CLX9 has over 2000 open interest, so we would reasonably expect it to have some trades. But the following always return empty data table with a warning message. I am not sure whether the data is not available or there is issue with the processing of the data. Could you kindly take a look at this? Thanks a lot!
QCLX19 <- get_iqfeed_data('QCLX19', from='2017-04-08', to='2017-08-09', period='tick') Warning message: In
:=(from, from + 1)) : Coerced 'double' RHS to 'integer' to match the column's type; may have truncated precision. Either change the target column to 'double' first (by creating a new 'double' vector length 3 (nrows of entire table) and assign that; i.e. 'replace' column), or coerce RHS to 'integer' (e.g. 1L, NA_[real|integer]_, as.*, etc) to make your intent clear and for speed. Or, set the column type correctly up front when you create the table and stick to it, please.
