# GDEX: Trading UI Components

React component patterns for building trading interfaces with the GDEX SDK. Each component shows the props interface, SDK method it calls, and state management pattern.

## When to Use

- Building a spot or perp trading form
- Displaying open positions or orders
- Creating a copy trade management panel
- Showing PnL or orderbook data

## Prerequisites

- GDEX SDK context provider set up — see **gdex-ui-install-setup**
- Wallet sign-in via `AuthProvider.loginWithWallet()` — see **gdex-ui-wallet-connection**. It runs the managed-custody
  sign-in and exposes `creds` (`{ apiKey, walletAddress, sessionPrivateKey }`, walletAddress = control wallet) and
  `managedAddress`. Every write call below takes `creds`; `loginWithApiKey()` alone only covers read-only data.

## Spot Trade Form

```typescript
// components/SpotTradeForm.tsx
'use client';

import { useState } from 'react';
import { useGdex } from '@/providers/GdexProvider';
import { useAuth } from '@/providers/AuthProvider';

interface SpotTradeFormProps {
  defaultChain?: string;
  onTradeComplete?: (result: any) => void;
}

export function SpotTradeForm({ defaultChain = 'solana', onTradeComplete }: SpotTradeFormProps) {
  const { skill, isReady } = useGdex();
  const { creds } = useAuth();
  const [mode, setMode] = useState<'buy' | 'sell'>('buy');
  const [chain, setChain] = useState(defaultChain);
  const [tokenAddress, setTokenAddress] = useState('');
  const [amount, setAmount] = useState('');
  const [slippage, setSlippage] = useState(1);
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    if (!isReady || !creds) return;
    setLoading(true);
    setError(null);
    try {
      const chainArg = /^\d+$/.test(chain) ? Number(chain) : chain; // numeric ChainId or 'solana' / 'sui'
      const result = mode === 'buy'
        ? await skill.buyToken({ chain: chainArg, tokenAddress, amount, slippage, ...creds })
        : await skill.sellToken({ chain: chainArg, tokenAddress, amount, slippage, walletAddress: creds.walletAddress });
      onTradeComplete?.(result);
    } catch (err) {
      setError(err instanceof Error ? err.message : 'Trade failed');
    } finally {
      setLoading(false);
    }
  };

  return (
    <form onSubmit={handleSubmit} className="space-y-4">
      {/* Buy / Sell toggle */}
      <div className="flex gap-2">
        <button type="button" onClick={() => setMode('buy')}
          className={mode === 'buy' ? 'bg-green-600 text-white' : 'bg-gray-200'}>
          Buy
        </button>
        <button type="button" onClick={() => setMode('sell')}
          className={mode === 'sell' ? 'bg-red-600 text-white' : 'bg-gray-200'}>
          Sell
        </button>
      </div>

      {/* Chain selector */}
      <select value={chain} onChange={e => setChain(e.target.value)}>
        <option value="solana">Solana</option>
        <option value="8453">Base</option>
        <option value="42161">Arbitrum</option>
        <option value="1">Ethereum</option>
        <option value="56">BSC</option>
        <option value="sui">Sui</option>
      </select>

      <input placeholder="Token address" value={tokenAddress}
        onChange={e => setTokenAddress(e.target.value)} required />
      <input type="number" placeholder="Amount" value={amount}
        onChange={e => setAmount(e.target.value)} step="any" min="0" required />
      <input type="number" placeholder="Slippage %" value={slippage}
        onChange={e => setSlippage(Number(e.target.value))} step="0.1" min="0.1" max="50" />

      {error && <p className="text-red-500">{error}</p>}
      <button type="submit" disabled={loading || !isReady}>
        {loading ? 'Executing...' : `${mode === 'buy' ? 'Buy' : 'Sell'} Token`}
      </button>
    </form>
  );
}
```

**SDK methods called:** `skill.buyToken()`, `skill.sellToken()`

## Perp Order Form

```typescript
// components/PerpOrderForm.tsx
'use client';

import { useState } from 'react';
import { useGdex } from '@/providers/GdexProvider';
import { useAuth } from '@/providers/AuthProvider';

interface PerpOrderFormProps {
  onOrderPlaced?: (result: any) => void;
}

export function PerpOrderForm({ onOrderPlaced }: PerpOrderFormProps) {
  const { skill, isReady } = useGdex();
  const { creds } = useAuth();
  const [coin, setCoin] = useState('BTC');
  const [side, setSide] = useState<'long' | 'short'>('long');
  const [sizeUsd, setSizeUsd] = useState('');
  const [leverage, setLeverage] = useState(5);
  const [takeProfitPrice, setTakeProfitPrice] = useState('');
  const [stopLossPrice, setStopLossPrice] = useState('');
  const [loading, setLoading] = useState(false);
  const [error, setError] = useState<string | null>(null);

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    if (!isReady || !creds) return;
    setLoading(true);
    setError(null);
    try {
      // hlCreateOrder takes size in contracts (coin units): convert the USD notional at the mark price
      const mark = await skill.getHlMarkPrice(coin);
      const size = (Number(sizeUsd) / mark).toFixed(5); // round to the market's szDecimals in production
      const result = await skill.hlCreateOrder({
        coin,
        isLong: side === 'long',
        price: String(mark),
        size,
        isMarket: true,
        leverage,                   // sent top-level with the order
        tpPrice: takeProfitPrice,   // '' skips TP
        slPrice: stopLossPrice,     // '' skips SL
        ...creds,
      });
      onOrderPlaced?.(result);
    } catch (err) {
      setError(err instanceof Error ? err.message : 'Order failed');
    } finally {
      setLoading(false);
    }
  };

  return (
    <form onSubmit={handleSubmit} className="space-y-4">

## Copy Trade Panel

