Hi Stergios
I believe it is your ratios. They have to be integers.
your second one is
ratio = 1.06
You will have to calculate the most feasible rational approximation to
your beta of
-1.06/1
One solution would be
-21/20 ~ -1.05
So you could set
leg1: ratio = 21
leg2: ratio = 20
Dear Bhavna
I had quick look at your code. If you define your T3 function like
this (as Brian has already suggested), the whole thing runs fine (and
fast), as long as you also reduce your 'nseData' to a single column,
i.e. the Close. If you need all OHLC columns then you need to have a
closer

It's not clear to me what you're trying to do. An example would help.
My guess is that you're looking for something like this:
x - xts(1:10, Sys.Date()-10:1)
rbind(x, xts(NA_integer_,Sys.Date()-11))

Dear Noah
one way to find out if your order was filled (and how much of it, and
at what price) is to use reqExecutions(). It is documented in the IB API
reference guide. The 'IBrokers' package implements it as a function, so
you can look at it's source there. An example of how to read execution
-match(NA, idxcol[[1]] )
fill it with the data from newbar
mmapPrices[iifree,1] - .index(newbar)
mmapPrices[iifree,2] - coredata(newbar)[1,1]
This has been working fine for me.

Hi there,
I am now trying the qsiblive by Soren, and it requires a daily marketdata

I download the rgarch package from

Hi
well, I am currently testing an intraday version of the 'qsiblive'

working fine (looking at realTimeBars only). One has to be mindful of
indicator and signal calculations though. If these slow things down to
much, using
