宏观数据与预测市场相匹配的地方

预测市场已经从好奇心转向基础设施. 卡尔希 美国首家由CFTC监管的预测交易所, 允许您交易"will 美国CPI 超过3.5%在4月份?"或"将 美国联邦储备 Polymarket 在 Polygon 区块链上运行,提供类似的二进制结果市场,在全球开放式访问下进行宏观事件. 美元/日元没有人知道. 欧元/美元其他外汇公司.

如果您已经使用FXMacroData来跟踪央行日历,监控CPI惊喜,并抽取政策利率历史,您有必要的原材料来建立这些市场的系统优势.本指南将向您展示如何连接点:从FXMacrodata抽取结构化宏观数据,将其映射到开放预测市场合约,并在Python中构建可重复的决策工作流.

目标
通过FXMacroData将即将到来的宏观公告与Kalshi和Polymarket的相关预测市场合约匹配,并从历史惊喜数据计算方向信号,以帮助您了解位置.

预先要求

  • 一个FXMacroData API 键 在这里订阅 免费试用.
  • 通过Python 3.10或更高版本 requests 已经安装 (pip install requests) 没有.
  • 卡尔希账户启用API访问,或者是Polymarket钱包进行手动交叉引用.
  • 基本熟悉CPI的内容, 农业以外的工资没有 政策利率 决策是这样的.

步骤1 拉下一个发布日历

首先,您需要清楚地了解什么发布会和何时发布.FXMacroData的发布日历终点返回货币的所有预定宏观事件,以及预期日期和发布时间.

import requests

API_KEY = "YOUR_API_KEY"
BASE = "https://fxmacrodata.com/api/v1"

def get_upcoming_releases(currency: str) -> list[dict]:
    url = f"{BASE}/calendar/{currency}?api_key={API_KEY}"
    resp = requests.get(url, timeout=10)
    resp.raise_for_status()
    return resp.json().get("data", [])

usd_calendar = get_upcoming_releases("usd")

for event in usd_calendar[:5]:
    print(event["indicator"], event.get("announcement_datetime"), event.get("next_release_date"))

每个条目都带有一个 indicator (例如: inflation没有人知道. non_farm_payrolls没有人知道. policy_rate,作为Unix时间的预定公告时间,以及下一个预期发布日期.这是您过开放预测市场合约的主要输入.


步骤2 获取历史公告数据并计算惊喜序列

预测市场价格概率基于可用信息. 如果您可以计算给定指标的近期惊喜指数,实际打印的共识是多少次,以及您有多少的基线来校准您的位置. 从公告终点从过去十二个月的实际与预测数据中提取:

def get_announcement_history(currency: str, indicator: str, limit: int = 24) -> list[dict]:
    url = f"{BASE}/announcements/{currency}/{indicator}?api_key={API_KEY}&limit={limit}"
    resp = requests.get(url, timeout=10)
    resp.raise_for_status()
    return resp.json().get("data", [])

def compute_surprise_series(records: list[dict]) -> list[dict]:
    surprises = []
    for r in records:
        actual = r.get("actual_value")
        consensus = r.get("predicted_value")
        if actual is not None and consensus is not None:
            surprises.append({
                "date": r["date"],
                "actual": actual,
                "consensus": consensus,
                "surprise": actual - consensus,
                "direction": "beat" if actual > consensus else "miss",
            })
    return surprises

cpi_history = get_announcement_history("usd", "inflation", limit=24)
cpi_surprises = compute_surprise_series(cpi_history)

beat_count = sum(1 for s in cpi_surprises if s["direction"] == "beat")
miss_count = len(cpi_surprises) - beat_count
print(f"CPI beat rate (last 24 releases): {beat_count}/{len(cpi_surprises)} = {beat_count/len(cpi_surprises):.0%}")

没有什么. predicted_value 每个公告记录上的字段存储了权威来源的市场共识 (费城联邦储备局对美元指标的专业预测者调查). 这也是同一个准预测市场定价的共识信号,因此您的惊喜系列将与卡尔希CPI合约中的隐含概率直接相比.


