Use Orvexa Trading as a reproducible worksheet for trading arithmetic. Start with the question the tool actually models, then keep its inputs and assumptions visible.
Follow the input sequence
- Enter cash available for this scenario, rather than borrowed buying power.
- Choose hypothetical entry, stop and target prices in the same currency.
- Enter per-side percentage fees and the tradable unit increment.
- Compare rounded units, required cash and modeled outcomes; verify actual broker rules.
Read the result in context
With $10,000 cash, a 1% budget, $50 entry, $48 stop, $56 target and 0.1% fees on each side, the model allows 47 whole units. Entry cash is $2,352.35 including its fee. The stop scenario loses $98.61 and the target scenario gains $277.02 after modeled fees. Neither outcome is a forecast.
Educational arithmetic only. No trading signals, leverage, derivatives, short positions, tax calculation or investment recommendation. A stop is not a guarantee of an execution price.
Keep your own record
Calculator numbers are not saved by the theme. Copy or print the record you need before closing the page. Reset restores the example, and a blank or invalid input produces an error message. The calculator requires JavaScript for live results; its written formula remains readable without it.
