问题
My goal is to use the rule that I outline below to generate a signal to place a new 'stoplimit' order that replaces my trailing stop. I don't want my stop to trail indefinitely, only until it reaches my breakeven price (if this can be achieved somehow already, please let me know).
I am hoping to write a custom rule in quantstrat with the following objective:
If today's "Close" minus (-) the threshold value (a scalar) on the timestamp of trade open, is greater than (>) the "Open" price on timestamp of trade open (this is also the fill value or order.price) THEN generate a trade (I'd also only like for this to occur one time so something like cross = 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"
Since today's close minus the threshold is > fill price, generate a signal to place an order. The issue is I don't think this can be done with add.signal, at least not outside of the add.rule function because I need access to the order book. I can't pre-calculate on the mktdata object because I have many entry signals that do not generate orders, and looking at mktdata alone, there is no way to tell which signals resulted in an order.
Could someone advise me what part of add.rule() I need to adapt to make this possible? If I need to write my own ruleSignal function, what do I put for sigcol and sigval since I have no signal ahead of time?
Here are my current rules for a long trade:
# 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')
Any help is appreciated and I will share my results. Thank you!

Your solution of modifying the core ruleOrderProc function in quantstrat seems fine. If you're looking for an out of the box solution to your problem that doesn't require modifying the quantstrat souce code, you could make use of the handy
"trigger" order qty argument. As noted in the quantstrat documentation for the ruleSignal found in ruleSignal.R:
\code{orderqty} should be either numeric, or one of 'all'/'trigger'. 'all' can only be used with order of ruletype='exit' or 'risk', and will close the entire position. 'trigger' can only be used with ruletype='chain' and is exactly identical to 'all', except that the actual transaction is suppressed, and can be used to kick in a new order chain.
Here is a self contained simplified strategy that I think does what you want.
Note that if the limit order with the trigger is filled, there is no actual transaction that takes place (look at the source for ruleOrderProc and you'll see that addTxn doesn't get called if it's a trigger quantity).
The instrument is GBPUSD, and the data is from quantstrat. The strategy enters a long position when the MACD signal crosses 0 from below. If the MACD signal then crosses below 0, any open long positions are exited. If the price increases by more than 0.05% of the price (remember this is an FX rate so smaller percent moves are expected compared to say equities) at the time of entry, then any open trailing stop will be converted to a stoplimit.
This approach requires defining a new rule function that handles the conversion from the stoptrailing to stoplimit.

# 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.

I was able to find a temporary solution by changing the source of quantstrat::ruleOrderProc
You can find the master branch here ---> quantstrat::ruleOrderProc
A few notes: I am using OHLC daily data. This will not work with BBO or tick data. There is also no way to revert to a permanently trailing stop. My alteration places a stoplimit order whenever my stoptrailing order reaches my entry price.
Near line 347 on the github master branch at 347 > elseif(isOHLCmktdata) {
I made the following changes:
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
The major change is getting the fill price
# Get the fill price
transactions <- getTxns(Portfolio = portfolio, Symbol = symbol)
last.transaction <- tail(transactions, 1)
trans.price <- last.transaction[,2]
and then adding this if statement
if (order.side == 'long' && new.order.price > trans.price || order.side == 'short' && new.order.price < trans.price) {
to place a stoplimit order instead of moving the stop indefinitely. So far it has been working properly.
