My quanstrat strategy returns an error which I didnt find being discussed yet.
Strategy is very simple: calculate rolling sum over given period of time. If the rolling sum is over some threshold, enter long and submit siultanesouly two oco orders, take-profit and stop loss in the distance of +/- 5%.
The code is:
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)

Data structure is as follows:

"ask.vol", "vol", "bid.freq", "ask.freq", "freq", "bid.price",
"ask.price", "price")))
It is an xts object showing bid/ask volume/frekvency of trades in one second and the mentioned error says:
[1] "2014-09-24 22:00:17 data 1 @ 407"
Error in dindexOrderProc(openOrderSubset[i, ], mktPrices, curIndex) :
no price discernable for limit in applyRules
There doesnt seem to be a problem with order-chain as orderbook contains all three orders with correct prices:
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"
Any ideas?
I somewhere found specifying the limit order price like:
order.price=quote(data$ask.price[timestamp])
but it didn't work out.
Removing some columns from mktdata and moving the price column to the very left solved the issue.