步骤3 预测市场合约的地图指标

卡尔希和波利马克特都将其宏观合约围绕特定指标值构建起来.一旦您了解FXMacroData指标的,映射就很简单.下面是一个最流动合约的参考表:

预测市场合约类型 汇率指标 货币 应用程序文件
价格指数会超过X%吗? inflation 美元 美国美元/通货膨胀
核心价格指数将超过X%? core_inflation 美元 美国美元/核心通货膨胀
否则,我们将会有更多的问题. non_farm_payrolls 美元 农业工资人数
美国联邦储备委员会是否会减持或维持? policy_rate 美元 美国美元/政策_利率
国内生产总值增长将超过X%吗? gdp_quarterly 美元 美国人民币/GDP_季度
失业率会下降到X%以下吗? unemployment 美元 美国美元/失业
欧洲央行是否会在下一次会议上降息? policy_rate 欧元 欧元/政策_利率

没有什么. 发布日程 查看所有这些指标表单一视图. 当卡尔希合约列出解决日期时,与 next_release_date 根据FXMacroData日历确认他们根据相同的基本公告解决.不匹配,即合同根据预估和最终修订解决是误价的常见来源.


步骤4 查询共识定预测终点

汇丰MacroData的预测终点提供了来自官方调查数据的前性共识值,这些调查是预测市场参与者用来固他们的先验的. 抽取下一次CPI发布的当前共识,并将其与开放卡尔希合约的门进行比较:

def get_predictions(currency: str, indicator: str) -> list[dict]:
    url = f"{BASE}/predictions/{currency}/{indicator}?api_key={API_KEY}"
    resp = requests.get(url, timeout=10)
    resp.raise_for_status()
    return resp.json().get("data", [])

cpi_predictions = get_predictions("usd", "inflation")

# Most recent upcoming prediction
if cpi_predictions:
    next_pred = cpi_predictions[0]
    for p in next_pred.get("predictions", []):
        print(f"Source: {p['prediction_source_label']}")
        print(f"Consensus: {p['predicted_value']}%")
        print(f"For release date: {next_pred['date']}")

样本反应的形状:

{
  "currency": "USD",
  "indicator": "inflation",
  "count": 1,
  "prediction_count": 1,
  "data": [
    {
      "announcement_id": "usd_inflation_2026-05-14",
      "currency": "usd",
      "indicator": "inflation",
      "date": "2026-05-14",
      "announcement_datetime": 1747216200,
      "predictions": [
        {
          "predicted_value": 2.8,
          "prediction_type": "market_consensus",
          "prediction_source": "philly_fed_spf",
          "prediction_source_label": "Philadelphia Fed Survey of Professional Forecasters"
        }
      ]
    }
  ]
}

如果卡尔希合约问"4月CPI将会超过2.9%吗?"而SPF共识为2.8%,你现在有一个量化起点:共识表示没有,并且有0.1个百分点缓冲.从第二步的历史惊喜系列告诉你CPI有多少次超过了共识0.1百分點,给你一个实证的基率,可以与合同的隐含概率进行比较.


步骤5 建立完整的决策信号

将三个输入组合成一个单一的决策函数.逻辑是故意简单的目标是可重复的,数据基础的信号,而不是一个黑盒:

def prediction_market_signal(
    currency: str,
    indicator: str,
    contract_threshold: float,
    contract_direction: str,  # "above" or "below"
    lookback: int = 24,
) -> dict:
    """
    Returns a signal dict for a prediction market contract.

    contract_threshold: the numeric threshold in the contract question
                        (e.g. 2.9 for "Will CPI exceed 2.9%?")
    contract_direction: "above" means YES if actual > threshold
    """
    history = get_announcement_history(currency, indicator, limit=lookback)
    surprises = compute_surprise_series(history)
    predictions = get_predictions(currency, indicator)

    consensus = None
    release_date = None
    if predictions:
        latest_preds = predictions[0].get("predictions", [])
        if latest_preds:
            consensus = latest_preds[0]["predicted_value"]
            release_date = predictions[0]["date"]

    # Base rate: how often did actual exceed the threshold historically?
    actuals_above = sum(1 for r in history if r.get("actual_value") is not None
                        and r["actual_value"] > contract_threshold)
    base_rate = actuals_above / len(history) if history else None

    # Surprise bias: mean surprise (positive = beat)
    mean_surprise = (sum(s["surprise"] for s in surprises) / len(surprises)
                     if surprises else None)

