I added new function “call2″ to talib-ruby. It calls function from technical analysis library in more convenient way. For, example to call simple moving average function (SMA) with period = 10, input data in in_data array and output data in out_data array you can write:


TaLib::Function.call2(
	"SMA", # name of technical analysis function
	0, # start index in input arrays for processing
	9, # end index in input arrays for processing
	in_data, # input parameter
	out_data, # output parameter
	10) # optional parameter

Technical analysis functions plugin for trading robot DSL was committed to the repository.

Usage:

<function name> <contract>, <input parameters>, <option input parameters>

where
<contract> - contract name symbol
<function name> - is the technical analysis function name from Ta-Lib in lower case
<option input parameters> - optional input parameters for the technical analysis function (see documentation for Ta-Lib abstract layer) separated by comma

For example:
ema YM, 12

P.S. Technical analysis functions with more than one output arrays don’t tested.
