Size positions precisely with the Pacifica Risk Manager

The Risk Manager is a professional position sizing calculator designed for disciplined perpetuals trading on Pacifica. Enter your account size, risk percentage, entry price, and stop loss, and the calculator instantly returns the exact number of contracts to trade so that a stop-loss hit costs you precisely your chosen risk amount — no more. It also projects the required margin, estimated liquidation price, take-profit levels at multiple risk:reward ratios, Expected Value, and the daily and weekly cost of holding the position through funding payments. When you are ready, you can execute the calculated trade directly on Pacifica DEX with a single click.

Calculator inputs

The calculator panel sits in the center of the Risk Manager layout. All fields update results in real time with a 350-millisecond debounce, so you do not need to press a calculate button. Direction A Long / Short toggle at the top sets the trade direction. The toggle controls which side of the stop loss is valid and how liquidation price is computed. Account size Your total account equity in USDC. When your wallet is connected, this field auto-fills from your live account equity. You can override it manually at any time. Risk % per trade A slider from 0.5% to 10% that sets how much of your account you are willing to lose if the stop loss is hit. The dollar equivalent updates next to the slider as you drag. A color indicator shows safe (green ≤ 2%), moderate (amber ≤ 5%), and high (red > 5%) risk levels. Entry price The price at which you plan to enter the trade. Auto-fills from the current mark price of the selected market when you switch symbols. Click Mark to reset to the live price at any time. Stop loss Your stop loss price. Use the quick-set buttons to place the stop at a fixed percentage below (long) or above (short) the entry price: You can also type an exact price directly into the stop loss field. Take profit Switch between R:R mode and Manual mode using the toggle above the field.

• R:R mode — a slider from 1:1 to 1:10 automatically calculates the take profit price that achieves the selected risk:reward ratio. Quick buttons let you jump to 1:1, 1:2, 1:3, 1:5, and 1:10.
• Manual mode — type an exact take profit price.

Leverage A slider from 1x to the market maximum. The selected leverage affects the required margin and the estimated liquidation price. A warning banner appears when leverage exceeds 70% of the market maximum.

Calculator outputs

Results appear in the panel to the right of the calculator once entry price and stop loss are filled in. Risk:Reward and Expected Value card Shows the R:R ratio as a visual bar (red for risk, green for reward) alongside the Expected Value in dollars. EV is computed as (win rate × reward) − (loss rate × risk). You can adjust the assumed win rate using a percentage input field; the EV updates immediately. Position size Risk / Reward levels Price level diagram A visual bar maps all four key prices — liquidation, stop loss, entry, and take profit — on a single axis so you can see their relative spacing at a glance. The danger zone (entry to stop) is shaded red; the profit zone (entry to take profit) is shaded green. Funding cost The funding rate used is the live rate for the selected market, sourced directly from the Pacifica API.

Portfolio risk tab

The Portfolio tab is available when your wallet is connected and shows a live aggregate view of all your open positions. Summary cards Risk exposure bar A gradient bar (green to red) with a marker showing your current portfolio risk percentage. Reference lines mark the safe (< 10%), moderate (10–25%), and high (> 25%) thresholds. Position heat map Each open position is rendered as a bubble. Bubble size is proportional to the position’s USD value; bubble color reflects unrealized PnL (green for profit, red for loss, with intensity scaling with magnitude). Click any bubble to open a detail modal that shows mark price, entry price, liquidation price, distance to liquidation, leverage, and funding paid for that position. Long / short breakdown A split bar showing the proportion of total notional value in long positions versus short positions, with the dollar amounts for each side and the net directional exposure below. Correlation warnings The portfolio tab detects when you hold two or more positions in correlated asset groups (BTC, ETH, altcoins, meme coins, and others). A warning banner appears for each group with same-direction positions, highlighting the concentration risk of effectively running a larger single-asset bet.
