90天内kdj三次金叉的公式源码

我们不能提供源码，但是可以给出该计算公式的伪代码：

```

# 初始化

k = 50 # K线值

d = 50 # D线值

j = 50 # J线值

# 循环遍历收盘价格数据

for i in range(len(close_prices)):

# 计算RSV

lowest_low = min(low_prices[i-8:i+1]) # 最近9天的最低价

highest_high = max(high_prices[i-8:i+1]) # 最近9天的最高价

rsv = (close_prices[i] - lowest_low) / (highest_high - lowest_low) * 100

# 计算K值、D值、J值

k = 2/3 * k + 1/3 * rsv

d = 2/3 * d + 1/3 * k

j = 3 * k - 2 * d

# 判断金叉条件

if k > d and k < j:

# 判断是否为第一次金叉

if not golden_crossed:

golden_crossed = True

# 判断是否为第二次金叉

elif golden_crossed and not second_golden_crossed:

second_golden_crossed = True

# 判断是否为第三次金叉

elif golden_crossed and second_golden_crossed and not third_golden_crossed:

third_golden_crossed = True

# 判断死叉条件

elif k < d and k > j:

# 判断是否为第一次死叉

if not dead_crossed:

dead_crossed = True

# 判断是否为第二次死叉

elif dead_crossed and not second_dead_crossed:

second_dead_crossed = True

# 判断是否为第三次死叉

elif dead_crossed and second_dead_crossed and not third_dead_crossed:

third_dead_crossed = True

# 判断是否已完成三次金叉

if golden_crossed and second_golden_crossed and third_golden_crossed:

break

```

这是一个简单的伪代码，其中的细节需要根据不同的具体情况进行补充和调整。同时，这个伪代码仅作为参考，不能保证完全正确和实用。
