About
A browser model of hypothetical profit/loss for crypto perpetual positions. Changing size and direction changed exposure labels and the settled chart in a trial. It does not establish real fills, strategy returns or liquidation accuracy.
At a glance
Perp Simulator plots hypothetical profit and loss for long/short crypto perpetual positions. It is worth trying to understand how a change in position size or direction changes exposure, without placing a trade. Our smaller short example reversed the settled chart’s slope and changed the net-exposure label. That is a scenario calculation, not evidence of real fills, future funding or liquidation behaviour.
Good fit
Someone learning to read a position’s exposure before attempting more complicated combinations. A leg has an asset, entry price, USD position size, leverage and a funding assumption. Settings expose fees and slippage, making the model’s inputs easier to question. The size field is labelled position size; do not automatically treat it as the cash collateral you would deposit.
Consider something else when
You need a broker, execution simulator, verified liquidation model or an assurance that a strategy will work. Venue rules, fees, liquidity and changing funding can make a real outcome differ from a simplified chart. The available Backtest and Top Pairs tabs were not evaluated, so this guide makes no claim about historical strategy quality.
Start here
Inspect Open trading settings, then change one hypothetical input at a time. We changed the default example from $10,000 long to $1,000 short, waited for the chart animation to settle, and restored the original. The exposure labels and slope changed as expected. No wallet, order, share link or personal position was supplied.
Cost and requirements
The public browser model opened without an account or payment. The policy describes client-side calculations, while market data comes from external venues. It also discloses IP processing for rate limits and anonymous usage analytics. Browser calculation is therefore not a claim that using the site makes no network requests.
Limits to know
The inspected defaults included a taker-fee assumption, zero slippage and funding enabled. These are model settings, not a verified quote for your account or future period. Research covered a single-leg direction/size change and the policy pages; it did not assess leverage calculations, liquidation, correlated multi-leg scenarios, backtests or venue-data reliability.

What it can do
Update the position exposure chart
Hypothetical asset, direction and USD size → Scenario P&L and net-bias display
Adjust documented simulation assumptions
Modeled fee/slippage/funding settings → Hypothetical results, not executed trades or verified liquidation calculations
Why it made the leaderboard
Helps users inspect how position inputs change a hypothetical exposure chart. Model fees/funding and external data are assumptions to check, rather than evidence a real trade will behave the same way.
