美联储加息25个基点并暗示暂停，鲍威尔称“现在降息为时过早”
1. expma主图指标公式源码？
EXPMA（Exponential Moving Average）指数平均线，是一种基于指数移动平均原理计算的技术指标。其公式为：
$$
EXPMA(n) = 2/(n+1) * (Close - EXPMA(n-1)) + EXPMA(n-1)
$$
其中，n为指数平均线的周期，Close为当前的收盘价。
以下是Python代码实现：
```python
def expma(close, n):
ema = close.ewm(span=n, adjust=False).mean()
return 2 * ema - ema.ewm(span=n, adjust=False).mean()
```
在这里，`close`是收盘价的时间序列数据，`n`是指数平均线的周期。使用`pandas`库中的`ewm`函数可以方便地计算指数平均线。
2. boll指标公式源码？
BOLL布林线指标源码
M:=20;
BOLL:MA(CLOSE,M);
UB:BOLL+2*STD(CLOSE,M);
LB:BOLL-2*STD(CLOSE,M);
动态翻译：
M赋值:20
输出BOLL:收盘价的M日简单移动平均
输出UB:BOLL+2*收盘价的M日估算标准差
输出LB:BOLL-2*收盘价的M日估算标准差
用法：
1、股价上穿布林线上限时，回挡机率大；
2、股价下跌穿越下限时，反弹机率大；
3、布林线震动菠带变笮时表示变盘在即;
4、BOLI司配合BB、WIDTH使用
3. 超准kd指标公式源码？
输出INPUT:N(45),M(10),M1(4),N1(14)
RSV赋值:(收盘价-N日内最低价的最低值)/(N日内最高价的最高值-N日内最低价的最低值)*100
K赋值:RSV的M日[8日权重]移动平均
D赋值:K的M1日[1日权重]移动平均
J赋值:(3*K-2*D)
MID赋值:D的N1日简单移动平均
输出AD:(RSV-MID)/MID*100, COLORSTICK
输出AD1:(RSV-MID)/MID*100,画白色,线宽为1
输出活跃界:50,POINTDOT,画绿色
输出SX:110,POINTDOT,画红色
输出DX:200,POINTDOT,画黄色
