Trading calculators
Each of these runs the same arithmetic our own engine does — the sizing function the bot calls, the cost model the carry desk prices with, the expectancy formula behind the published track record. They are not generic formulas dressed up; they are the product’s own maths, exposed.
Each is paired with the guide that explains what it is doing, and each will tell you when the answer is “do not take this trade”. Nothing here is financial advice. Where a tool quotes a venue’s own numbers, our exchange-link disclosure says whether we are paid for naming it.
Calculators (4)
Funding carry calculator
What a delta-neutral carry position earns after the four taker legs it costs to open and close, and how long it must be held to clear them.
Position size calculator
Quarter-Kelly sizing with the same hard 2% cap our engine uses — including its refusal to size a negative edge at all.
Expectancy calculator
Expectancy, profit factor and the break-even win rate, so you can see why a 35% win rate can beat a 70% one.
Liquidation price calculator
Where an isolated-margin position closes, from the exchange's own maintenance-margin brackets rather than a flat percentage — with the three things it excludes named.
