Prices and commissions
Trade Math separates instrument prices from transaction costs: prices describe the market, commissions are values supplied by the user.
2. Enter commissions
Use the Commission fields for the total order or contract cost indicated by the label. Before an order you can enter your own estimate; after execution, prefer the broker's actual cost.
3. Blank fields and actual costs
A blank commission field counts as 0. When you know the actual cost of an executed order, enter it: Trade Math uses that value and does not replace it with an automatic estimate.
4. Special costs
Some tools distinguish normal commissions from special exercise, assignment or settlement costs. Enter them only when they are relevant to the trade.
Average price and cost basis
When an average price already includes historical commission, do not enter that commission again. With an execution-only average, enter historical cost separately when requested.
Futures margin
Futures margin is not a commission. Enter the broker/exchange requirement separately from opening and closing costs.
