# Forecast Leverage SDK
2+
3+
Add leverage to Polymarket trading. Target-based UX, comprehensive validation, production-ready.
4+
5+
```typescript
6+
const position = await sdk.openTargetPosition({
7+
marketConditionId: '0x...',
8+
longYes: true,
9+
currentPrice: 0.40, // 40¢
10+
targetPrice: 0.44, // 44¢
11+
timeframeSeconds: 3600,
12+
capitalUSDC: 1000,
13+
maxSlippageBps: 100
14+
});
15+
// Returns: 8.2x leverage, $25 fees, +$305 PnL at target
16+
```
17+
18+
## Install
19+
20+
```bash
21+
npm install @forecast-protocol/leverage-sdk
22+
```
23+
24+
## Quick Start
25+
26+
```typescript
27+
import { ForecastLeverageSDK } from '@forecast-protocol/leverage-sdk';
28+
29+
const sdk = new ForecastLeverageSDK(
30+
rpcUrl,
31+
privateKey,
32+
protocolAddress,
33+
usdcAddress,
34+
ctfAddress,
35+
polymarketCreds,
36+
funderAddress
37+
);
38+
39+
// Simulate first (recommended)
40+
const preview = await sdk.simulatePosition(params);
41+
console.log(`${preview.effectiveLeverage}x leverage, $${preview.fees.total} fees`);
42+
43+
// Execute
44+
const position = await sdk.openTargetPosition(params);
45+
46+
// Close
47+
await sdk.closePosition(position.legIds);
48+
```
49+
50+
## Examples
51+
52+
- [Basic Usage](examples/basic.ts) - Open and close a position
53+
- [Simulation](examples/simulation.ts) - Test without real transactions
54+
- [Error Handling](examples/errors.ts) - Handle all error cases
55+
- [UI Integration](examples/ui.ts) - React component example

62+
63+
## Error Handling
64+
65+
```typescript
66+
try {
67+
await sdk.openTargetPosition(params);
68+
} catch (error) {
69+
if (error instanceof ValidationError) {
70+
// Bad input - fix parameters
71+
} else if (error instanceof PolymarketError) {
72+
// Order failed - check liquidity
73+
} else if (error instanceof ProtocolError) {
74+
// Protocol issue - check network
75+
}
76+
}
77+
```
78+
79+
## Features
