我的量化策略返回了一个我没有发现正在讨论的错误。Quanstrat策略 - 错误
策略非常简单:计算给定时间段内的滚动总和。如果滚动数量超过某个阈值,请进入多头并提交两个oco订单,在+/- 5%的距离内获利和止损。
的代码是:
require("quantstrat")
from <- "2014-09-25"
to <- "2014-10-01"
rm(strategy.st)
try(rm("account.st","portfolio.st"),silent=TRUE)
.blotter <- new.env()
.strategy <- new.env()
initDate <- as.character(as.Date(from) - 1)
currency("USD")
Sys.setenv(TZ = "UTC")
symbols <- "data"
stock(symbols, currency = "USD", multiplier = 1) # Initialisation of the instrument
tradeSize <- 1 # Initialisation of trade size
initEq <- 1000 # Initialisation of initial equity
strategy.st <- "btc" # Initialisation of the strategy
portfolio.st <- "btc" # Initialisation of the strategy, must be after strategy
account.st <- "btc" # Initialisation of the strategy, must be after strategy and portolio
initPortf(portfolio.st, symbols=symbols, initDate=initDate, currency='USD')
initAcct(account.st, portfolios=portfolio.st, initDate=initDate, currency='USD',initEq=initEq)
initOrders(portfolio.st, initDate=initDate)
strategy(strategy.st, store=TRUE)

它是一个XTS对象表示买入/卖出交易的体积/ frekvency在一个第二和提到的错误说:
[1] "2014-09-24 22:00:17 data 1 @ 407"
Error in dindexOrderProc(openOrderSubset[i, ], mktPrices, curIndex) :
no price discernable for limit in applyRules
似乎没有订单链的问题,因为订单包含所有三个订单s正确的价格:
Order.Qty Order.Price Order.Type Order.Side Order.Threshold Order.Status Order.StatusTime Prefer Order.Set Txn.Fees
2014-09-24 22:00:16 "1" "407" "market" "long" NA "closed" "2014-09-24 22:00:17" "ask" "ocolong" "0"
2014-09-24 22:00:17 "all" "386.65" "stoplimit" "long" "-20.35" "open" NA "" "ocolong" "0"
2014-09-24 22:00:17 "all" "427.35" "limit" "long" "20.35" "open" NA "" "ocolong" "0"
任何想法?
我发现某处指定如限价令价格:
order.price=quote(data$ask.price[timestamp])
,但没有成功。
嗨Steef,还没有到它的底部还没有,但希望这会有所帮助。所产生的错误信息是由 触发如果(is.na(mktPrice)|| is.null(mktPrice)) 停止( “没有价格可辨的” 订单类型 “在applyRules”) 上applyStrategy右边的错误呈现? – OliE 2014-12-01 11:23:03
嗨,奥列,我追溯了这个错误,是的,你是对的。错误来自applyStrategy,指标和信号是正确的。我认为这个错误来自于限制订单规则中的order.price声明,因为我的数据不是(也不能)以OHLC格式存在,所以这个订单不知道从哪里收取价格。我试过类似order.price = quote(data $ ask.price [timestamp]),但它不起作用。 – 2014-12-03 10:01:42
重新排列您的数据,以便价格优先。如果您没有指定价格列,例如通过'prefer'参数,然后quantstrat将调用'getPrice',并尝试猜测。它应该能够检测出价/询价数据,但预计价格会在BBO数据集中的补充数据之前出现。 – 2014-12-09 10:17:32
