此，我们将使用MT5 API中的order_send（）方法。但是首先，让我们建立我们的请求。可以在此处找到MT5 API可用方法的完整列表。

该请求是具有以下键的字典：

行动
符号
卷
类型
价钱
魔法
评论
type_time
类型填充

如果您想知道神秘的参数“ magic”是什么意思，它实际上只是一个客户ID（可以设置为任何数字）。在我们的例子中，请求的编码如下：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python">request <span style="color:#c72c4c">=</span> <span style="color:#5f5f5f">{</span><span style="color:#407b08">"action"</span><span style="color:#5f5f5f">:</span> mt5<span style="color:#5f5f5f">.</span>TRADE_ACTION_DEAL<span style="color:#5f5f5f">,</span><span style="color:#407b08">"symbol"</span><span style="color:#5f5f5f">:</span> pair<span style="color:#5f5f5f">,</span><span style="color:#407b08">"volume"</span><span style="color:#5f5f5f">:</span> <em><span style="color:#407b08">float</span></em><span style="color:#5f5f5f">(</span>size<span style="color:#5f5f5f">)</span><span style="color:#5f5f5f">,</span><span style="color:#407b08">"type"</span><span style="color:#5f5f5f">:</span> order<span style="color:#5f5f5f">,</span><span style="color:#407b08">"price"</span><span style="color:#5f5f5f">:</span> price<span style="color:#5f5f5f">,</span><span style="color:#407b08">"sl"</span><span style="color:#5f5f5f">:</span> sl<span style="color:#5f5f5f">,</span><span style="color:#407b08">"tp"</span><span style="color:#5f5f5f">:</span> tp<span style="color:#5f5f5f">,</span><span style="color:#407b08">"magic"</span><span style="color:#5f5f5f">:</span> <span style="color:#990055">234000</span><span style="color:#5f5f5f">,</span><span style="color:#407b08">"comment"</span><span style="color:#5f5f5f">:</span> <span style="color:#407b08">"My first trade"</span><span style="color:#5f5f5f">,</span><span style="color:#407b08">"type_time"</span><span style="color:#5f5f5f">:</span> mt5<span style="color:#5f5f5f">.</span>ORDER_TIME_GTC<span style="color:#5f5f5f">,</span><span style="color:#407b08">"type_filling"</span><span style="color:#5f5f5f">:</span> mt5<span style="color:#5f5f5f">.</span>ORDER_FILLING_IOC<span style="color:#5f5f5f">,</span>
<span style="color:#5f5f5f">}</span></code></span></span>

要发送请求，请使用order_send（）方法：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python">  result <span style="color:#c72c4c">=</span> mt5<span style="color:#5f5f5f">.</span>order_send<span style="color:#5f5f5f">(</span>request<span style="color:#5f5f5f">)</span></code></span></span>

最后，您将要检查您的订单是否成功。您可以转到MT5桌面应用程序并检查您的帐户，或者在order_send下添加以下代码来执行此操作：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><span style="color:#c72c4c">if</span> result<span style="color:#5f5f5f">.</span>retcode <span style="color:#c72c4c">!=</span> mt5<span style="color:#5f5f5f">.</span>TRADE_RETCODE_DONE<span style="color:#5f5f5f">:</span><span style="color:#c72c4c">print</span><span style="color:#5f5f5f">(</span><span style="color:#407b08">"Failed to send order :("</span><span style="color:#5f5f5f">)</span><span style="color:#c72c4c">else</span><span style="color:#5f5f5f">:</span><span style="color:#c72c4c">print</span> <span style="color:#5f5f5f">(</span><span style="color:#407b08">"Order successfully placed!"</span><span style="color:#5f5f5f">)</span></code></span></span>

要测试上面的代码是否有效，您需要调用这两种方法。在下面的示例中，我使用1标准手，300的止盈距离和100的止损距离开立EURUSD的交易：

<span style="color:#4c4c4c"><span style="color:#1f1e1e"><code class="language-python"><span style="color:#c72c4c">>></span><span style="color:#c72c4c">></span> connect<span style="color:#5f5f5f">(</span><span style="color:#990055">39672374</span><span style="color:#5f5f5f">)</span>

EURUSD found!

如果您回到MT5桌面应用程序，则应该在您的帐户上进行新交易：

您可以在此处看到买入价为1.21717，止损比买入价（1.21617）低100点，止盈为300（1.22017）多。
