Pine script 你能把Pine脚本V.2转换成V.4吗

你能帮我把这个

V.2

Pine脚本转换成

V.4

吗。我尽了最大努力，但没能完成

当我试图运行此代码时。错误总是从以下行开始出现：

x=thisCCI>=0？缓冲区：thisCCI=0且lastCCI<0） bufferUp:=bufferDn[1] 如果（0） bufferDn:=bufferUp[1] 如果（thisCCI>=0） if（bufferUp=0？缓冲区：thisCCI x[1]？1:x=0？石灰：红色 swap4=原始？swap3:swap2 绘图（x，颜色=swap4，传输=0，线宽=2） bullTrendMagic=swap4==石灰和swap4[1]==红色 bearTrendMagic=swap4==红色和swap4[1]==石灰

---

转换为Pine脚本
