Before accepting, compare whether the items you receive are actually wanted by other traders.
Recheck fluctuating items. A close result can move when one side is unstable.
Worked trade example
Read the value gap before you judge the trade.
The result compares the two totals using the larger side as the baseline. A gap of five percent or less stays in the fair range; a larger gap shows which side receives more listed value. Use the percentage instead of the raw point gap when totals change: a 10-point difference is large against 100, but minor against 1,000. That keeps the label consistent across trades of very different sizes.
Build both sides exactly
Suppose the items you offer total 100 and the items you receive total 96. The difference is 4, and 4 divided by the larger total of 100 gives a 4% value gap. The checker labels that result Fair range. Include every duplicate and small add before trusting the total.
Check the direction
If you offer 100 and receive 110, the 10-point difference is about 9% of the larger total. That is a Win by value for you. Reverse the sides and the same gap becomes a loss by value. The label describes the current listed totals, not a guaranteed market outcome.
Make the second decision
After the arithmetic, compare demand, stability, and retrade difficulty. A fair-range offer can still be weak when the received items are difficult to move. A value win can also be reasonable to reject when it depends on unstable items or many low-demand adds.
Calculator FAQ
How to read the trade result
How does the MM2 trade checker work?
Add every item and quantity on both sides. The trade checker totals the current listed values, shows the difference, and labels the result as a win, fair range, or loss by value.
What counts as a fair MM2 trade?
The calculator treats a value gap of five percent or less as a fair range. Demand, stability, item preference, and retrade difficulty still need a separate check.
Do duplicate items change the trade result?
Yes. Each quantity is multiplied by the item's current value, so duplicate weapons, pets, and small adds all affect the final total.
Why can an equal-value trade still be bad?
Equal totals do not measure demand or how easy an item is to trade again. Compare those factors before treating the calculator result as the final decision.
