+
+```mql4
+void OnTick() {
+    //
+    if (OrdersTotal() > 0) {
+        return;
+    }
+
+    //
+    // we are on bullish candle ...
+    if (close[1] > open[1]) {
+        //
+        OrderSend(
+            _Symbol, // Symbol ...
+            OP_BUY, // Operation ...
+            0.1 // Lot Size ( Volume ) ...
+            Ask, // Open Order Price ...
+            3, // tolerance ...
+            Ask - 300 * _Point, // SL ...
+            Ask + 150 * _Point, // TP ...
+            NULL, // Trade Comment ...
+            0, // Magic Number (user unique number) ...
+            0, // Expiration ...

+int CountOpenBuyOrders() {
+    //
+    int result = 0;
+
+    //
+    for (int i = OrdersTotal() - 1; i >= 0; i--) {
+        //
+        OrderSelect(i, SELECT_BY_POSITION, MODE_TRADES);
+
+        //
+        string orderSymbol = OrderSymbol();
+
+        //
+        if (
+            orderSymbol == _Symbol && 
+            OrderType() == OP_BUY
+        ) {
+            result++;
+        }
+    }
+
+    //
+    return result;
+}
