sar股票指标秒懂百科 (sar指标公式源码精准版)

```python

SAR指标计算函数

def calculate_sar(high, low, acceleration=0.02, maximum=0.2):

af = acceleration

ep = low[0]

sar = low[0]

trend = 1

trend_switch = False

sar_values = []

for i in range(1, len(high)):

if trend == 1:

if high[i] > ep:

ep = high[i]

af = min(af acceleration, maximum)

if low[i] < sar af * (ep sar):

sar = low[i]

trend = 1

trend_switch = True

else:

if low[i] < ep:

ep = low[i]

af = min(af acceleration, maximum)

if high[i] > sar af * (sar ep):

sar = high[i]

trend = 1

trend_switch = True

sar_values.append(sar)

if trend_switch:

trend_switch = False

ep = high[i 1]

sar = sar_values[1]

af = acceleration

return sar_values

```

这是一个简单的Python函数，用于计算SAR指标（停损和换仓点）。如果需要根据特定的数据进行计算，可以将股票的更高价和更低价数据传入该函数，并可以选择性地设置加速因子和更大值。
