I. Profit and Loss (PnL) Calculations
Case:
Using the PnL calculations for BIST100/TRY as an example, where the quote currency is TRY and the margin is USDT.
User A opens a long position with 100 USDT (5x leverage) on BIST100/TRY at a price of 8,000. At the position opening time, 1 USDT = 30 TRY.

PnL Calculations |
PnL |
|
Time 1 |
10,000 |
30 |
= [1 * 100 * 5 * 30 * (10,000 - 8,000) / 8,000] / 30 |
+125 USDT |
|
Time 2 |
10,000 |
25 |
= [1 * 100 * 5 * 30 * (10,000 - 8,000) / 8,000] / 25 |
+150 USDT |
|
Time 3 |
10,000 |
35 |
= [1 * 100 * 5 * 30 * (10,000 - 8,000) / 8,000] / 35 |
+107.14 USDT |
|
Time 4 |
12,000 |
35 |
= [1 * 100 * 5 * 30 * (12,000 - 8,000) / 8,000] / 35 |
+214.29 USDT |
Based on the example above, it can be observed that:
-
PnL will change with the changes of USDT/TRY exchange rate, even when the price of the pair remains unchanged.
-
User's profits will increase when the USDT/TRY exchange rate drops. Conversely, profits will decrease as the USDT/TRY exchange rate rises.
-
When the price of BIST100/TRY fluctuates, the final PnL will be calculated based on the current exchange rate of USDT/TRY for opening and closing positions.
II. Exchange Rate Calculations for Open/Close Positions When Using Fiat as Quote Currency
-
When opening position: The user opens a position using USDT as principal, which is then converted to TRY to be used as the margin, based on the TRY/USDT exchange rate during the position opening time. The position amount will be determined according to the chosen leverage.
-
When closing position: PnL will be calculated in TRY based on the BIST100/TRY price. The PnL amount in TRY is then converted into USDT using the TRY/USDT exchange rate during the position closing time to calculate the realized PnL.
