如何为R中的Quantstrat编写自定义规则函数-用ruleOrderProc替换尾随停止顺序
如何为R中的Quantstrat编写自定义规则函数-用ruleOrderProc替换尾随停止顺序
提问于 2018-03-02 12:20:39
我的目标是使用下面概述的规则生成一个信号，发出一个新的“stoplimit”命令，取代我的尾声停止。，我不想让我的止损无限期地拖下去，直到它达到我的盈亏平衡价格(如果这已经可以实现，请告诉我)。
我希望用quantstrat编写一个自定义规则，其目标如下：
如果今天的“关闭”减去(-)贸易开放时间戳上的阈值(一个标量)大于(>)贸易开放时间戳上的“开放”价格(这也是填充值或order.price)，那么生成一个交易(我也只希望这种情况发生一次，所以类似于交叉= T)。
For example:
Open a Trade on 01-01-2000 @ $150.00
Threshold value on 01-01-2000 is $5.00
Today's Close on 02-01-2000 = "$155.50"因为今天的收盘价减去门槛是>填充价格，所以产生一个信号来下单。问题是，我认为这不能用add.signal完成，至少在add.rule函数之外是不行的，因为我需要访问订单簿。我不能预先计算mktdata对象，因为我有许多不生成订单的输入信号，而单看mktdata，就无法判断哪些信号导致了订单。
有人能告诉我add.rule()的哪一部分是我需要适应的才能做到这一点吗？如果我需要编写我自己的ruleSignal 函数，那么由于提前没有信号，我应该为σ和sigval写些什么？
以下是我目前的长期交易规则：
# Long Entry
add.rule(strategy.st, name = 'ruleSignal',
arguments = list(sigcol = 'longSig',
sigval = TRUE,
replace = F,
orderside = 'long',
ordertype = 'market',
osFUN = osATR,
prefer = 'Open'),
type = 'enter',
label = 'enterLong',
path.dep = T)
# Long Stop
add.rule(strategy.st, name = 'ruleSignal',
arguments = list(sigcol = 'longSig', sigval = T,
orderqty = 'all', ordertype = 'stoptrailing',
orderside = 'long',
replace = F,
threshold = 'stpVal'),
orderset = 'goLong',
type = 'chain',
path.dep = T,
parent = 'enterLong')任何帮助都是非常感谢的，我将分享我的成果。谢谢!

您在quantstrat中修改核心ruleOrderProc函数的解决方案似乎不错。如果您正在寻找一个不需要修改quantstrat代码的开箱即用的解决方案，您可以使用方便的"trigger" order qty参数。正如在ruleSignal的quantstrat文档中所指出的，在ruleSignal.R中可以找到
\code{orderqty}应该是数字，或者是“all”/“触发器”之一。“‘all”只能按规则类型=“退出”或“风险”的顺序使用，并将关闭整个头寸。‘'trigger’只能与ruletype=' chain‘一起使用，并且与'all’完全相同，只是实际的事务被抑制了，并且可以用来启动一个新的订单链。
这是一个自我包含的简化策略，我认为它可以做你想做的事情。
请注意，如果填充了触发器的限制顺序，则不会发生实际的事务(查看ruleOrderProc的源，如果addTxn是trigger数量，则不会被调用)。
仪器为GBPUSD，数据来自量化数据。当MACD信号从下方穿过0时，该策略进入长位置。如果MACD信号在0以下过，则退出任何开放的多头位置。如果价格在入市时上涨超过价格的0.05% (记住这是一个外汇汇率，相对于股票)，那么任何开放的尾盘止损都将被转换为股票。
这种方法需要定义一个新的规则函数来处理从停止到stoplimit的转换。

# We can see the price first touches 1.5490 on the 2002-10-20 22:21:00 bar, which is the timestamp at which the stoptrailing is closed and the stoplimit is opened in the orderbook.Stack Overflow用户

通过更改quantstrat::ruleOrderProc的源，我找到了一个临时解决方案。
你可以在这里找到主分支--> quantstrat::ruleOrderProc
几个注意事项：我正在使用OHLC日常数据。这将不适用于BBO或滴答数据。也没有办法恢复到永久的尾随停止。每当我的stoplimit订单达到我的起始价格时，我的更改就会下stoptrailing订单。
在347 > elseif(isOHLCmktdata) {的github主支行347行附近
我做了以下修改：
else if(isOHLCmktdata)
{
# check to see if price moved through the limit THE IS A "CLOSED" ORDER
order.side <- ordersubset[ii, "Order.Side"]
if(order.side == 'long' && as.numeric(Lo(mktdataTimestamp)[,1]) < orderPrice
|| order.side == 'short' && as.numeric(Hi(mktdataTimestamp)[,1]) > orderPrice)
{
txnprice <- orderPrice
txntime <- timestamp
}
else
{
# THIS IS WHERE THE TRAILING STOP IS ADJUSTED
# Get order threshold
order.threshold <- as.numeric(ordersubset[ii, "Order.Threshold"])
order.qty <- ordersubset[ii, "Order.Qty"] # if orderQty='all' we must recover it
# Get the fill price
transactions <- getTxns(Portfolio = portfolio, Symbol = symbol)
last.transaction <- tail(transactions, 1)
trans.price <- last.transaction[,2]
if(order.side == 'long')
new.order.price <- max(orderPrice, as.numeric(Hi(mktdataTimestamp)[,1]) + order.threshold)
if(order.side == 'short')
new.order.price <- min(orderPrice, as.numeric(Lo(mktdataTimestamp)[,1]) + order.threshold)
if(new.order.price != orderPrice)
{
if (order.side == 'long' && new.order.price > trans.price || order.side == 'short' && new.order.price < trans.price) {
# Add an order with a stoplimit order type
neworder<-addOrder(portfolio=portfolio,
symbol=symbol,
timestamp=timestamp,
qty=order.qty,
price=new.order.price - order.threshold,
ordertype='stoplimit',
side=order.side,
threshold=order.threshold,
status="open",
replace=FALSE, return=TRUE,
orderset=ordersubset[ii,"Order.Set"],
label=ordersubset[ii,"Rule"],
,...=..., TxnFees=txnfees)
} else {
# adjust trailing stop
neworder<-addOrder(portfolio=portfolio,
symbol=symbol,
timestamp=timestamp,
qty=order.qty,
price=new.order.price - order.threshold,
ordertype=orderType,
side=order.side,
threshold=order.threshold,
status="open",
replace=FALSE, return=TRUE,
orderset=ordersubset[ii,"Order.Set"],
label=ordersubset[ii,"Rule"],
,...=..., TxnFees=txnfees)
}
ordersubset<-rbind(ordersubset, neworder)
ordersubset[ii,"Order.Status"]<-'replaced'
ordersubset[ii,"Order.StatusTime"]<-format(timestamp, "%Y-%m-%d %H:%M:%S")
next()
}
}
}
} # end stoptrailing主要的变化是得到填充价格。
# Get the fill price
transactions <- getTxns(Portfolio = portfolio, Symbol = symbol)
last.transaction <- tail(transactions, 1)
trans.price <- last.transaction[,2]然后添加这个if语句
if (order.side == 'long' && new.order.price > trans.price || order.side == 'short' && new.order.price < trans.price) { 发出stoplimit命令，而不是无限期地移动停止。到目前为止，它一直在正常工作。
