Script Samples
=======
1. Buy or sell a product
   ```python
    errid, order_uid = Buy(volume=volume, price=Ask())
    errid, order_uid = Sell(volume=0.01, price=Bid())
   ```

2. Modify an order
   ```python
    errid, order_uid = ModifyOrder(order_uid, stop_loss=stop_loss, take_profit=take_profit)
   ```

3. Close an order
   ```python
    errid, order_uid = CloseOrder(order_uid, price=Ask(), volume=volume)
   ```

4. Get the current open order UIDs
   ```python
    uids = GetOpenedOrderUIDs()
    for uid in uids:
        o = GetOrder(uid)
   ```
