交易历史

StableFX 中的每笔外汇交易都遵循从报价请求（RFQ）到最终结算的定义生命周期。本页介绍 ForexTradeRecord 类型、ForexTradeStatus 生命周期，以及如何获取和显示交易历史。

交易生命周期

StableFX 交易按照以下状态流转：

  RFQ ──> QUOTED ──> MATCHED ──> SETTLED
   |         |          |
   |         |          +──> FAILED
   |         +──> FAILED
   +──> FAILED

状态	描述
RFQ	报价请求已提交。系统正在从流动性池中获取报价。
QUOTED	已收到报价。价格在短时间窗口内被锁定。
MATCHED	交易已与对手方匹配。结算进行中。
SETTLED	交易成功完成。资金已分配。
FAILED	交易在任何阶段失败。清算池中的资金将被退回。

ForexTradeStatus 类型

import type { ForexTradeStatus } from '@one_deploy/sdk';

type ForexTradeStatus = 'RFQ' | 'QUOTED' | 'MATCHED' | 'SETTLED' | 'FAILED';

ForexTradeRecord 类型

import type { ForexTradeRecord } from '@one_deploy/sdk';

interface ForexTradeRecord {
  /** Unique trade identifier. */
  id: string;

  /** The investment this trade belongs to. */
  investmentId: string;

  /** Currency pair traded, e.g. "EUR/USD". */
  currencyPair: string;

  /** Trade direction. */
  side: 'buy' | 'sell';

  /** Trade amount in base currency units. */
  amount: number;

  /** Quoted price at time of trade. */
  quotePrice: number;

  /** Execution price (may differ from quotePrice due to slippage). */
  executionPrice: number | null;

  /** Current trade status. */
  status: ForexTradeStatus;

  /** Realized profit or loss (in USDC), set after settlement. */
  pnl: number | null;

  /** Fee charged for this trade (in USDC). */
  fee: number;

  /** Slippage between quote and execution price (decimal). */
  slippage: number | null;

  /** ISO-8601 timestamp when the RFQ was submitted. */
  createdAt: string;

  /** ISO-8601 timestamp when the trade was last updated. */
  updatedAt: string;

  /** ISO-8601 timestamp when the trade was settled, if applicable. */
  settledAt: string | null;

  /** On-chain transaction hash, if applicable. */
  txHash: string | null;

  /** Reason for failure, if status is FAILED. */
  failureReason: string | null;
}

获取交易历史

交易记录可通过 useForexInvestments hook 的投资数据获取，也可直接通过 useForexTrading hook 获取。

使用 useForexTrading

import { useForexTrading } from '@one_deploy/sdk';

function useTradeHistory() {
  const { getTradeHistory } = useForexTrading();

  const fetchTrades = async (investmentId: string) => {
    const trades = await getTradeHistory({
      investmentId,
      limit: 50,
      offset: 0,
    });
    return trades;
  };

  return { fetchTrades };
}

追踪交易状态

你可以轮询进行中交易的状态更新：

import { useForexTrading } from '@one_deploy/sdk';
import type { ForexTradeRecord } from '@one_deploy/sdk';

function useTradeStatusPolling(tradeId: string, intervalMs: number = 3000) {
  const { getTradeById } = useForexTrading();
  const [trade, setTrade] = useState<ForexTradeRecord | null>(null);

  useEffect(() => {
    let active = true;

    const poll = async () => {
      const updated = await getTradeById(tradeId);
      if (!active) return;
      setTrade(updated);

      // Stop polling when trade reaches a terminal status
      if (updated.status === 'SETTLED' || updated.status === 'FAILED') {
        return;
      }

      setTimeout(poll, intervalMs);
    };

    poll();
    return () => { active = false; };
  }, [tradeId, intervalMs, getTradeById]);

  return trade;
}

// Usage
function TradeStatusTracker({ tradeId }: { tradeId: string }) {
  const trade = useTradeStatusPolling(tradeId);

  if (!trade) return <Text>Loading...</Text>;

  return (
    <View style={{ padding: 16 }}>
      <Text style={{ color: '#fff', fontSize: 16 }}>
        Trade {trade.id.slice(0, 8)}...
      </Text>
      <Text style={{ color: getStatusColor(trade.status), marginTop: 8 }}>
        Status: {trade.status}
      </Text>
      {trade.status === 'SETTLED' && (
        <Text style={{ color: '#44cc88', marginTop: 4 }}>
          Settled at {new Date(trade.settledAt!).toLocaleString()}
        </Text>
      )}
    </View>
  );
}
