Pine 脚本复杂请求多时间范围

Question

我知道具有较高时间范围的安全请求的原理，但在两个请求上遇到了困难。 打开/关闭和 HA 的标准非常完美：

[m_open_conf,m_open_real,m_close_conf,m_close_real] = request.security(syminfo.tickerid, "M", [open[1],open,close[1],close], lookahead = barmerge.lookahead_on)
[m_ha_open_conf,m_ha_open_real,m_ha_close_conf,m_ha_close_real] = request.security(ha_ticker, "M", [open[1],open,close[1],close], lookahead = barmerge.lookahead_on)

对于以下两种情况我该如何做到这一点？我已经尝试了很多可能性，但没有一个起作用。

1)

curve = ta.wma(ta.roc(source, longRoCLength) + ta.roc(source, shortRoCLength), wmaLength)

esma(source, length)=>
    s = ta.sma(source, length))
    e = ta.ema(source, length))
    po_exp ? e : s

我已经尝试过这两种情况：

m_po_short_conf = ta.sma(m_close_conf, 5)
m_po_long_conf = ta.sma(m_close_conf, 25)

m_curve_real = ta.wma(ta.roc(m_close_real, longRoCLength) + ta.roc(m_close_real, shortRoCLength), wmaLength)
m_curve_conf = ta.wma(ta.roc(m_close_conf, longRoCLength) + ta.roc(m_close_conf, shortRoCLength), wmaLength)

提前致谢

Answer 1

尝试将 request.security 与任何 function 一起使用，如下所示：

m_po_short_conf = request.security(syminfo.tickerid, "M",
                  ta.sma(close, 5)[1],
                  lookahead = barmerge.lookahead_on)  //No repaint
