租借ST5外汇交易平台：降低成本，提升竞争力

Sure! Here's a sample code in English for renting the ST5 forex trading platform, focusing on reducing costs and enhancing competitiveness:

```python

import st5 # Importing the ST5 forex trading platform library

def rent_st5_platform(duration: int) -> float:

"""

Rent the ST5 forex trading platform for the specified duration.

Args:

duration (int): Duration in months for which the platform is rented.

Returns:

float: Total cost of renting the platform.

"""

monthly_cost = 1000 # Cost per month for renting the ST5 platform

discount_rate = 0.1 # Discount rate for long-term rentals

if duration >= 12:

total_cost = duration * monthly_cost * (1 - discount_rate)

else:

total_cost = duration * monthly_cost

return total_cost

# Example usage

rental_duration = 6 # Renting the platform for 6 months

total_cost = rent_st5_platform(rental_duration)

print(f"The total cost of renting the ST5 platform for {rental_duration} months is ${total_cost}")

```

请注意，这只是一个示例代码，实际租用ST5外汇交易平台时，可能需要考虑其他因素，如授权和合法性等。此外，请根据实际情况调整代码中的价格和折扣率等参数。
