After executing trades in batches, is the cost price you noted correct?
Let’s assume you buy the same asset in two steps: first 2 units at 10 USDT each; then 1 more unit at 16 USDT. Ignoring fees for now, your total spending is 36 USDT. You hold 3 units, so the average cost is 12 USDT.
If you simply add the two prices together and divide by two, you get 13—but that ignores that the two purchases involved different quantities. On your phone, you may only record one “looks right” price; then when you calculate profit and loss afterward, your starting point will be off.
This is only a cost-calculation exercise, not a suggestion to buy in batches. In practice, your records should also be cross-checked against the executed quantity, the executed amount, and which asset the fees were deducted from. If you only executed part of the order, you also can’t include the entire order’s total quantity.
Open the trade details and verify once by dividing the actual total spend by the actual executed quantity. If you get a result different from what the software shows, first check whether fees and other historical positions are included—don’t rush to treat the discrepancy as a system error.
