The luxor.1.strategy.basic.R strategy doesn't cancel old unfulfilled

book  = getOrderBook(portfolio=portfolio.st)
book$forex$GBPUSD['2002-10-22/2002-10-24']

>From above orderbook you can see that at the short position taken
on 2002-10-24 02:00:00 is actually from the stoplimit order from 2002-10-23
17:00:00. and the short position taken on 2002-10-24 03:00:00 is actually
from the stoplimit order from 2002-10-24 01:30:00
