Example of a trade: (you can check the profile for the response to the girl's quote, the data was taken from her trade)
How to calculate profit or loss:
What is needed:
Entry price
Exit price
Direction of the trade (long or short)
Position size
Formulas:
Long: (Exit − Entry) ÷ Entry × 100
Short: (Entry − Exit) ÷ Entry × 100
Multiply by 100 — to get in percentage
Profit/loss in $: Price difference × Volume
Example of profit (short):
Entry: 109,800
Exit: 109,600
Volume: 0.05 BTC
Profit: $10
In percentage: +0.18%
Example of loss (short):
Entry: 109,800
Exit: 110,200
Volume: 0.05 BTC
Loss: $20
In percentage: −0.36%
Long works similarly to short, just the order changes.
Example of profit (long):
Entry: 109,600
Exit: 109,800
Volume: 0.05 BTC
Profit in $: (109800 − 109600) × 0.05 = $10
Profit in %: (200 ÷ 109600) × 100 ≈ +0.18%
Example of loss (long):
Entry: 109,600
Exit: 109,400
Volume: 0.05 BTC
Loss in $: (109400 − 109600) × 0.05 = −$10
Loss in %: (−200 ÷ 109600) × 100 ≈ −0.18%
