The Impact Calculator helps you estimate how a trade could affect price and market cap based on current pool depth before you execute it. It's accessible from the Strategies page via the calculator icon.

## How to Use

1. Go to your profile's **Strategies** tab
2. Click the **calculator icon** next to the Create Strategy button
3. Configure the scenario and review the results

## Configuration

### Trade Side

Select **Buy** or **Sell** to simulate the direction of the trade.

### Trade Size

Enter the size of the trade you want to simulate. Select the unit: **USD**, **Quote/Native** (e.g. SOL, USDC, WETH), or **Token**.

### Market Flow

Simulate additional market pressure alongside your trade:

* **Negative (%)** — Additional flow offsets your simulated trade
* **Positive (%)** — Additional flow moves in the same direction as your simulated trade
* **0%** — No additional market pressure, just your trade

Use the slider or type a value directly. The slider gradient goes from red (negative) to green (positive).

## Results

Once calculated, the Impact Calculator shows:

| Metric                 | Description                                               |
| ---------------------- | --------------------------------------------------------- |
| **Token Flow**         | How many tokens move in/out (shown with +/- prefix)       |
| **Quote Flow**         | How much quote asset (e.g. SOL, WETH) moves in/out        |
| **Current Price**      | The token's current price in USD                          |
| **Current Market Cap** | The token's current market cap                            |
| **Price Delta**        | How much the price changes (absolute and percentage)      |
| **Market Cap Delta**   | How much the market cap changes (absolute and percentage) |
| **Final Price**        | Projected price after the trade                           |
| **Final Market Cap**   | Projected market cap after the trade                      |

Positive deltas show a green up arrow, negative deltas show a red down arrow.

If the trade size may be too large for current liquidity, a warning is displayed and the estimate may be less reliable.

## Use Cases

* **Size your trades** — Check how much a $10K buy would move the price before executing
* **Plan DCA amounts** — Find the right trade size that moves the price without excessive impact
* **Evaluate counter-trade settings** — Understand the impact of different capture percentages
* **Scenario planning** — Model how your trades perform under different market flow conditions
