I happened to notice that the example below doesn’t include reference to the limit price. Support also brought to my attention superfluous spaces in my coding of the order URL, which I had copied as a template from the Developer API webpage example below. For those copying the code be advised that spaces will need to be removed between collective2 and .com and between signal. and mpl?
“You want to buy 5 contracts of the E-Mini S&P at limit 1120 or better, good til cancel.
Your program calls the following URL (all on one line):
http://www.collective2 .com/cgi-perl/signal. mpl?cmd=signal&
systemid=1234&pw=abcd&instrument=future&action=BTO&quant=5&
symbol=@ESM4&duration=GTC”
