Polymarket API 快速使用教程

基于 FMZ 平台(托管者版本3.8.8)，快速上手 Polymarket API。

Symbol 格式

Symbol 必须以 exchange.GetMarkets() 返回的键值为准，此函数第一次调用很慢，之后有缓存, 格式为：

            
            
            
{marketSlug}_USDC.(Yes/No)

示例：

            
            
            
will-the-next-prime-minister-of-hungary-be-istvn-kapitny_USDC.No

• Yes 代币 = 押注事件会发生
• No 代币 = 押注事件不会发生
• 价格范围 0~1，代表市场认为的概率（0.65 = 65%）

场景1：获取所有市场（获取有效symbol）

            javascript
            
            
var markets = exchange.GetMarkets();
for (var symbol in markets) {
    var m = markets[symbol];
    Log(symbol);  // 这就是下单用的symbol
    Log("  问题:", m.Info.question);
    Log("  24h量:", m.Info.volume24hr);
}

场景2：获取行情

            javascript
            
            
// symbol必须从GetMarkets()的key中获取
var symbol = "will-the-next-prime-minister-of-hungary-be-istvn-kapitny_USDC.Yes";

// ticker
var t = exchange.GetTicker(symbol);
Log("最新价:", t.Last, "买一:", t.Buy, "卖一:", t.Sell);

// 深度
var d = exchange.GetDepth(symbol);
Log("卖一:", d.Asks[0].Price, d.Asks[0].Amount);
Log("买一:", d.Bids[0].Price, d.Bids[0].Amount);

场景3：查账户和持仓

            javascript
            
            
// 账户
var acc = exchange.GetAccount();
Log("可用:", acc.Balance, "USDC");

// 持仓
var pos = exchange.GetPositions();
for (var i = 0; i < pos.length; i++) {
    Log(pos[i].Symbol, "数量:", pos[i].Amount, "盈亏:", pos[i].Profit);
}

场景4：下单

            javascript
            
            
// symbol必须从GetMarkets()获取
var symbol = "{some-market}_USDC.Yes";

// 市价买入 10 USDC
exchange.CreateOrder(symbol, "buy", -1, 10);

// 限价买入
exchange.CreateOrder(symbol, "buy", 0.55, 20);

// 卖出
exchange.CreateOrder(symbol, "sell", -1, 10);

场景5：查单/撤单

            javascript
            
            
// 查询订单
var order = exchange.GetOrder(orderId);
Log("状态:", order.Status, "成交:", order.DealAmount);

// 撤单
exchange.CancelOrder(orderId);

// 所有未成交订单
var orders = exchange.GetOrders();

场景6：清仓

            javascript
            
            
var pos = exchange.GetPositions();
for (var i = 0; i < pos.length; i++) {
    if (pos[i].Amount > 0) {
        exchange.CreateOrder(pos[i].Symbol, "sell", -1, pos[i].Amount);
    }
    Sleep(500);
}

场景7：redeem招回

            javascript
            
            
var items = _C(exchange.GetPositions);
items.forEach(item => {
    if (item.Info.redeemable) {
        Log(item.Symbol, item.Info.eventSlug)
        Log(exchange.IO("redeem", item.Symbol, true))
    }
})

场景8：遍历市场找低概率标的

            javascript
            
            
var markets = exchange.GetMarkets();
for (var symbol in markets) {
    if (!symbol.endsWith("-YES")) continue;
    var prices = JSON.parse(markets[symbol].Info.outcomePrices || "[]");
    var yesPrice = parseFloat(prices[0] || 0);
    if (yesPrice < 0.3 && yesPrice > 0.05) {
        Log(symbol, "YES价格:", (yesPrice * 100).toFixed(1) + "%");
    }
}

常用API
