Frequently Asked Questions
What does a pre-trade check calculate?
It runs four calculations at once: recommended position size based on your risk tolerance, breakeven price including fees, liquidation distance, and total funding cost for your planned hold time.
What is the "risk %" field?
The percentage of your account balance you are willing to lose if the stop-loss is hit. For example, 1% risk on a $10,000 account means you risk $100 on this trade.
How is position size calculated from stop-loss and risk?
Position size = (account balance × risk%) / (|entry − stop-loss| / entry). The formula sizes the trade so the stop-loss loss equals exactly your risk budget.
What does "Safety" mean in the results?
Safety classifies the setup: Clear means liquidation is far and costs are low, Warn means the liquidation price is close or funding is high, Impossible means the position cannot be opened with your current parameters.
Why does the funding cost change when I change hold time?
Funding is charged every 8 hours (or 1 hour on some exchanges). Total funding cost = position size × funding rate × (hold hours / interval hours). Longer holds multiply the cost linearly.