```typescript

  const [tab, setTab] = useState<'active' | 'discover'>('active');

  useEffect(() => {
    if (!isReady || !creds) return;
    // Load the user's copy trades (Solana sign-in; data = encrypted session key)
    skill.getCopyTradeList({
      userId: creds.walletAddress,
      data: buildGdexUserSessionData(sessionKey, creds.apiKey),
    }).then((r) => setActiveTrades(r.allCopyTrades ?? [])).catch(() => {});
    // Load top traders for discovery (no auth)
    skill.getCopyTradeWallets().then((w) => setTopTraders(w.slice(0, 10))).catch(() => {});
  }, [skill, isReady, creds, sessionKey]);

  return (
    <div>
      <div className="flex gap-2 mb-4">
        <button onClick={() => setTab('active')}
          className={tab === 'active' ? 'font-bold border-b-2' : ''}>
          Active ({activeTrades.length})

        </div>
      )}
    </div>
  );
}
```

**SDK methods called:** `skill.getCopyTradeList()`, `skill.getCopyTradeWallets()`

## PnL Display

```typescript
// components/PnLDisplay.tsx
interface PnLDisplayProps {
  value: number;
  label?: string;
  showSign?: boolean;
  currency?: string;
}

export function PnLDisplay({ value, label, showSign = true, currency = '$' }: PnLDisplayProps) {
  const isPositive = value >= 0;
  const formatted = `${showSign && isPositive ? '+' : ''}${currency}${Math.abs(value).toFixed(2)}`;

  return (
    <div className="text-center">
      {label && <p className="text-xs text-gray-500 mb-1">{label}</p>}
      <p className={`text-lg font-bold ${isPositive ? 'text-green-500' : 'text-red-500'}`}>
        {formatted}
      </p>
    </div>
  );
}
```

## Token Search with Autocomplete

```typescript
// components/TokenSearch.tsx
'use client';

import { useState, useCallback } from 'react';
import type { SupportedChain } from '@gemachdao/gdex-skill';
import { useGdex } from '@/providers/GdexProvider';
import { debounce } from '@/utils/debounce'; // simple debounce utility

interface TokenSearchProps {
  chain: SupportedChain;
  onSelect: (token: { address: string; symbol: string; name: string }) => void;
}

export function TokenSearch({ chain, onSelect }: TokenSearchProps) {
  const { skill, isReady } = useGdex();
  const [query, setQuery] = useState('');
  const [results, setResults] = useState<any[]>([]);

  const search = useCallback(
    debounce(async (q: string) => {
      if (!isReady || q.length < 2) { setResults([]); return; }
      const data = await skill.getTokenDetails({ chain, tokenAddress: q });
      setResults(data ? [data] : []);
    }, 300),
    [skill, isReady, chain]
  );

  return (
    <div className="relative">
      <input placeholder="Token address or symbol" value={query}
        onChange={e => { setQuery(e.target.value); search(e.target.value); }} />
      {results.length > 0 && (
        <ul className="absolute bg-white border rounded shadow-lg w-full z-10">
          {results.map((token, i) => (
            <li key={i} onClick={() => { onSelect(token); setResults([]); setQuery(token.symbol); }}
              className="p-2 hover:bg-gray-100 cursor-pointer">
              <span className="font-bold">{token.symbol}</span> — {token.name}
            </li>
          ))}
        </ul>
      )}
    </div>
  );
}
```

**SDK method called:** `skill.getTokenDetails()`

## Component → SDK Method Reference

| Component | SDK Method | Skill |
|-----------|------------|-------|
| `SpotTradeForm` | `buyToken()`, `sellToken()` | gdex-spot-trading |
| `PerpOrderForm` | `getHlMarkPrice()`, `hlCreateOrder()` | gdex-perp-trading |
| `PositionTable` | `getPerpPositions()`, `closePerpPosition()` | gdex-perp-trading |
| `CopyTradePanel` | `getCopyTradeList()`, `getCopyTradeWallets()` | gdex-copy-trading |
| `PnLDisplay` | (display only) | — |
| `TokenSearch` | `getTokenDetails()` | gdex-token-discovery |

## Backend Quirks Affecting UI (Live-Tested)

1. **Spot trading amounts in managed custody are RAW UNITS** (lamports/wei), not human-readable. The `SpotTradeForm` above uses `skill.buyToken()` which handles conversion, but if using `submitManagedPurchase()` directly, convert first.
2. **`hlCloseAll` is unreliable** — the `PositionTable` close button uses `closePerpPosition()` per coin (a reduce-only order for the live size), not `skill.hlCloseAll()`.
3. **Solana Meteora tokens fail** — if building a token selector, filter out `dexId === 'meteora'` tokens to avoid failed trades.
4. **Leverage goes on the order** — the slider value is passed as `leverage` to `hlCreateOrder()` (sent top-level with the order). The standalone `hlUpdateLeverage` endpoint returns 404.
5. **`getTopTraders()` needs numeric chainId** — use `622112261`, not `'solana'`.
