Python中RSI背离检测代码在15分钟时间间隔下出现KeyError的解决求助

我正在开发一个用于检测RSI背离的程序，遇到了一个奇怪的问题：当时间间隔设为60分钟时，程序能正常运行；但改成15分钟后，程序就会崩溃，抛出KeyError: 11的错误。以下是我的代码和完整报错信息，希望能得到大家的帮助，找出问题所在。

数据获取与RSI计算代码 #

import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
import yfinance as yf
import ta

ticker=yf.Ticker("ADA-USD")

data=ticker.history(period="10d",interval='15m')
data.rename(columns={"Close":"close","High":"high","Low":"low","Open":"open"},inplace=True)
data.index=range(1,len(data)+1)

rsi_peroid=14
data["rsi"+str(rsi_peroid)]=ta.momentum.RSIIndicator(data["close"],rsi_peroid).rsi()
data.dropna(inplace=True)

背离检测逻辑代码 #

divergence_point=[]
rsi_val=data["rsi14"]
loop=10
for i in range(loop,len(data)-1):
    recent_rsi=rsi_val[i-loop:i]
    recent_price=data["close"].iloc[i-loop:i]
    if (data["close"].iloc[i] < min(recent_price) and rsi_val[i] >= min((recent_rsi)+2) or data["close"].iloc[i] > max(recent_price) and rsi_val[i]<= max(recent_rsi)-2):
        divergence_point.append(i)
        
data["Divergence"]=False

data.loc[divergence_point,"Divergence"]=True

完整报错信息 #

The above exception was the direct cause of the following exception:

KeyError: 11

再次说明下情况：当时间间隔设为60分钟时程序完全正常，但切换到15分钟间隔就会触发这个错误，我实在搞不懂哪里出问题了，求各位大佬指点！
