For every order completed successfully, the broker may charge a certain fee, which is usually a small fraction of the price at which the instrument was bought or sold. While the amount may seem small, it is important to keep track of the brokerage as it may end up eating a significant chunk of your profit at the end of the day.
The brokerage that's charged varies from broker to broker and also from segment to segment. For the purpose of this recipe, we will consider a brokerage of 0.01%.
How to do it…
We execute the following steps to complete this recipe:
- Calculate the brokerage that's charged per trade:
>>> entry_price = 1245
>>> brokerage = (0.01 * 1245)/100
>>> print(f'Brokerage charged per trade: {brokerage:.4f}')
We'll get the following output:
Brokerage charged per trade: 0.1245
- Calculate the total brokerage that's charged for 10 trades:
>>> total_brokerage = 10 * (0.01 * 1245) / 100
>>> print(f'Total Brokerage charged for 10 trades: \
{total_brokerage:.4f}')
We'll get the following output:
Total Brokerage charged for 10 trades: 1.2450
How it works…
In step 1, we start with the price at which a trade was bought or sold, entry_price. For this recipe, we have used 1245. Next, we calculate 0.01% of the price, which comes to 0.1245. Then, we calculate the total brokerage for 10 such trades, which comes out as 10 * 0.1245 = 1.245.