    # Directional signal
    if consensus is not None:
        buffer = consensus - contract_threshold  # positive = consensus above threshold
        signal = "NO" if (contract_direction == "above" and buffer > 0) else "YES"
    else:
        signal = "NEUTRAL"

    return {
        "currency": currency.upper(),
        "indicator": indicator,
        "contract_threshold": contract_threshold,
        "contract_direction": contract_direction,
        "consensus": consensus,
        "release_date": release_date,
        "historical_base_rate_above_threshold": base_rate,
        "mean_surprise_last_n": mean_surprise,
        "lookback": lookback,
        "signal": signal,
    }


result = prediction_market_signal(
    currency="usd",
    indicator="inflation",
    contract_threshold=2.9,
    contract_direction="above",
    lookback=24,
)

import json
print(json.dumps(result, indent=2))

输出示例:

{
  "currency": "USD",
  "indicator": "inflation",
  "contract_threshold": 2.9,
  "contract_direction": "above",
  "consensus": 2.8,
  "release_date": "2026-05-14",
  "historical_base_rate_above_threshold": 0.33,
  "mean_surprise_last_n": 0.04,
  "lookback": 24,
  "signal": "NO"
}

阅读:共识为2.8% (低于2.9%的门),CPI打印超过2.9%24次发布的历史基率为33%,平均惊喜是温和的0.04ppt上升偏差.原始信号是NO,但基率和惊喜偏差的组合告诉你,这不是一个高信念的瘦调整位置大小.


步骤6 扩展到非美元和跨市场合同

预测市场越来越多地列出非美元宏观事件的合约:欧洲央行决定,英国CPI,日本银行政策和澳大利亚就业.FXMacroData通过相同的终点结构覆盖所有这些.

# ECB rate decision signal
ecb_signal = prediction_market_signal(
    currency="eur",
    indicator="policy_rate",
    contract_threshold=3.15,   # "Will ECB rate fall below 3.15%?"
    contract_direction="below",
    lookback=12,
)

# UK inflation signal
uk_cpi_signal = prediction_market_signal(
    currency="gbp",
    indicator="inflation",
    contract_threshold=2.5,
    contract_direction="above",
    lookback=18,
)

# Australian employment signal
aus_employment_signal = prediction_market_signal(
    currency="aud",
    indicator="employment",
    contract_threshold=30.0,   # thousands, "Will employment add 30K+?"
    contract_direction="above",
    lookback=18,
)

没有什么. 欧元/美元 现在我 汇率汇率 仪表板显示每个货币对的政策利率历史和CPI趋势,在承诺之前给您视觉上下文检查. 欧洲央行 根据过去四次会议的持续降息情况,一个合同问"欧洲央行将在6月降息吗?"


步骤7 监控COT定位作为确认层

期货投机往往反映了相同的方向观点. 机器人机器人的仪表板 对于美元来说,指数显示大投机者是否是净长或短美元,即将进入CPI打印.如果规格是大量净长美元,CPI信号为NO (低于门),则有可能出现双边:预测市场合约可能值得消退,外汇仓位也可能容易受到挤压.

通过程序来提取COT数据,将其纳入您的信号框架:

def get_cot(currency: str) -> list[dict]:
    url = f"{BASE}/cot/{currency}?api_key={API_KEY}&limit=4"
    resp = requests.get(url, timeout=10)
    resp.raise_for_status()
    return resp.json().get("data", [])

usd_cot = get_cot("usd")
if usd_cot:
    latest = usd_cot[0]
    net_position = latest.get("net_position")
    print(f"USD spec net position (latest week): {net_position:+,.0f} contracts")

让我们一起做

整个工作流程看起来是这样:

  1. 拉起这个 发布日程 确定即将到来的公告和预定时间.
  2. 赛事公告日期为 开放预测市场合同 在卡尔希或聚市场上.
  3. 拿来一个 预测终点 对于当前的共识值.
  4. 计算一个 历史惊喜系列 为了测量方向偏差和基率.
  5. 产生一个 方向信号 通过将共识与合同值进行比较.
  6. 选择性地加上 机器人位置 作为确认信号.
  7. 根据合同中暗示的概率与实证基准利率估计之间的差距,
关于解决方案时间的重要注意事项
提供第二级的FXMacroData announcement_datetime 每个发布的时间对于预测市场至关重要,预测在官方打印后几秒内解决.始终确保合同的声明解决源 (例如"2026年3月的BLS CPI,首次发布") 与您查询的FXMacroData指标和修订标志完全匹配.预估和最终修订将作为单独的数据点存储.

开始吧

本指南中使用的所有终点均可免费试用,不需要信用卡.包括CPI,NFP,GDP,失业率,核心PCE和政策利率在内的美元指标均可在免费层面上访问.非美元指数和COT数据需要专业计划.
