Pine 脚本指示器问题（可能是代码过时了）
Pine script indicator problem (probably code outdated)
我是 Pine 脚本的新手，更多的是 R 用户，所以 pine 脚本代码很容易理解，但我遇到了名为“Open Interest:CME e-o-d vs CFTC e-o-w”的指标问题 - 价格线(contracts sum) 没有显示 plot(OiSum>0?OiSum:na, color=purple, title="CME e-o-d\n 9 cntrcts sum", linewidth=3,offset=OffSet)，可能是因为没有收集合同数据。
主要问题是我找不到函数描述“getCntrct”，因此我无法理解它的去向 e.t.c。
任何帮助都是完美的。

getCntrct() 函数用于构造 ticker/quandl 代码并通过安全调用检索 OI 值。
脚本要求您手动指定合约的前缀，黄金和白银除外。对于那些，如果您将图表代码更改为 XAUUSD 或 XAGUSD，您将看到脚本绘制 OI 值。
对于其他人，例如对于澳元 OI 值，您必须将“覆盖符号（SI/CL 等）”设置更改为“AD”（输入变量 ChkComm）
对于澳元，这将为安全调用构建 quandl 代码：
