FAQ
- Why net profit is lower than expected: the tool deducts all fees and tax items, not only price spread.
- Why small trades perform worse: minimum commission increases cost ratio in low-value orders.
- Why quantity was adjusted automatically: the value was not an integer or failed lot-size rules under current settings.
