如何正确减少来自 Pine Script 的安全调用? [英] How to correctly reduce security calls from Pine Script?

问题描述

我正在尝试制作一个仪表板，为多个符号计算相同的条件

我目前正在调用这样的安全功能，因此我可以将它用于多个符号.但是，如您所见，这需要 4 次安全调用.

getCandle(symbol) =>_open = security(符号，240"，打开)_close = security(符号，240"，关闭)_high = 安全性(符号，240"，高)_low = 安全性(符号，240"，低)[_open, _close, _high, _low]

然后我的脚本为不同的符号重复调用此函数，如下所示

[_open, _close, _high, _low] = getCandle(OANDA:USDJPY")//用蜡烛做点什么

我有 20 多个符号，所以我很快就遇到了最大安全调用/脚本错误.

为了优化这一点，我按照文档中所示进行了尝试

getCandle(symbol) =>[_open, _close, _high, _low] = security(symbol, "240", [open, close, high, low])

在我进行此更改的那一刻，我在控制台上收到了大量错误，内容类似于

line 85: 不能用参数调用'anonym_function_10' (fun_arg__<anonym_function_7_arg0_type>, fun_arg__<anonym_function_7_arg1_type>, fun_arg__<anonym_function_7_arg2_type>integer_input> integer_type>输入第 85 行:无法使用参数调用anonym_function_11"(fun_arg__
I am trying to make a dashboard which calculates same condition for multiple symbols

I am currently calling security function like this, so I can use it for multiple symbols. However, as you can see it takes 4 security calls.
getCandle(symbol) =>
    _open = security(symbol, "240", open)    
    _close = security(symbol, "240", close)
    _high = security(symbol, "240", high)
    _low = security(symbol, "240", low)
    [_open, _close, _high, _low]
This function is then repeatedly called for different symbols by my script as follows
[_open, _close, _high, _low] = getCandle("OANDA:USDJPY")
// do something with the candle
I have 20+ symbols, so I quickly ran into max security calls/script error.
To optimize this, I tried as shown in the docs
getCandle(symbol) =>
    [_open, _close, _high, _low] = security(symbol, "240", [open, close, high, low])
The moment I make this change, I get huge number of errors on the console which read something like
line 85: Cannot call 'anonym_function_10' with arguments (fun_arg__<anonym_function_7_arg0_type>, fun_arg__<anonym_function_7_arg1_type>, fun_arg__<anonym_function_7_arg2_type>, fun_arg__<anonym_function_7_arg3_type>, input integer, input integer);
line 85: Cannot call 'anonym_function_11' with arguments (fun_arg__<anonym_function_7_arg0_type>, fun_arg__<anonym_function_7_arg1_type>, fun_arg__<anonym_function_7_arg2_type>, fun_arg__<anonym_function_7_arg3_type>, input integer, input integer);
line 85: Undeclared identifier '#var_24';
Can someone please help to understand what is incorrect in the optimized code?
Thanks a bunch!
解决方案
hm, works for me:
(you don't even need the getCandle function anymore at this point)
// © marketscripters

//@version=4
study("My Script")

[_open, _close, _high, _low] = security("GBPUSD", "240", [open, close, high, low])
[_o2, _c2, _h2, _l2] = security("EURUSD", "240", [open, close, high, low])

plot(_low)
plot(_high)
plot(_l2, color=color.green)
plot(_h2, color=color.green)
