问题描述
希望有敏锐眼光的人可以帮助我.当我运行下面的两个代码块时,第一个块运行良好:
Hoping someone with a sharper eye can help me out. When I run the two blocks of code below, the first chunk goes fine:
add.rule(strategy.st, name = "ruleSignal",
arguments = list(sigcol = "exitLongNormal",
sigval = TRUE,
orderqty = "all",
ordertype = "market",
orderside = "long",
replace = FALSE,
prefer = "Open",
type = "exit", path.dep = TRUE, label = "normalExitLong")
add.rule(strategy.st, name = "ruleSignal",
arguments = list(sigcol = "exitLongFilter",
sigval = TRUE,
orderqty = "all",
ordertype = "market",
orderside = "long",
replace = FALSE,
prefer = "Open",
type = "exit", path.dep = TRUE, label = "filterExitLong")
运行时初始块给了我这个:
When ran the initial block gives me this:
> add.rule(strategy.st, name = "ruleSignal",
+ arguments = list(sigcol = "exitLongNormal",
+ sigval = TRUE,
+ orderqty = "all",
+ ordertype = "market",
+ orderside = "long",
+ replace = FALSE,
+ prefer = "Open",
+ type = "exit", path.dep = TRUE, label = "normalExitLong")
然而,第二块是问题孩子,运行时我得到以下信息:
Block two however, is the problem child, when ran I get the following:
Error: unexpected symbol in:
" type = "exit", path.dep = TRUE, label = "normalExitLong")
add.rule"
这似乎很容易找到,但对于我的生活,我就是无法弄清楚.提前感谢您的任何意见.
It seems like this would be something pretty simple to find, but for the life of me I just can't figure it out. Thanks in advance for any input.
推荐答案
这是不匹配的括号:
add.rule(strategy.st, name = "ruleSignal", # OPEN
arguments = list(sigcol = "exitLongNormal", # OPEN
sigval = TRUE,
orderqty = "all",
ordertype = "market",
orderside = "long",
replace = FALSE,
prefer = "Open",
type = "exit", path.dep = TRUE, label = "normalExitLong") # CLOSE
